Description

[0001] SPINNING ACCESSORY

[0002] The present invention relates to a spinning accessory for use on a finger or thumb. This may be used by adults or children and can be used as a toy or a game accessory, or as a piece of sports kit, or as an accessory in relation to health monitoring or improvement. The accessory facilitates micro movement by the user. The accessory may, in embodiments, be used for fidget relief, to improve co-ordination, to improve concentration and challenge the mind, to improve motor skills and to improve bi-manual co-ordination.

[0003] Background to the Invention

[0004] Handheld toys or accessories are known in the art and include spinning tops, yo-yos and hand spinners (“fidget spinners”). Hand spinners have a central roller bearing that is set in the middle of a balanced body which may, for example, comprise a number of symmetrically arranged arms. The roller bearing can be held in the fingers of one hand and the body can then be spun, e.g. by the fingers of the other hand flicking the arms. This provides the user with visual feedback.

[0005] Jewellery type accessories are also known which involve spinning. These spinning rings (“worry rings”) have two bands arranged such an outer band of the ring stays in place while the inner band spins, or vice versa. The user can wear the spinning ring on a finger of one hand and use a finger of their other hand to rotate the spinning band.

[0006] Various exercise devices are also known that involve spinning, such as the hula hoop.

[0007] A number of exercise devices are known that are both spinning and weight bearing and that are used on a jointed muscle appendage, such as an arm or leg, with the aim of building up muscle strength. The balls are weighted to achieve a load bearing device and the weighted ball creates centrifugal force, leading to resistance and muscle training.

[0008] US2023302342A1 provides a device for exercise that comprises a body having a substantially circular shape and a cavity therein, with there being one or more weighted ball located inside the cavity. A person engages in weight bearing exercise by wearing the device on an arm or leg and moving the limb, causing the balls within the device to move around the cavity of the device. An exterior portion of the device is clear or translucent, allowing the balls to be observed. The balls may be coloured, or may light up when moved, or may make a sound when moved. Therefore the user obtains visual or audible feedback. The device may include an opening to allow a person to add or remove balls from the interior of the device. US4938477A describes a wrist exercising device consisting of a hollow cylindrical member in the form of a torus which can be strapped to the wrist and can have one or more weighted balls rotating around the track formed by the outer shell of the torus, with the weight being controlled by the number of balls and the weight thereof. This permits the user to secure the device to the wrist and by rotating the wrist or swinging the arms, a full range of exercises may be undertaken. This acts to strengthen the muscles in the wrists, arms, shoulders and the upper part of the body.

[0009] IT201800002850A1 provides a device for muscle training of the legs. The device includes a toroid inside which a weighted sphere is located, and the device is fixed to the ankle. Through the circular movement of the sphere inside the toroid a centrifugal force is produced. The resistance that the leg develops against this centrifugal force produces the desired muscle training.

[0010] W02005023375A1 describes a device for training delicate parts of the body such as the head. It includes a tube of semi-rigid material in the form of a closed ring, and this is worn in a coaxial position on the head. The closed ring is partially filled with a liquid, which provides weight and moves on a concentric path when the user starts the circular movement of their head.

[0011] US2013184123A1 provides an exercise device that can be used for developing strength in the hand or wrist, comprising a rigid endless tubular ring having an internal bore, a handle element which extends radially across a main aperture bounded by the ring, and a weighted freely movable element received in said ring for movement therearound. The handle element is attached to the tubular ring via first and second attachment portions which extend around or substantially around a lateral extent of the tubular ring for improved stability.

[0012] Summary of the Invention

[0013] The present inventor recognised that there is a benefit in providing an outlet for movement for the user at all times, and in any environment. There is an advantage in this regard to focussing on movement, rather than resistance or strength training, as it is more versatile and universally useable across a range of locations and situations. It is also more achievable for a wide range of users of different ages and different levels of health and wellbeing. By enabling micro movements to take place, the user can remain active and alert when their environment prevents or deters them from carrying out conventional exercise or even general movement. The present invention provides a device that uses micro movements to overcome inertia. The device uses the intrinsic and extrinsic muscle groups found in the hand. It is not designed to activate larger muscle groups, and its use is focussed on a finger or thumb of the hand, not a jointed muscle appendage such as an arm or leg.

[0014] In addition, the present inventor recognised that many currently available accessories tend to require both hands for use, meaning that their use is not discreet or unobtrusive and further limits the occasions on which they can be used. For some other available accessories, such as the yo-yo, one-handed use is possible but the nature of the movement of a yo-yo is intrusive and again limits the occasions on which they can be used, requiring there to be an empty area adjacent the user into which the yo-yo can be spun.

[0015] The present inventor recognised that it would be valuable to have a one-handed spinning accessory that can be used easily, discreetly and - if desired - almost sub-consciously, and where the accessory can be easily transported or stored so that it can be used in a range of environments as and when desired or needed.

[0016] The present inventor also recognised that in some embodiments there is a benefit in providing haptic feedback to the user, to encourage continued use of the accessory, but that it may be useful to have little or no visual or audible feedback so as to support the use of the accessory in a discreet and unobtrusive manner and in a range of environments without distracting others.

