Description

[0001] Assistance device, method of manufacturing an assistance device, and assistance program

[0002] Visual impairment, including blindness, causes several challenges during day-to-day activities for the affected subject, e.g., person. To provide assistance to the visually impaired, several assistance mechanisms for assisting the visually impaired are known from the prior art. For instance, walking sticks are commonly carried by people suffering from visual impairment to assist the respective person in detecting obstacles, hazards, walking paths, etc. Acoustic assistance devices to convey information acoustically rather than visually to the affected individuals, such as at pedestrian traffic lights, are also known from the prior art. Moreover, for instance, braille is used to provide information to the visually impaired in a variety of different situations and / or environments.

[0003] However, several deficiencies remain with the assistance mechanisms known from the prior art. For instance, at least some of the known assistance mechanisms have a relatively poor degree of user-friendliness. For instance, the known assistance mechanisms often require the respective user of the respective assistance mechanism to use one or both hands, e.g., such as to read Braille lettering and / or to hold a walking stick. Furthermore, the known assistance mechanisms often have a relatively low degree of reliability in assisting the user, which may, e.g., put the respective user at risk for accidents and / or may put the respective user in unpleasant situations. Furthermore, there is an overall need to improve the confidence of the visually impaired individual during day-to-day activities and / or to increase the individual's quality of life during use of a respective assistance mechanism.

[0004] Moreover, these deficiencies also apply to assistance devices for other applications, such as assistance devices for assisting users in situations in which visual perception or detection may be impaired, e.g., in dark environments and / or when one or more objects may be hidden and / or occluded from the user's vision.

[0005] The prior art has not, or at least not sufficiently, addressed one or more of the disadvantages mentioned above. Hence, it is an object of the present invention to provide an improved means of providing assistance to a user, e.g. the visually impaired, in particular by improving one or more of the above-mentioned disadvantages.

[0006] This object is achieved by an assistance device for assisting a user, e.g. a visually impaired user, defined by the features of claim 1. Variations and further developments are defined by the features of the dependent claims. The assistance device may include a support device configured to be worn on a head of the user. The assistance device may include at least one detection device attached to the support device. The detection device may be configured to detect at least one object in a vicinity of the user and generate data based on the detected object, while the user is wearing the assistance device. The assistance device may include at least one processor configured to determine a distance between the user and the object based on the data provided by the detection device. The processor may be attached to the support device. The assistance device may include at least one indication device configured to generate at least one signal which may be haptically and / or acoustically perceivable by the user to indicate the distance to the user. The indication device may be attached to the support device. The user is preferably a human. However, the user may alternatively be an animal.

[0007] The assistance device described herein provides an enhanced means, compared with assistance mechanisms known from the prior art, to assist a user, e.g. a visually impaired user, in day-to-day situations. Since the assistance device is head-worn and generally does not require the use of the user's hands, the assistance device described herein has a relatively high degree of user-friendliness and comfort. Furthermore, configuring the indication device to generate the haptically and / or acoustically perceivable signal to indicate the distance between the user and the object to the user may provide a relatively intuitive and / or reliable means of conveying information about the user's environment to the user.

[0008] Moreover, the assistance device may provide a monitoring means for monitoring the user's environment and guiding means for guiding the user while walking and wearing the assistance device, in particular by indicating, preferably continuously, to the user, by means of the indication device, that one or more objects are present in the vicinity of the user and a change in the distance between the one or more objects and the user as the user moves relative to the objects, e.g., as the user walks towards and / or past the objects. This may increase the user's confidence in day-day-to-day activities, in particular walking and / or running, and / or may increase the user's quality of life. Moreover, the assistance device goes beyond providing a mere warning function to the user that an object may be in the user's vicinity, e.g., in the user's path. Instead, the assistance device described herein may provide assistance for guiding the user past and / or around the object by providing information, preferably continuously, regarding the distance between the user and the object by means of the signal generated by the indication device, rather than merely warning the user that an object is present. This may enhance the user's lifestyle and experiences in day-to-day situations.

[0009] The indication device is preferably configured to indicate a change of the distance between the user and the object, preferably instantaneously or substantially instantaneously, e.g., within 500 ms, preferably within 400 ms, preferably within 300 ms, preferably within 200 ms, preferably within 100 ms, of an occurrence of the change of the distance between the user and the object. In other words, the indication device may be configured to indicate at least two different distances between the user and the object caused by relative movement between the user and the object such that the user can perceive that the distance between the user and the object is or has changed, e.g., as the user walks towards and / or past and / or around the object. The change of the distance between the user and the object may be indicated to the user by changing one or more properties of the signal.

[0010] To "indicate" or an "indication", within the meaning of the present disclosure, such as indicating the distance to the user by means of the indication device, means a positive indication, e.g., via the signal generated by the indication device. In other words, for instance, a lack of a signal by the indication device is not considered an "indication" or "to indicate" within the meaning of the present disclosure. For instance, indicating a change of the distance between the user and the object means a positive indication as explained above. For instance, indicating a change of the distance by changing one or more properties of the signal generated by the indication device may be one way of (positively) indicating a change of the distance to positively inform the user that the distance has changed. Hence, generating a signal by the indication device for a first distance and not generating a signal for a second distance, e.g., which is greater than the first distance, is not considered to be an indication of a change of the distance within the meaning of the present disclosure.

