[0002] Description

[0003] The present invention relates to a device for controlling a multimedia playback device according to the preamble of claim 1.

[0004] From US patent 2014 / 0152899A, a device for controlling a multimedia playback device is known according to the preamble of claim 1.

[0005] The object of the invention is to improve the known device for controlling a multimedia playback device.

[0006] The problem is solved by the features of the independent claims. Preferred further developments are the subject of the dependent claims.

[0007] According to one aspect of the invention, a device for controlling a multimedia playback device comprises a base body spanned in a longitudinal direction, a transverse direction transverse to the longitudinal direction, and a vertical direction transverse to the longitudinal direction and transverse to the transverse direction, with an input field arranged on the top side when viewed in the vertical direction and a foot arranged opposite the input field when viewed in the vertical direction for placing the base body on a base surface, wherein the size of the base body in the longitudinal direction is at least three times larger than in the transverse direction, so that the base body can be grasped by a user about a longitudinal axis oriented in the longitudinal direction in such a way that the base body is oriented with a rear side facing the user when viewed in the longitudinal direction.

[0008] According to the invention, in the device for controlling a multimedia playback device, a cross-section of the base body, viewed in the vertical direction, is formed that increases in size from the input field towards the base, in the opposite direction to the vertical direction.

[0009] The proposed device is based on the premise that conventional devices for controlling multimedia playback equipment are designed to be as rounded and edgeless as possible to be ergonomically comfortable for the average user and easy to operate. However, these designs are not always optimal for people with physical limitations who have difficulty holding such a device steady due to tremors or impaired fine motor skills. In many households, people with physical limitations live with other family members or housemates who often wish to use such devices from a relaxed, seated position. The challenge, therefore, is to provide a device for controlling multimedia playback equipment that meets the different needs of both user groups.Such a device must therefore be both handy and easy to use, while also being stable on a table to ensure safe and efficient use for people with physical limitations. The specified device for controlling a multimedia playback device addresses this need through its increasing cross-section, which widens from the input field towards the base, thus increasing in width and / or weight towards the bottom, significantly improving stability. This stable base minimizes the device's tendency to slip on a table surface, which is particularly important for people with physical limitations who wish to, or even must, operate the device while lying on the table.Thanks to this stable base, users can operate the input fields safely and precisely without the device easily tipping or slipping. This facilitates operation and reduces the force required to press the buttons.

[0010] At the same time, the device remains manageable enough for the average user to be used in its original intended purpose. Despite the increased stability and wider base, the device is designed to remain comfortable to hold and easy to operate. This ensures that the device meets the needs of both people with physical limitations and those of average users who wish to use it from a relaxed seated position.

[0011] Another problem with conventional devices is their tendency to easily fall off the table if accidentally bumped, for example, during room cleaning. This can also happen if they are carelessly set down or accidentally brushed against. Such falls often result in damage that shortens the lifespan of conventional devices and increases the need for frequent repairs or replacements. The specific cross-sectional distribution of the device described here for controlling a multimedia playback device significantly reduces the risk of such falls. Because the main body of the remote control is progressively wider from the input area towards the base, its stability is considerably improved. This design ensures that the device becomes wider and / or heavier towards the bottom, thus providing greater stability on a table surface.This increased stability ensures that the remote control remains firmly in place even if accidentally bumped, for example during cleaning or other household activities, and is less likely to tip over or fall off the table. The stable base also prevents the remote from sliding around when not in use, helping to keep the room tidy. As a result, the device remains functional for longer, even after such falls, extending its lifespan and reducing the need for frequent repairs or replacements.

[0012] In addition to increased stability, this design also offers significant advantages in terms of ergonomics and handling. The shape ensures a lower center of gravity, making the device more stable and easier to grip. This is particularly beneficial for individuals with limited hand strength or mobility, as the upper, narrower part of the device is ergonomically shaped for a comfortable grip.

[0013] In addition to increased stability, this design also offers advantages in terms of ergonomics and handling. The increasing cross-section from the keypad towards the base lowers the remote's center of gravity. A lower center of gravity improves the remote's stability, especially when held in the hand. For people with shaky hands or limited fine motor skills, this means the remote is less prone to wobbling. A lower center of gravity ensures more controlled and stable movements, increasing precision when pressing the buttons. This not only makes the remote easier to use but also reduces the likelihood of accidentally dropping it. Overall, this ergonomic improvement makes using the remote safer and more comfortable for all users, particularly those with physical limitations.