[0017] The invention provides, in a first aspect, a spinning accessory for use by an adult or child on a finger or thumb, the accessory comprising:

[0018] • a housing defining an outer enclosed track which provides a closed loop circuit that extends around an inner central aperture; and

[0019] • one or more orbiting bodies that are housed within the enclosed track and that can freely move around the closed loop circuit; wherein the central aperture is sized and shaped to receive a finger or thumb, and whereby rotation of the housing causes the orbiting bodies to move around the closed loop circuit.

[0020] The accessory should be shaped and configured such that the user can pass the distal end of their finger or thumb through the central aperture, such that the accessory rests at a location on the finger or thumb, e.g. at around the location of the knuckle. In one preferred embodiment, the central aperture is sized and shaped to rest on the knuckle of the user’s finger or thumb, i.e. the aperture is smaller than the user’s knuckle and therefore the accessory does not rest at the base of the finger or thumb like a traditional ring.

[0021] The user can therefore place the accessory on their finger or thumb and can move that finger or thumb or the whole hand, e.g. with a rotating motion, to move the orbiting bodies around the closed loop circuit. It is therefore straightforward to “activate” the spinning accessory by causing motion of the orbiting bodies, which in turn provides sensory feedback to the user.

[0022] The motion involved when rotating the finger, thumb or hand is a micro movement, i.e. a small movement that can be made in a restricted environment. This is beneficial in that it allows the user to expend energy and / or improve their focus in a wide range of locations. It provides an outlet for movement for the user at all times. The accessory can be used at any time, and in any environment.

[0023] Micro movement is also advantageous because it results in homeostasis; this is relevant on many levels including regulating bodily functions.

[0024] Micro movement can be classified as NEAT (non-exercise activity thermogenesis) also known as NEPA (non-exercise activity activity) which is any movement or energy expenditure during activities that are not part of a structured exercise program.

[0025] The accessory allows the user to achieve activity levels in a range of environments, rather than being purely stationary. It enables the user to remain active when their environment prevents or deters them from carrying out conventional exercise. For example, it could be used whilst travelling, or when studying at school, college or university, or when at work. This in turn can optimise the user’s health and wellbeing. By facilitating micro movements, the accessory enables the user to maintain some level of movement and activity even when they are expected to be still.

[0026] The accessory also has the advantage of being able to be used even when the person is concentrating on something else, e.g. the spinning accessory could be used on a finger or thumb whilst the person was watching television, or whilst studying in a classroom or at home, or whilst a passenger in a car. Likewise, it may be used whilst the user is doing something else, for example an activity such as typing or reading. It may, in particular, be beneficial in environments where the user could otherwise lose concentration or might be vulnerable to bad habits, such as smoking or comfort eating, or displacement behaviours, e.g. nail biting or skin picking.

[0027] The user may be able to focus better or retain information better, for example memory and attention can be improved when the body has regular motion. It is believed that active learning helps with improved focus.

[0028] The design of the accessory enables the user to readily flick or spin the housing without needing to directly look at the accessory or take their focus off other tasks they may be undertaking, unlike other spinning toys that may require two hands and / or a visual focus. The accessory is simply placed on a finger or thumb and then used by simple motion of the user’s hand, or of the specific finger or thumb.

[0029] This accessory is beneficial in that it can be used by people of all ages, and with the ability to use the accessory in a one-handed manner.

[0030] A key benefit of the present invention is that action by another hand is not required and instead the user can rotate their finger or thumb to enable the orbiting bodies to rotate around the closed loop circuit. Therefore whilst it will be appreciated that the housing can be flicked in order to activate motion of the orbiting bodies, this is not the preferred way of using the device. The ability to activate the accessory on the finger or thumb by using a motion involving the same hand enables the individual to expel more energy, aiding the body to selfregulate and focus, and to release stress and pent-up energy. The accessory allows the user to maintain a constant internal environment (homeostasis).

[0031] Individuals are believed to fidget as a way of subconsciously refocusing and improving their attention. The present accessory assists with this refocusing process, by not requiring any visual attention whilst expelling energy and fulfilling / relieving the desire to move. The accessory can be used to exert as little or as much energy as needed, whilst obtaining haptic feedback with minimal distraction.

[0032] The spinning accessory may, in embodiments, find use in sports and in improving mental and physical health and wellbeing.

[0033] A sedentary life can lead to individuals gaining weight, leading to obesity and other illnesses. It is thought that it is not just exercise that people need, but also the option to keep moving / fidgeting. The need to move is actually a primary drive, in the same way as eating, sleeping and drinking. Such primary drivers can enable the body to self-regulate, regain focus and improve overall health. Thus, allowing your body to take part in fidgeting can lead to more happy and healthy individuals. However, a negative perception of fidgeting, e.g. linking such movement to being impatient or distracted, can lead to the suppression of fidgeting.

[0034] Micro movements can be described as fidgeting. The health benefits proven with this type of micro movement or fidgeting can be gained by providing people with a tool to perform these micro movements. The accessory of the present invention can enable people to do so, and in turn reduce the stigma attached to these types of fidgeting movements. It is believed that the suppression of fidgeting can in turn be a distraction and therefore there is a benefit to allowing an outlet for micro movement to relieve the desire to fidget. There is a benefit of achieving movement in terms of improving circulation and promoting self-regulation (homeostasis).

[0035] The present spinning accessory has the benefit of facilitating fidgeting in a discreet manner, therefore allowing the body to self-regulate and improving overall health and wellbeing.