[0011] Preferably, the indication device is arranged adjacent to the detection device. The indication device and the detection device may be communicatively connected or connectable, e.g., via one or more wires or wirelessly. Preferably, the indication device is arranged on a first side of the support device which faces towards the user's head and the detection device is preferably arranged on a second side of the support device which faces away from the user's head, when the assistance device is worn by the user, the first side and the second side preferably being opposite from each other. The indication device may be in contact with the user's head, when the assistance device is worn by the user.

[0012] The "object", within the meaning of the present disclosure, can be any physical object, such as a human, an animal, a plant, or any other solid and / or liquid matter. The "object" can also be any physical feature, such as a hole, a recess, a protrusion, one or more stairs, etc. The object(s) may include one or more stairs and the assistance device may be configured to indicate to the user, by means of the indication device, a presence and / or a position of the one or more stairs, when the user is wearing the assistance device. The term "visually impaired" refers to a user with partial or total inability of visual perception. Although the assistance device described herein is primarily intended to assist a visually impaired, e.g., a blind, user, the assistance device may be employed by any user for assistance, e.g., while walking, for instance in situations in which visual perception or detection may be impaired, e.g., in dark environments and / or when one or more objects may be hidden and / or occluded from the user's vision. In fact, a relatively wide range of applications of the assistance device disclosed herein is feasible. For example, the assistance device may be configured to be worn and employed by a user during sports and / or sports-related or leisure activities. The assistance device may be configured to assist a user who is disoriented, in particular temporarily disoriented, e.g., when a skier becomes disoriented, e.g., due to fog or ski sickness. As a further example, the assistance device may be configured as and / or may be configured to be used with a virtual reality device and / or an augmented virtuality device and / or an augmented reality device, e.g. such that the detection device may be configured to detect at least one real object in the environment surrounding the user, e.g. an object that the user does not see when wearing the virtual reality device and / or an augmented virtuality device (e.g., a wall). The indication device may be configured to generate at least one signal which may be haptically and / or acoustically perceivable by the user to indicate the distance to the user, and / or warn the user when the user gets closer to the real object.

[0013] As stated above, the assistance device is preferably head-worn. For example, the assistance device may be integrated in and / or may include a hat, a cap, a pair of glasses, e.g., a pair of ski goggles, a headband, a strap, a virtual reality headset, and / or any other type of headgear and / or accessory and / or device configured to be worn on the user's head. In particular, the support device may be or may include a hat, a cap, a pair of glasses, e.g., a pair of ski goggles, a headband, a strap, and / or any other type of headgear and / or accessory and / or device configured to be worn on the user's head. Alternatively, the assistance device may be configured to be worn on one or more other parts of the user's body and / or externally from the user's body, e.g., on a backpack.

[0014] The assistance device allows the distance between the user and the object to be determined and to provide any of the features and / or effects described herein based only on the detection device(s) attached to the user's head via the support device. However, the assistance device may include one or more further detection devices attached or attachable to other body parts, e.g., to enhance one or more functions and / or to provide one or more further functions. The further detection devices of the assistance device may be identical or may be different.

[0015] Preferably, the detection device is or includes at least one infrared sensor configured to detect the object. The inventors have found that infrared sensors may be more reliable and / or less prone to sources of interference, such as electronic devices, which may negatively affect the detection of the object, than other or at least some other types of sensors. Moreover, infrared sensors may be configured to be relatively compact which may reduce the space required to accommodate the respective sensor(s). However, alternatively, the detection device may be or include any type of sensor configured to detect the object and generate data based thereon. For instance, the detection device may be or include an ultrasonic sensor, a lidar sensor, etc.

[0016] Preferably, the assistance device is configured to determine the distance based only on the detection device(s) attached to the support device. A plurality of the detection devices may be attached to the support device, wherein one or more, or all, of the plurality of the detection devices may be used to determine the distance. However, as stated above, the assistance device may include one or more further detection devices attached or attachable to other body parts, e.g., to enhance one or more functions and / or to provide one or more further functions of the assistance device.

[0017] Preferably, the assistance device is void of any detection devices arranged on any other part of the user's body. As stated above, the assistance device may include one or more further detection devices attached or attachable to other body parts, e.g., to enhance one or more functions and / or to provide one or more further functions of the assistance device. However, the assistance device described herein may allow the distance between the user and the object to be determined and to provide any of the features and / or effects described herein based on only the detection device(s) attached to the user's head via the support device. Hence, the assistance device may be void of any detection devices arranged on any other part of the user's body, i.e., any detection devices other than the detection device(s) attached to the support device worn on the user's head.