[0014] In a further development of the specified device, the increase in the cross-section seen in the vertical direction is at least 0.05 cm. 2 , preferably at least 0.1 cm 2 , per centimeter of height. In this way, an optimal compromise between haptics / ergonomics and stability is achieved, because the specified range of values ​​makes it possible to meet both the user's needs in terms of comfort and handling as well as the requirements for the stability and sturdiness of the remote control.

[0015] In another embodiment of the device, the center of gravity of the cross-section shifts towards the rear as the height decreases. This creates a triangular cross-section along the transverse axis, with the wider side facing forward and resting in the hand. This not only makes gripping and holding easier, especially for people with differently sized hands or limited hand strength, but also stabilizes the operation of the input field for these users. Furthermore, shifting the center of gravity from the front to the back contributes to the device's stability when placed on a surface. The forward shift of the center of gravity allows the user to pull the device closer to them over the edge of the table without it falling off.This is particularly advantageous for people with physical limitations who may be unable to hold the remote control but still want the input field as close as possible. Furthermore, the resulting inclined input field allows for a more comfortable and natural hand position when operating the remote control. This reduces strain on the wrists and fingers, which is especially beneficial for people with limited mobility or hand strength. In a further refinement of the device, the input field can be inclined towards the base around a transverse axis at an angle such that the vertical distance between the input field and the base is smaller on the rear side (viewed longitudinally) than on the front side (viewed longitudinally).In this way, the aforementioned shift in the center of gravity of the area can be implemented in a simple manner.

[0016] In a further embodiment of the specified device, a base side of the base body containing the foot and a top side of the base body containing the input field are connected to each other via a shell side which is oriented with respect to the vertical direction at a mean angle of attack between 0° and arctan ( ) , in particular is inclined at 10°, where a0 is the extent of the base body in the longitudinal direction, bo is the extent of the base body in the transverse direction and h is the maximum height of the base body.

[0017] This design ensures that, regardless of the specific angle of attack of the outer surface, there is always sufficient space for the input field. By selecting an angle of attack within the defined range, it is guaranteed that the cover surface, on which the input field is located, always offers an adequate area. This is particularly important for accommodating all necessary operating functions and creating a user-friendly interface.

[0018] Precisely defining the angle of attack within the specified range allows for flexible design of the base body, ensuring both stability and functionality. In particular, an angle of attack of approximately 10° guarantees sufficient space for the input field and allows for the implementation of the aforementioned considerations. These design decisions ensure that the device remains both aesthetically pleasing and functional, regardless of how the angle of attack is varied within the permissible range.

[0019] In a further embodiment of the device described, at least one anti-slip element, preferably at least three anti-slip elements, can be provided at the base of the main body. This further increases the stability of the device on the surface, such as a table.

[0020] In a further development of the specified device, the basic body is constructed in multiple parts, comprising a receiving tray with the base and a remote control with the input field, which is removable and inserted into the receiving tray.

[0021] A key advantage of this multi-part design of the base, which includes a cradle with a base and a remote control with an input panel that is removable and inserted into the cradle, lies in the versatility and flexibility of this solution. This design allows a conventional remote control to be integrated into the cradle, thus utilizing the fundamental concept of increased stability and improved ergonomics.

[0022] The cradle provides a stable base, complemented by its wide, flat foot. This ensures the remote control sits securely on any surface and won't easily slip or tip over. Users can remove the remote from the cradle and use it separately as needed, offering a high degree of flexibility. This feature is particularly advantageous because it allows the remote to be used both in a stable position on a table and on the go. Furthermore, the cradle is compatible with various standard remote controls, as long as they fit. This means existing remotes can be integrated into the system without the need to purchase special or new ones. This saves costs and facilitates customization to individual user needs and preferences.

[0023] The multi-part design allows the remote control and the cradle to be cleaned and maintained separately, improving hygiene and extending the lifespan of the components. Additionally, the modular design offers the option of equipping the remote control with extra functional elements that can be housed in the cradle. This further enhances the device's functionality and versatility.