[0036] In addition, research has proven that fidgeting expels more energy than sitting still, and so can aid weight loss, particularly among inactive people. The spinning accessory of the present invention could therefore aid those who are generally inactive, e.g. due to health conditions or due to a more sedentary lifestyle; the spinning accessory provides an accessible and straightforward route for these people to increase their normal level of activity and energy expenditure. The spinning accessory can be used to burn calories, even when sitting watching television or listening to music or a podcast, for example, and can be used even by those who are relatively frail or immobile.

[0037] The accessory is beneficial in that the sensory feedback can be primarily or solely haptic. Although the accessory may optionally be designed to provide aural and / or visual feedback, this is not essential. Therefore the accessory can be more discreet and able to be used without distracting other people nearby. In one embodiment, the accessory may be almost silent in use, thereby having the benefit of not distracting the user or others. In one embodiment, the housing is opaque, such that the orbiting bodies cannot be seen in use. This makes the accessory less visual, and therefore less distracting to the user and others nearby. The accessory can be used as an outlet for movement at any time, and in any environment, without causing distraction to the user or those around them. The accessory can be “gamified” by including sensors; this then allows for the use of the accessory to be monitored and use statistics can be fed back to the user. The use of the accessory to a pre-defined level (e.g. total number of rotations, use on consecutive days, reaching a required number of separate uses per day) can then unlock rewards or provide other positive feedback to the user. The accessory may be provided in combination with a computer implemented application (“app”). This enables the accessory to be used in a goal- driven way and can create a competition or game element. The accessory may receive data from sensors, may optionally process the data using a processor, and may communicate data back to the user, e.g. via an app.

[0038] The accessory thus has the ability for use as a toy or game experience, but also has the ability for use in relation to improving concentration, as well as the potential for use in sports and both mental and physical health related activities.

[0039] There has also been research into neuroplasticity and how the brain can change. It has been proven that people who have brain injuries can, by following certain exercises, encourage undamaged neural pathways to open. It is likewise known that as an individual develops into either a left- or right- handed person, neural pathways are slowly shut down. However, with training increased brain connections can be made and this is seen in, for example, professional two-handed piano players.

[0040] The present inventor has recognised that by using the spinning accessory of the invention in combination with another exercise, bi-manual training can be carried out to achieve various health and wellbeing benefits. Thus the spinning accessory of the invention can be used in brain training e.g. to improve concentration or co-ordination, or to strengthen the ‘weak’ side of an individual to compensate for left- or right- hand side dominance, or to reduce the effects or progression of age-related brain deterioration, or to assist with recovery from brain injury.

[0041] By using the spinning accessory of the invention on one finger or thumb whilst performing an exercise task, bi-manual interference occurs. In general this occurs when two limbs must be moved along different trajectories and conduct different task parameters. It is, in particular, foreseen that the user rotates the accessory on a finger or thumb of one hand and carries out a different activity with the other hand, e.g. tracing a path with a finger. Bi-manual training can aid development in children and can assist with co-ordination and support strong brain function in adults and the elderly. Bi-manual co-ordination also plays a major role amongst musicians and sports people, who may need to exhibit a greater ability to perform two-handed or two-footed than average individuals. It is believed that bi-manual training enables the brain to fire neurons that would not necessarily be fired normally, due to left- or right-hand dominance. This training will enable a greater use of the brain, which can aid individuals in brain growth / training or as the brain starts to deteriorate due to age; it may also be beneficial when recovering from brain injury.

[0042] The invention provides, in a second aspect, a method of bi-manual training for an individual, the method comprising: providing a spinning accessory according to the first aspect; and locating the accessory on a finger or thumb of the individual via the central aperture; and then simultaneously: rotating the accessory by movement of the finger or thumb of the individual, to cause the orbiting bodies to move around the closed loop circuit; and carrying out an exercise task involving the movement of another body part of the individual.

[0043] In one embodiment, the accessory is located, via the central aperture, on a finger or thumb of the individual (i.e. a first hand of the individual is used), and the exercise task involves the use of the individual’s other hand.

[0044] In one embodiment, for example, the exercise task is lifting weights with the other hand. Less strenuous exercise tasks can also be contemplated, e.g. head tapping or stomach rubbing. It may be preferred that the task involves a micro movement with the other hand, such as rotating the other hand in the opposite direction to the hand with the accessory, or tracing a path with a finger of the other hand.

[0045] In one embodiment, the user may have two spinning accessories according to the first aspect, one on a finger or thumb of their left hand and one on a finger or thumb of their right hand, and the two spinning accessories are rotated in opposite directions.

[0046] In one embodiment, the individual is a professional musician or a professional sportsperson. In another embodiment, the individual is an amateur musician or an amateur sportsperson.

[0047] In one embodiment, the method is carried out in a commercial setting, e.g. under the supervision of a physiotherapist or personal trainer or coach. The invention provides, in a third aspect, a method of improving brain function or reducing cognitive decline in a patient having a brain condition or disorder, the method comprising: providing a spinning accessory according to the first aspect; locating the accessory on a finger or thumb of the patient via the central aperture; and rotating the accessory by movement of the finger or thumb of the patient, to cause the orbiting bodies to move around the closed loop circuit.

[0048] The Dementia Society have suggested that fidget toys have been a useful distraction from the unpleasant effects of anxiety caused by the illness. Dementia patients have been understood to feel the need to walk, move and fidget to alleviate themselves.