[0024] In a preferred embodiment of the device, the base is flat. The flat base ensures that the remote control stands securely and stably on various surfaces, minimizing the risk of tipping or slipping. This is particularly important when the device is placed on smooth or slightly inclined surfaces such as tables or countertops.

[0025] The flat design of the base ensures that the weight of the device is evenly distributed, resulting in better balance and increased stability. This is because all parts of the contact surface are subjected to the same load. A flat base also makes it quick and easy to place the remote control down. Users don't need to worry about correct positioning, as the device remains stable and secure in any position.

[0026] Furthermore, the even and stable contact surface of the flat base reduces the risk of the device tipping over and being damaged by accidental bumps or minor impacts. This contributes to the device's longevity and reduces the need for frequent repairs or replacements. Overall, a flat base offers significant advantages that improve the stability, ease of use, and durability of the device.

[0027] In this advanced design, the transition between the base and the outer surface of the main body is acute-angled. This acute angle eliminates gaps between the support surface and the remote control, which could potentially cause the remote to tilt unintentionally during operation. This is particularly advantageous for users with shaky hands or limited fine motor skills who require a more stable and secure operating platform.

[0028] The properties, features, and advantages of this invention described above, as well as the manner in which they are achieved, will become clearer in connection with the following description of the exemplary embodiments, which are explained in more detail in conjunction with the drawings. The drawings show:

[0030] Fig. 2 shows a front view of the remote control from Fig. 1.

[0031] Fig. 3 shows a rear view of the remote control from Fig. 1.

[0032] Fig. 4 shows a side view of the remote control from Fig. 1.

[0033] Fig. 5 shows a perspective view of an alternative remote control in a receiving tray.

[0034] Fig. 6 shows a side view of the remote control from Fig. 5 in the receiver cradle. In the figures, identical technical elements are labelled with the same reference symbols and described only once. The figures are purely schematic and, in particular, do not represent the actual geometric relationships.

[0035] Reference is made to Figures 1 to 4, which show a device 2 for controlling a multimedia playback device (not shown in detail) in a perspective view, a front view, a rear view, and a side view. The device 2 is arranged in a space defined by a longitudinal direction 4, a transverse direction 6 perpendicular to the longitudinal direction 4, and a vertical direction 8 perpendicular to the longitudinal direction 4 and perpendicular to the transverse direction 6.

[0036] A multimedia playback device is an electronic device capable of playing various types of media content, such as videos, music, photos, and digital presentations. Examples of such devices include televisions, Blu-ray players, streaming boxes, home theater systems, computers, and mobile devices like tablets and smartphones. These devices allow users to access a wide variety of media content and enjoy it in a convenient and interactive way.

[0037] The basic functionality of a multimedia playback device comprises several main components. First, the menu navigation is crucial for the user experience. A graphical user interface (GUI) allows a user to navigate through various menus to select media content, adjust settings, and control functions. This is done via the device.

[0038] Another important aspect is media selection. Users can choose from a variety of media sources, such as internal storage, external hard drives, network storage, or online streaming services. Media selection is usually done via structured menus that sort content into categories like movies, music, or photos. Additionally, multimedia playback devices typically offer the ability to create and manage playlists, allowing for personalized media use. Features like pause, rewind, fast forward, and playback speed adjustment are also standard to ensure flexible and convenient use.

[0039] In the present embodiment, the device 2 functions directly as a remote control 10. An alternative embodiment in which the device 2 is designed as a multi-component device will be discussed in more detail later with reference to Figures 5 and 6.

[0040] The device 2 comprises a base body 12 with an input field arranged on the top surface 14 when viewed in the vertical direction 8. The input field is flexible in its design. Examples include a touchpad, a capacitive or resistive touchscreen, mechanical buttons, or a haptic feedback system, so that the remote control 10 can be adapted to different user preferences and technological requirements.

[0041] In the present embodiment, the input field is designed as a keypad. It comprises a lower key area 16 (viewed in the longitudinal direction 4), an upper key area 18, and a control pad 20 arranged between them. The two key areas 16 and 18 comprise keys 22, not all of which are labeled with their own reference symbols in the figures for the sake of clarity, and which each form a more or less regular grid. The control pad 20, in turn, is formed in the present embodiment from a ring 24, in the center of which another key 22 is arranged.

[0042] The arrangement of the keypads 16 and 18, the directional pad 20, and the buttons 22 within keypads 16 and 18 is designed to allow intuitive and efficient operation of the device's various multimedia playback functions. The lower keypad area 16 and the directional pad 20, for example, can be used for multimedia-specific controls. These include functions such as selecting multimedia playback, browsing media libraries, and choosing the multimedia playback application. For this purpose, the directional pad 20 is enlarged and positioned for easy access, enabling quick navigation and selection.

[0043] The upper button area 18, on the other hand, can be primarily intended for device control. This includes basic functions such as switching the device on and off and selecting input sources. This arrangement ensures that the most important control functions are always readily accessible. However, it should be noted that a strict separation between the functions of button areas 16, 18, and 20 is not necessary. For example, volume control could also be located in the lower button area 16. Depending on user preference and the specific application of the remote control 10, the buttons can be individually assigned and configured to ensure optimal usability. This offers a high degree of flexibility and allows the remote control 10 to be adapted to the specific needs and requirements of the users.

[0044] Device 2 is to be designed so that remote control 10 can be used by the widest possible range of people. This presents a significant challenge, which consists of taking into account the different needs and abilities of users of different age groups and with different physical limitations, while simultaneously ensuring intuitive and efficient operation.

[0045] One of the first challenges is considering age differences. Children need a remote control that is easy to use and doesn't have complicated functions. A clear layout of the buttons and intuitive symbols are important to ensure ease of use. Furthermore, the device should be robust and safe to withstand drops or rough handling.

[0046] Adult users often have higher expectations for the functionality of a remote control. They expect a wide range of functions that are easily and quickly accessible. Clear menu navigation and a good balance between the number of buttons (22) and their functions are crucial for efficient operation.

[0047] Older people, on the other hand, have different needs. For them, it's important to integrate large, easily readable buttons (22) and a high-contrast display. The buttons (22) should be easy to press to allow operation even with limited hand strength. Furthermore, a simple and intuitive user interface makes using the remote control (10) easier.

[0048] For people with physical limitations, such as those with impaired fine motor skills or shaky hands, a stable and non-slip remote control 10 is essential. A flat and wide base 26 can help to securely place the device 2 on a surface. Ergonomically shaped grips and tactile feedback from the buttons are also important to facilitate operation.

[0049] Furthermore, universal design principles must be observed to make the device accessible to people with different abilities. These include clear and unambiguous symbols, acoustic and visual feedback, and the ability to customize the function of the 22 buttons. A good balance between haptic and visual feedback is also important to ensure barrier-free use.

[0050] These challenges are addressed, firstly, by the fact that the base body 12 has the aforementioned foot 26, positioned opposite the input fields 16, 18, 20 in the vertical direction 8, for placing the base body on a surface. This foot 26 is designed to be as flat as possible, thus ensuring a stable base for the device 2 on various surfaces. This minimizes the risk of tipping or slipping, especially when the device 2 is placed on smooth or slightly inclined surfaces such as tables or worktops. The uniform contact surface helps to distribute the weight of the device 2 evenly, which increases its balance and stability. This stability is particularly important for people with physical limitations who need to operate the remote control 10 safely on a surface without it slipping or tipping over.

[0051] The flat design of the base 26 also facilitates the simple and straightforward handling of the remote control 10. Users do not need to worry about correct positioning, as the device 2 stands stably and securely in any position. This is particularly advantageous for elderly people and children who might have difficulty holding or positioning the remote control 10 securely.

[0052] Another advantage of the flat design of the base 26 is the reduction of damage. When the device 2 rests stably on a surface, it is less prone to accidental tipping and falling. This contributes to the device 2's longevity and reduces the need for frequent repairs or replacements. Furthermore, the stable base prevents the remote control 10 from wobbling or moving when buttons are pressed, significantly improving usability and ease of use.

[0053] The longitudinal dimension 4 of the base body 12 is at least three times greater than its transverse dimension 6. This proportional design ensures that the base body 12 can be gripped by a user around a longitudinal axis 28 oriented in the longitudinal direction 4, which is indicated by a dashed line in Fig. 1, so that the back of the base body 12 is oriented towards the user in the longitudinal direction 4. This elongated shape makes the remote control 10 comfortable to hold and easy to use. It allows the user to grip the remote control 10 securely and easily access all buttons 22 and functions without having to constantly adjust their hand position.