[0049] In one embodiment, the patient has an age-related brain condition or disorder, such as dementia (including mild cognitive impairment (MCI)). In particular, the patient may have Parkinson’s disease, Alzheimer's disease, Lewy body dementia, vascular dementia, stroke, amyloidosis, Pick's disease, Lou Gehrig's disease, Huntington's disease, Creutzfeld-Jakob disease, or the like.

[0050] In one embodiment, the patient has brain damage, e.g. from an accident or from exposure to alcohol or drugs in the womb.

[0051] The invention provides, in a fourth aspect, a method of improving concentration in an individual, the method comprising: providing a spinning accessory according to the first aspect; locating the accessory on a finger or thumb of the individual via the central aperture; and rotating the accessory by movement of the finger or thumb of the individual to cause the orbiting bodies to move around the closed loop circuit.

[0052] In one embodiment, the individual has a neurological disorder or neurodiversity that can adversely impact concentration, such as ADHD (especially inattentive ADHD) or autism.

[0053] In one embodiment, the individual has a job that requires strong concentration skills, e.g. the individual may be a surgeon or other medical professional, or a pilot or professional driver, or an air traffic controller. In one embodiment, the method is carried out in a commercial setting, e.g. under the supervision of a private medical specialist or consultant, or a physiotherapist, or a personal trainer or coach.

[0054] Detailed Description of the Invention

[0055] The accessory of the invention is designed to carry out micro movements with the finger or thumb of one hand, to overcome inertia. The device uses the intrinsic and extrinsic muscle groups found in the hand. The accessory of the invention can be used by an adult or a child on a finger or thumb. It will be appreciated by the skilled person that the dimensions of the accessory may be designed for use by a child or an adult, with children tending to have smaller hands than adults, and that gender may also influence the dimensions, with males tending to have larger hands than females.

[0056] The accessory of the invention includes an outer enclosed track which provides a closed loop circuit. A housing defines this outer enclosed track. The housing may be of single piece construction or may comprise two or more parts that fit together to define the outer enclosed track. In one embodiment, the housing includes at least a top part and a bottom part, and these may directly fit together to define the outer enclosed track (e.g. snap fit or press fit or bayonet connection). In another embodiment, a top part and a bottom part may be joined together via one or more connecting parts to define the outer enclosed track. It may, for example, be that the housing includes a top part and a bottom part, and these are joined together via a central connecting band to define the outer enclosed track. One or more connectors (e.g. clips) may alternatively or additionally be used to connect the top part and the bottom part.

[0057] The closed loop circuit may, in one embodiment, be circular but although a circle is a straightforward shape to use and gives rise to an accessory that is easy for an individual to use, the shape of the circuit is not limited to this shape. For example, the circuit may be oval or ellipse in shape. A symmetrically shaped circuit may be preferred for achieving balance and a good user experience. In one embodiment the circuit has no sharp corners (e.g. no acute angles); for example it may be a curved circuit. If there are angles present, it may be desired that these are obtuse or reflex angles, i.e. over 90 degrees; in one embodiment any angles are 120 degrees or more, such as 150 degrees or more.

[0058] The cross-sectional external shape of the housing may mirror that of the closed loop circuit, or it may be different. The skilled person will appreciate that it may be convenient to have a matching shape, but this is not essential; for example a circular circuit could be provided in a housing that had a hexagonal or octagonal cross section. In one embodiment, the housing is substantially toroidal, and preferably it has a ring torus shape, i.e. it is doughnut shaped.

[0059] The housing may be made from any suitable material. In one embodiment it is made from a polymer (plastic), or a metal or metal alloy. The housing may, for example, be cast or molded or 3D printed.

[0060] In one preferred embodiment, the housing includes an interior layer that extends over some, most or all of the surface of the enclosed track. In one embodiment, the interior layer comprises a top portion and a bottom portion. The top portion and bottom portion may, together, extend over some, most or all of the surface of the enclosed track. The interior layer may, in particular, be noise-dampening material. The noise-dampening material may, for example, be natural or synthetic rubber such as neoprene and / or EDPM. It is of course preferred that the noise-dampening material does not inhibit the free movement of the orbiting bodies. A material with a smooth surface may therefore be preferred.

[0061] However, in some alternative examples, the surface of the enclosed track can comprise a textured surface, said textured surface providing haptic feedback to the user as the orbiting bodies pass over the textured surface. It is therefore possible for a noise-dampening material to be chosen that has a non-smooth surface; for example a felt material.

[0062] In one preferred embodiment, the housing fully encloses the orbiting bodies. In one such embodiment, the housing is opaque, such that the orbiting bodies cannot be seen in use. This making the accessory less visual, and therefore less distracting to the user and others nearby. This therefore assists in the use of the accessory in an almost sub-conscious manner, e.g. whilst the user is carrying out another activity. This may therefore be preferred.

[0063] However in one optional example, the housing includes one or more windows to allow for visualisation of the orbiting bodies. This therefore adds a visual sensory element to the haptic sensory element. Additionally, the noise created by the orbiting bodies as they move around the closed loop circuit can change depending on whether the body is adjacent to a window or not, and therefore there is an additional aural sensory element.

[0064] In the present invention, the closed loop circuit extends around a central aperture. The central aperture is sized and shaped to receive a finger or thumb. It will be appreciated that this invention is mainly described with reference to the embodiment where the central aperture is sized and shaped to receive a finger, but it is straightforward for the skilled person to appreciate how the size of the aperture can be adapted for a thumb and likewise the use of the accessory by movement of a thumb instead of a finger can be understood and implemented.

[0065] The accessory should not include any components that are located to prevent or hinder the user from passing the distal end of their finger or thumb through the central aperture until the accessory is resting at a location along the length of the finger or thumb. In other words the shape and size of the accessory should be such that there is clear access through the central aperture. There should not be a handle or any other component restricting access to the central aperture.

[0066] In one embodiment, the central aperture is sized and shaped to rest on the knuckle of the user’s finger or thumb, i.e. the aperture is smaller than the user’s knuckle. Therefore in such embodiments, the accessory does not rest at the base of the finger or thumb like a traditional ring. It can be envisaged that the accessory could rest at other locations on the user’s finger or thumb. In use, the accessory could be located at a range of locations on the user’s finger or thumb based on what the user finds comfortable.

[0067] In one embodiment, the central aperture has a diameter of from 5mm to 50mm, or from 10mm to 30mm; preferably from 10mm to 25mm, e.g. from 12mm to 20mm. It may suitably be that the central aperture has a diameter of from 12mm to 22mm or from 14mm to 20mm.

[0068] The central aperture may have any suitable length, taking into account that the accessory is intended to rest on a user’s finger or thumb and the central aperture therefore should have a length less than the length of that finger or thumb. In one embodiment, the central aperture has a length of from 5mm to 30mm, preferably from 10mm to 20mm, more preferably from 10mm to 15mm. Such a length of aperture ensures that there is sufficient contact between the accessory and the user’s finger or thumb, but that the accessory is comfortable to wear on the finger or thumb and can be readily manoeuvred.

[0069] In one embodiment, the length of the central aperture equals the maximum depth of the housing.

[0070] The housing may have any suitable maximum width or outer diameter. It will be appreciated that the housing should be large enough to provide a feeling of substance on the user’s finger or thumb, but small enough that the accessory is comfortable to wear on the finger or thumb and can be readily manoeuvred. In one embodiment, the outer diameter of the housing is from 15mm to 100mm, or from 20mm to 75mm; preferably from 30mm to 60mm, e.g. from 40mm to 50mm.

[0071] The accessory of the invention includes one or more orbiting bodies that are housed within the enclosed track and that can freely move around the closed loop circuit. The number of orbiting bodies may, for example, be from 1 to 30 or from 1 to 20, or from 1 to 10.

[0072] The one or more orbiting bodies provide haptic feedback to the user, with the weight moving round the closed loop circuit providing non-visual sensory feedback. The haptic feedback encourages the user to rotate the device and cause continuing movement thereby encouraging the user to perform micro movements. The importance of the non-visual sensory feedback caused by movement round the closed loop circuit is that it is not distracting to the user. This means that the user can have the benefit of the micro movements but can still concentrate on the task that they are doing, for example working at a desk, on a phone call, in a lecture, watching television.

[0073] In one embodiment, the accessory of the invention includes a plurality of orbiting bodies that are housed within the enclosed track and that can freely move around the closed loop circuit. Therefore in one embodiment there are two or more orbiting bodies, preferably three or more orbiting bodies. The use of a plurality of orbiting bodies enhances the haptic feedback to the user. The number of orbiting bodies may, for example, be from 2 to 30 or from 2 to 20, preferably from 2 to 15 or from 3 to 15, such as from 2 to 12 or from 3 to 12, more preferably from 3 to 10 or from 3 to 8. In one preferred embodiment, there are 3, 4, 5, 6, 7 or 8 balls provided as the orbiting bodies.

[0074] The use of a plurality of orbiting bodies (such as from 2 to 15, or from 3 to 10, such as from 3 to 8, orbiting bodies) within the closed loop circuit provides particularly beneficial and readily felt haptic feedback during use, as the multiple orbiting bodies move round that loop.

[0075] The use of multiple orbiting bodies is therefore preferred in order to ensure that enhanced haptic feedback is clearly felt by the user. However, if too many orbiting bodies are used there may be clashing, which is not desired. Therefore the use of from 2 to 15 or from 3 to 15 orbiting bodies, preferably from 2 to 12 or from 3 to 12, and more preferably from 3 to 10 or from 3 to 8, orbiting bodies is desired. In one preferred embodiment, there are 3, 4, 5, 6, 7 or 8 orbiting bodies, such as 4, 5 or 6 orbiting bodies. This ensures smooth movement without clashing whilst also having sufficient haptic feedback for the user. It can however also be envisaged that there is a single orbiting body which provides beneficial haptic feedback during use. In particular, by having a single extended orbiting body that extends around at least a fifth of the closed loop circuit, the movement of that extended orbiting body round the loop provides clear haptic feedback. In one embodiment, therefore, there is a single extended orbiting body that extends around from 20 to 80% of the circumference of the closed loop circuit, such as from 25% to 75%, preferably from 30% to 70% or from 33% to 67%, or from 35% to 65%, or from 40% to 60%. The shape of the extended orbiting body will correspond with the shape of the closed loop circuit. Therefore, for example, a curved elongate body in the form of an arc would be required for use within a circular closed loop circuit. The extended orbiting body may be solid or hollow. In one preferred embodiment it is solid, as this may assist with the haptic feedback provided during use. The extended orbiting body may, in one embodiment, be a sliding block.