[0054] A key aspect of the device 2 is that the cross-section of the base body 12, as viewed in or against the vertical direction 8, increases from the input field 16, 18, 20 towards the base 26. This means that a geometric longitudinal extent 30 of the device 2 in the longitudinal direction 4 and / or a geometric transverse extent 32 in the transverse direction 6 increases as one moves further downwards in the vertical direction 8.

[0055] This design makes the device 2 wider in the transverse direction 6 and / or longer in the longitudinal direction 4 when viewed from the opposite direction to the vertical direction 8, which offers several significant advantages. Firstly, the increasing width lowers the center of gravity of the device 2. This increases the stability of the device 2, as it is less likely to tip over when placed on a surface. This is particularly important for users with shaky hands or limited fine motor skills, as a more stable device 2 or remote control 10 is easier to operate.

[0056] Secondly, the enlarged base 26 provides a better contact surface, minimizing the risk of slipping. A wider or longer base 26 ensures that the device 2 stands firmly and securely on a table surface, even if it is slightly bumped. This contributes to safety and ease of use and prevents the remote control from accidentally falling off the table and being damaged.

[0057] Additionally, the increased downward extension makes the remote control easier to handle. Users can grip the remote securely and have a more stable base to lean on. This is particularly beneficial for the elderly and those with limited hand strength, as they need to hold the remote less tightly to operate it stably.

[0058] For optimal stability of the device 2, the increase in the cross-section seen in or against the vertical direction 8 should be at least 0.05 cm.2 , preferably at least 0.1 cm 2 , per centimeter of height. This specific increase ensures that the longitudinal dimension 30 and / or the transverse dimension 32 at the base 26 is sufficiently large for a stable support.

[0059] Furthermore, the individual cross-sectional surfaces of the device 2, viewed in or against the vertical direction, possess centroids 36 which shift towards the rear side (viewed in the longitudinal direction 4) with decreasing height in the vertical direction 8. In the figures, not all of these indicated centroids 36 are labelled with their own reference numeral. The shift is indicated in the figures by a dashed arrow 38. Specifically, the configuration of the centroids 36 means that the centroid 36 on the upper side (viewed in the vertical direction 10) is further away from the user than the centroid 36 on the underside (viewed in the vertical direction 10). This generates a torque that would cause the device 2 to tip downwards at the front (viewed in the longitudinal direction 4) if it were not held in place.

[0060] This design places the device's center of gravity on the upper keypad area 18. While this may take some getting used to for average users, it is manageable for them to hold the device 2 with slightly more effort at the rear (viewed in the longitudinal direction 4) in order to operate the remote control using the lower keypad 16 and the directional pad 20. However, this design offers a particular advantage for users with physical limitations who are able to hold the remote control. They are intuitively guided to hold the device 2 in the area of ​​the upper keypad area 18. This means that the upper keypad area 18 can be assigned functions specifically designed for this group of users, such as large, easily accessible buttons for basic functions like switching on and off, volume control, or selecting input sources.This arrangement significantly simplifies operation and ensures that the most important functions are always easily accessible.

[0061] Furthermore, in the device 2, the input field 16, 18, 20 is arranged inclined relative to the base 26 about a transverse axis 40 oriented in the transverse direction 6 at an angle of inclination 42 such that the vertical distance 44 in the vertical direction 8 between the input field 16, 18, 20 and the base 26 on the rear side (as viewed in the longitudinal direction 4) is smaller than the vertical distance 46 on the front side (as viewed in the longitudinal direction 4). This angle of inclination 42 offers several significant advantages.

[0062] A key advantage of this arrangement is the inclination of the input fields 16, 18, 20 towards the user when the device 2 is lying on a surface. This significantly improves the visibility of the input fields 16, 18, 20, as the user can see them at a clearly perceptible angle without having to lift the device 2. This is particularly helpful for elderly people or those with impaired vision, as it allows them to see the keys 22 and the ring 24 more easily.