[0076] In one embodiment it is preferred that the one or more orbiting bodies comprise either: (a) a plurality of orbiting bodies, such as from 2 to 30 or from 2 to 20, preferably from 2 to 15 or from 3 to 15, such as from 2 to 12 or from 3 to 12, more preferably from 3 to 10 or from 3 to 8 orbiting bodies; or (b) a single extended orbiting body (such as a sliding block) that extends around at least a fifth, preferably at least a quarter, e.g. at least a third, of the closed loop circuit.

[0077] In one embodiment, the orbiting bodies (the single extended orbiting body or the plurality of orbiting bodies in combination) extend around from 20 to 80% of the circumference of the closed loop circuit, such as from 25% to 75%, preferably from 30% to 70% or from 33% to 67%, or from 35% to 65%, or from 40% to 60%. By taking up this proportion of the closed loop, particularly good haptic feedback is achieved.

[0078] When there is a plurality of orbiting bodies, these bodies may in particular be spherical, e.g. they may be balls such as ball bearings. Ball bearings or other balls are advantageous as they have a small contact footprint with the track and minimal friction during use. The balls may be solid or hollow. In one preferred embodiment they are solid, as this may assist with the haptic feedback provided during use.

[0079] In one preferred embodiment, the plurality of orbiting bodies are balls and there may be from

[0080] 2 to 15 or from 3 to 15 balls, such as from 2 to 12 or from 3 to 12, and more preferably from

[0081] 3 to 10 balls, especially from 3 to 8 balls, e.g. 4, 5 or 6 balls, and the balls are suitably solid and may be formed from metal or metal alloy. The invention is, however, not limited to the use of ball bearings or other balls, as the skilled user will appreciate that other orbiting bodies may be used. Any component that can freely move around the track would offer a suitable alternative. The skilled person will appreciate that for example, sliding blocks (which may, for example, be cube or cuboid in shape) could be provided as the orbiting bodies.

[0082] The orbiting bodies may be made of any suitable material but may suitably be metal or metal alloy. This is preferred in terms of providing bodies that have sufficient weight such that a good user experience is achieved in terms of haptic feedback.

[0083] In a preferred embodiment the orbiting bodies are tungsten balls or steel balls, as the weight of these balls will improve the haptic feedback felt by the user. A single extended tungsten or steel body can also be contemplated, e.g. in the form of a sliding block.

[0084] In one embodiment, the orbiting bodies each have a width or diameter substantially similar to the width or diameter of the closed loop circuit, e.g. the width or diameter of the orbiting body may be 75% to 100%, or 85% to 100%, or 90% to 100% of the width or diameter of the closed loop circuit. This ensures that movement is primarily about the track of the closed loop circuit, rather than vertical movement that could cause rattling, which may be undesirable.

[0085] One suitable example of orbiting bodies is balls, e.g. ball bearings, with diameters from 3mm to 10mm, especially from 4mm to 8mm, or from 5mm to 7mm. In one exemplary embodiment, the accessory includes from 2 to 15 ball bearings, such as from 3 to 10 ball bearings, preferably from 3 to 8 ball bearings, each with diameters from 4mm to 8mm, such as 5mm or 6mm or 7mm diameter. A single extended orbiting body with a width of from 3mm to 10mm, especially from 4mm to 8mm, or from 5mm to 7mm can also be contemplated.

[0086] In some preferred embodiments, the orbiting bodies may have a smooth surface. This can make use of the accessory quieter, therefore making the accessory more discreet and unobtrusive, and less distracting to the user and others nearby.

[0087] However, in some examples of the present invention the orbiting bodies may have a textured surface. This can provide feedback as the body moves round the closed loop circuit. The textured surface may, for example, comprise bumps, grooves, or a textured finish. As noted above, the orbiting bodies preferably partly but not completely fill the circumference of the closed loop circuit. It will be appreciated that if the closed loop circuit is completely full then there will not be a good user experience in terms of the orbiting bodies moving round the circuit in use. It is preferred that the orbiting bodies take up from 20 to 80% of the circumference of the closed loop circuit, such as from 25% to 75%, preferably from 30% to 70% or from 33% to 67%. This can, for example, be calculated when considering the combined diameter of the orbiting bodies (e.g. 5 ball bearings each having a 6mm diameter = 30mm) as a proportion of the total circumference of the closed loop circuit, or can be determined based on the overall length of the single extended orbiting body. The length is an arc length when the extended orbiting body (e.g. sliding block) is curved.

[0088] The accessory of the invention is intended to provide haptic feedback to the user and therefore the weight of the accessory can assist with the user experience. If the accessory is too light there is insufficient feedback, but if it is too heavy it is challenging to use easily in a one- handed manner. The accessory may suitably weigh from 5g to 40g or from 5g to 35g, or from 5g to 30g; in one embodiment from 8g to 35g, and preferably from 10g to 30g, such as from 10g to 25g or from 10g to 20g. In some embodiments, the weight may be from 12g to 22g, or from 14g to 20g.

[0089] In some embodiments the accessory further comprises one or more sensors for detecting movement of the plurality of orbiting bodies around the closed loop circuit. The sensor may, for example, comprise one or more of a magnetic position sensor, light sensitive sensor or electrical sensor.

[0090] The use of a sensor allows for the use of the accessory to be monitored and for usage statistics to be fed back to the user. This may show how much the user has been moving. This feedback may encourage further use of the accessory and therefore lead to associated micro movements by the user.