[0063] Another important aspect is that the incident ceiling light is reflected less strongly from the input fields 16, 18, 20, thus reducing glare. This ensures a clearer view of the buttons 22 and the ring 24, thereby improving the usability of the device 2, especially in rooms where the light shines perpendicularly onto the device 2 from a light source. Additionally, the angled arrangement of the input fields 16, 18, 20 allows for more ergonomic handling. The user can operate the device 2 in a natural hand position without unnecessarily straining the wrist. This is particularly important for users with physical limitations who need to rest their wrist on a table. The angle of inclination 42 makes it easier for them to reach the input fields 16, 18, 20. This design facilitates access to the buttons 22 and the ring 24 and reduces fatigue during prolonged use, making operation more comfortable and less strenuous.

[0064] The inclination of the input field 16, 18, 20 about the transverse axis 40 causes the radius r of the inclination angle 42 to vary depending on the angular position 0 of the inclination angle 42. This means that the radius r at a height z seen in the vertical direction 8 and at an angular position 0 is influenced by the inclination angle 42.

[0065] The cross-sectional area A(0) through the base body 12 as a function of the angular position 0 can be described as follows: / where o is the angle of attack 48 at which the lateral surface 50 of the base body 12 is inclined to the vertical direction 10.

[0066] As a reminder, the basic idea of ​​device 2 is that the cross-sectional area of ​​the base body 12, viewed in or against the vertical direction, increases with decreasing height in the opposite direction. This increase in cross-sectional area is now considered along the circular path spanned by the angle of inclination 42. The increase in cross-sectional area as a function of the angular position 0 is described by the derivative of A(0) with respect to 0: This expression can be simplified as follows:

[0067] If we insert the value arctan into this formula The change in area becomes zero, which means that an extreme value is present. Therefore, the lateral surface should be inclined at an angle of attack o to the vertical direction 10, which is greater than this value but less than 90°.

[0068] In a further embodiment of the device 2, four anti-slip elements in the form of small anti-slip pads 52 are arranged in the corners of the base 26 of the main body 12. This arrangement is preferred because the anti-slip pads 52 can be easily replaced if they become contaminated. Alternatively, the entire base 26 of the main body 12 could also be provided with a non-slip coating to serve as the anti-slip element.

[0069] The specific placement of the anti-slip pads 52 in the corners offers several advantages. In the corners, the anti-slip pads 52 ensure an even distribution of the anti-slip properties across the entire area of ​​the base 26. This maximizes the stability of the device 2, especially on smooth or slightly inclined surfaces. Furthermore, the arrangement of the anti-slip pads 52 in the corners allows the base 26 of the main body 12 to stand securely even on slightly uneven surfaces, as the anti-slip pads 52 act independently and can adapt to the contours of the surface. Another advantage of this specific arrangement is ease of maintenance. In case of contamination or wear, the anti-slip pads 52 can be replaced individually without having to replace the entire base 26. This reduces maintenance costs and increases the service life of the device 2.Furthermore, the anti-slip pads 52 provide additional protection for the surface on which the device 2 is placed. They prevent scratches and other damage that could occur if the device 2 were moved. Finally, the base body 12 has an acute-angled transition 54 (i.e., at an edge) between the foot 26 and the outer surface 50. This ensures that the device 2 has the most secure hold possible and does not form any unwanted gaps where the device could wobble. The acute-angled transition minimizes the risk of the device 2 becoming unintentionally unstable during operation, especially by users with physical limitations, and ensures that it stands firmly and securely on a variety of surfaces. This significantly increases the stability and safety of the device 2 during use.

[0070] Finally, reference is made to Figs. 6 and 7, which show an alternative embodiment of the device 2, in which the base body 12 is constructed in multiple parts and includes a receiving tray 56 with the base 26 as well as the remote control 12 with the input field 16, 18, 20, which is removable and inserted into the receiving tray 56.

[0071] This design offers the advantage that the underside of the remote control 12 is decoupled from the implemented concept. The mounting bracket 56 holds the remote control 12 stably and securely in position, while the actual input fields 16, 18, 20 remain flexible and easily accessible. The mounting bracket 56 acts as a stabilizing element that encompasses the base 26, thus providing the benefits of a stable, non-slip construction without compromising the ergonomics and functionality of the remote control itself.

[0072] The mounting tray 56 further contributes to the stability of the entire device, as it can be constructed with any desired weight and securely fixes the remote control 12, which can then be more easily designed, thus preventing slippage or tipping. Decoupling the underside of the remote control from the implemented concept allows the advantages of the stable base to be utilized, while the remote control itself remains handy, ergonomic, and freely designable.