[0091] The use of the accessory to a pre-defined level (e.g. total number of rotations, use on consecutive days, reaching a required number of separate uses per day) can then unlock rewards or provide other positive feedback to the user.

[0092] In one such embodiment, the accessory may further comprise a transmitter for transmitting data regarding movement of an orbiting body to a data receiver. The transmitter may comprise any known data transmission device, such as Bluetooth™, Wi-Fi™ or the like. In one embodiment, the accessory is provided with a GPS sensor to allow tracking of the accessory, e.g. to locate it if it is lost, or to link the use of the accessory to a location.

[0093] The accessory may be provided in combination with a computer implemented application (“app”). The app can provide an interface which can allow the user to be provided with statistics from their use of the accessory. This enables the accessory to be used in a goal- driven way and can create a competition or game element. This may motivate use of the accessory as a toy or game or may motivate use of the accessory as a health or wellbeing accessory or as sports / exercise kit. The computer implemented application may, for example, provide data which may be one or more of: usage statistics, rotation count, current rotation speed, average rotation speed, and / or battery life.

[0094] The optional digital additions for this invention provide users with feedback depending on their desired use of the accessory, regardless of whether the accessory is used in a sport, for medical / health benefits, or for fun / as a game. The accessory when provided with one or more sensors will enable the app to collect data to aid the user in their desired use and in staying focused on achieving their goals. This may motivate use and encourage competition.

[0095] It can be foreseen that challenges and exercises could be created to test the user’s coordination ability, adding an additional competition / game element.

[0096] In some embodiments the accessory may comprise a dynamo, and movement of the ball(s) around the circuit can power the dynamo. This can be used to power any electronic components. Alternatively, or additionally, the device may comprise a power source, which may be a rechargeable power source.

[0097] In some embodiments, the accessory may comprise a speaker. The speaker may, for example, be connected to a mobile phone or tablet device, or the like. Accordingly, the accessory may be used in combination with a computer implemented application (“app”) running on a mobile phone or tablet device that provides an audible component to the accessory’s use, e.g. it may provide verbal instructions, or it may play music to accompany use of the accessory. A transmitter for transmitting the audible component to the speaker may be provided. The transmitter may comprise any known data transmission device, such as Bluetooth™, Wi-Fi™ or the like. A game component of the use of the accessory could involve spinning the accessory in time to the music. The accessory may include haptic actuators. For example, these could be set to vibrate if the accessory is not used for a predefined period of time, or to vibrate as an alarm at a predefined time to remind the user to use the accessory.

[0098] The accessory may optionally be provided with an outer layer or “skin”. This may partly or fully cover the outside of the accessory. The outer layer may be removable and replaceable. The outer layer may be textured or have any other sensory feature. Optionally, the outer layer may have a colour or pattern or any other visual feature. This outer layer may allow for personalisation of the accessory. It may also allow for a competitive aspect to be introduced by providing certain outer layers that can only be obtained once certain challenges or goals have been completed or met. The outer layer, may, in one embodiment, be made from silicone or plastic (polymer). In one embodiment, the outer layer may be a silicone textured band that is interchangeable to enable customization. This textured outer layer also provides another form of sensory feedback to the user.

[0099] The accessory may be provided with a clip or other attachment device, so that it is easy to carry and may, for example, be clipped or a belt or bag when not in use.

[0100] In one embodiment, the accessory may be provided in small, medium and large sizes. The user may then select the most comfortable size for use on the intended finger or thumb.

[0101] In one non-limiting embodiment, the accessory may be provided in small, medium and large sizes as follows:

[0117] Detailed Description of the Drawings

[0118] The invention will now be further described, by way of example only, with reference to the accompanying drawings.

[0119] As noted above, the invention provides a spinning accessory for use by an adult or child on a finger or thumb, the accessory comprising:

[0120] • a housing defining an outer enclosed track which provides a closed loop circuit that extends around a central aperture; and

[0121] • one or more orbiting bodies that are housed within the enclosed track and that can freely move around the closed loop circuit; wherein the central aperture is sized and shaped to receive a finger or thumb, and whereby rotation of the housing causes the orbiting bodies to move around the closed loop circuit.

[0122] Figure la shows a schematic view of an accessory 110 according to an embodiment of the present invention. The accessory is a spinning sensory accessory. The accessory comprises a substantially torus shaped housing 111 defining an outer enclosed track which provides a closed loop circuit 116 that extends around a central aperture 113. The housing 111 can be worn on a finger or thumb of a user, with the user’s finger or thumb being located within central aperture 113. The housing 111 is broadly divided into an upper part 112 and lower part 114. The two parts snap together to form the housing. Each part 112, 114 is substantially semi-circular in cross-section such that when combined they form a hollow track 116 within.

[0123] Located within the hollow track 116 is one or more balls 120. Each ball is typically a metal ball bearing or the like. Each ball is sized relative to the hollow 116 to allow it to freely move around the closed loop circuit.

[0124] Alternatively an extended orbiting body may be used, e.g. in the form of a sliding arc-shaped block, which is sized to freely move around the closed loop circuit.

[0125] Figure lb shows the accessory 110 with the upper surface 112 removed such that the relative position of a ball 120 can be seen.

[0126] Figures 2a to 2c show an alternative embodiment where windows 230 are provided. The accessory 210 comprises a substantially torus shaped housing 211 defining an outer enclosed track which provides a closed loop circuit 216 that extends around a central aperture 213, as described above. The housing is comprised of upper part 212 and lower part 214. These two parts can snap fit together using connectors 222, 224. In contrast to the embodiment of Figure 1, in this embodiment one or more windows 230 are provided on an outer surface of the housing 211. These windows 230 allow for visualisation of the orbiting body / balls 220 on the closed loop circuit 216 within the housing 211. This is shown in Figure 2b, where a ball 220 is shown located adjacent to a window 230 in the lower part 214 of the accessory. The effect of windows 230 allows the user to see the position of the orbiting body / balls 220 in the closed loop circuit 216 and adds a visual sensory element to the overall experience. Additionally, by providing windows the noise created by the orbiting body / balls 220 as they pass around the circuit 216 changes depending on whether the ball is in front of the window 230 or not.

[0127] Figures 3a to 3d show another embodiment of the present invention in which a total of five balls 320, 322, 323, 324, 325 are provided. It can be appreciated that whilst shown with a total of five balls, different amounts of total balls may be used, for example 3, 4, 6 or 7. A single extended orbiting body e.g. in the form of a sliding arc-shaped block, that takes up a comparable or equivalent proportion of the closed loop circuit to the multiple balls could be used instead. The accessory 310 comprises a substantially torus shaped housing 311 defining an outer enclosed track which provides a closed loop circuit 316 that extends around a central aperture 313, as described above. The housing is comprised of upper part 312 and lower part 314 and central band 330. The two parts 312, 314 snap together with central band 330 to form the housing 311. Inner layer 331 is provided within the housing 311 and this is made from noisedampening material such as rubber.

[0128] The additional features of this Figure 3 embodiment (multiple balls, central band, inner layer) may each independently be used in other illustrated embodiments or may be used in combination.

[0129] Figure 4 shows the accessory 110 in use 400. It is shown with the device of Figure 1, but any embodiment can be used in a similar way, e.g. the accessory 210 or 310 could be used in the same manner. The ring shape of the accessory with its central aperture allows the user to place the accessory on their finger, at around the location of their knuckle, and rotate their finger, or move their finger back and forth. Such motion causes the orbiting body / balls to move within the closed loop circuit. This causes the centre of mass of the accessory to shift due to the movement of the balls, which gives haptic feedback to the user.

[0130] In a further embodiment as shown in Figure 5, the device may also comprise electrical components. In this example the accessory 510 further comprises one or more sensors 530 for detecting movement of the balls 520 within the closed loop circuit. The sensor may comprise one or more of a magnetic position sensor, light sensitive sensor or electrical sensor. In all cases the sensor is intended to determine movement of the balls as they move within the closed loop circuit.

[0131] An accelerometer or gyroscope may also be used to allow the relative orientation of the device 510 to be determined when worn by a user.

[0132] In addition to the sensor 530, a transmitter 540 is provided, for transmitting data regarding movement of the orbiting body / balls 520 to a data receiver 550. The transmitter is typically a Bluetooth™ transmitter, due to the low power requirements, but it can be appreciated that any known data transmission device, such as a Wi-Fi™ transmission device or the like, may be used.

[0133] The receiver may, in one embodiment, be a mobile phone or tablet device, or the like. Accordingly, the accessory may be used in combination with a computer implemented application (“app”) running on a mobile phone or tablet device that is the receiver 550. The application receives the data transmitted by the transmitter 540 and allows for the determination of, for example, one or more of: usage statistics, rotation count, current rotation speed, average rotation speed, or battery life.

[0134] By collating this information, feedback can be given to the user. This may include information on the extent of use of the accessory and can measure achievements against preset goals, e.g. number of uses, consecutive uses, number of rotations.

[0135] It will be appreciated that the use of a computer implemented application can allow for the overall user experience to be gamified, with targets given for the user, such as a number of reps per minute, or overall throughout the day, and rewards being provided for meeting these targets. It can also be envisaged that league tables or head-to-head competitions could be set up with other users.

[0136] The feedback may also include tips such as how to move the accessory (e.g. by movement of the user’s finger, hand or arm) to provide for smoother or faster motion of the orbiting body / balls around the circuit. This feedback and tips may be provided in response to data received by a gyroscope and / or accelerometer or the like.

[0137] In some embodiments the accessory may comprise a dynamo, and movement of the balls around the circuit can power the dynamo. This can be used to power any electronic components. Alternatively, or additionally, the device may comprise a power source, which may be a rechargeable power source.

[0138] Figures 6a to 6d show another embodiment of the present invention in which a total of five balls 620, 622, 624, 626, 628 are provided. It can be appreciated that whilst shown with a total of five balls, different amounts of total balls may be used, for example 3 or 4 or 6 or 7 balls. A single extended orbiting body e.g. in the form of a sliding arc-shaped block, that takes up a comparable proportion of the closed loop circuit to the multiple balls could be used instead.

[0139] The accessory 610 comprises a substantially torus shaped housing 611 defining an outer enclosed track which provides a closed loop circuit 616 that extends around a central aperture 613, as described above. The housing is comprised of upper part 612 and lower part 614. The two parts 612, 614 snap together to form the housing 611. Inner layer 631a and 631b is provided within the housing 611 and this is made from noisedampening material such as rubber.

[0140] The accessory 610 is provided with an outer silicone layer 670 which is a removable and replaceable silicone textured band. This outer layer is interchangeable to enable customization. This textured outer layer also provides another form of sensory feedback to the user.