[0018] Preferably, the assistance device is configured to detect the object in a range of at least 270°, preferably at least 300°, preferably at least 330°, preferably 360°, about a longitudinal axis of the user, when the user is wearing the assistance device. In other words, the assistance device may be configured to detect one or more objects in a range of at least 270°, preferably at least 300°, preferably at least 330°, preferably 360° around the user (i.e., the user's vertical axis), preferably around the user's head. This may allow the entire, or at least a relatively large portion, of the user's environment to be monitored for potential objects and to provide feedback on the objects to the user. For instance, this may allow all sides, i.e., front, rear, and lateral sides, of the user to be monitored. For instance, rather than only monitoring a front of the user, this may also provide feedback to the user regarding one / or more objects which may be located behind the user and / or at the lateral sides of the user. This may provide the user with more extensive information or feedback regarding the user's environment, e.g., compared with a device which only monitors some side(s), e.g., only the front, of the user.

[0019] Preferably, the assistance device is configured to, preferably by means of the detection device, distinguish between different objects and / or different persons and provide an indication, preferably by means of the indication device, which indicates to the user a specific person and / or a specific person of the different objects and / or different persons, respectively. For instance, the assistance device may be configured to apply and / or perform at least one facial recognition process, model, or technique in order to detect a particular person. Alternatively, or additionally, the assistance device may be configured to apply one or more machine learning and / or deep learning models and / or techniques to distinguish or detect a particular person or a particular objection of the different objects and / or different persons, respectively.

[0020] Preferably, the assistance device is configured to be provided and / or fed with data, e.g., to a memory and / or the processor of the assistance device, relating to one or more properties of one or more objects and / or one or more persons, in particular one or more predetermined objects and / or one or more predetermined persons, in particular which the user may encounter. This may allow the assistance device to recognize the one or more objects and / or the one or more persons, e.g., one or more family members and / or familiar persons and / or one or more objects of interest, based on the data, in particular when the assistance device, e.g., the detection device, detects the respective person and / or object while the user is wearing the assistance device. The assistance device may be configured to, based on the data, generate at least one reaction or indication perceivable by the user, preferably by means of the indication device, when the respective object and / or person is detected. Preferably, the assistance device is configured to vary the reaction or indication depending on the respective detected object and / or person. For instance, the assistance device may be configured to generate a first reaction or indication when a first person or object is detected and generate a second reaction or indication when a second person or object is detected based on the data, wherein the first reaction or indication is different from the second reaction or indication. For instance, the reaction(s) or indication(s) may be haptic and / or acoustic, e.g., verbal. For instance, the reaction(s) or indication(s) may be one or more indication patterns, e.g., haptic indication patterns, which may be selected and / or individualized, e.g., by the user. For instance, different indication patterns may be triggered or provided, preferably by means of the indication device, for different objects and / or different persons to distinguish between the different objects and / or different persons. This may let the user know when the one or more certain persons, e.g., familiar persons and / or family members, and / or the one or more objects are in the user's vicinity. The data may be stored in and / or retrieved from a database, e.g., a database of the assistance device and / or an external database. Alternatively, or additionally, the data may be processed, e.g., by the processor of the assistance device, by machine learning and / or context processing.

[0021] Preferably, the assistance device includes a plurality of the at least one indication device and is configured to operate at least some of the indication devices dependently from each other and / or in a coordinated manner and / or to map the plurality of indication devices. For instance, the assistance device may be configured to simultaneously and / or sequentially activate the plurality of indication devices to generate at least one signal, respectively, which is haptically and / or acoustically perceivable by the user. For instance, the assistance device may be configured to activate the indication devices according to a predetermined pattern, a predetermined sequence, and / or with one or more predetermined time intervals between activation of two different indication devices of the plurality of indication devices. The assistance device may be configured such that signals generated by the respective indication devices may vary in one or more properties, e.g., in a pattern of the signals, a strength of the signals, a frequency of the signals, etc. Hence, this may allow the assistance device to synchronize the generation of the signal(s) of the plurality of indication devices, preferably simultaneously and / or sequentially, in particular rather than simply actuating each indication device individually and independently from each other. For instance, the assistance device may be configured to generate a pattern of the signals across the plurality of indication devices simultaneously and / or sequentially.

[0022] Preferably, the assistance device includes a plurality of the at least one detection device and / or a plurality of the at least one indication device. Preferably, the plurality of detection devices are arranged on the support device at equal intervals or distances from each other. Alternatively, or additionally, the plurality of indication devices are arranged on the support device at equal intervals or distances from each other. This may facilitate synchronizing the indication devices and / or the detection devices to each other.

[0023] Preferably, the support device includes at least one cavity and / or recess configured to receive, preferably completely and / or releasably receive, the detection device and / or the indication device and / or the processor. This may allow the detection device and / or the indication device and / or the processor to be protected and / or held within the cavity. This may also allow and / or facilitate removal of the detection device and / or the indication device and / or the processor, e.g., to replace and / or service the detection device and / or the indication device and / or the processor. Preferably, the cavity extends annularly or semi-annularly, preferably around at least a portion of the user's head, when the user is wearing the assistance device. This may allow the cavity to be relatively spacious, e.g., to house multiple components.

[0024] Preferably, the support device includes at least one opening. The detection device may be arranged in or on the support device, e.g., within the cavity, such that the detection device detects the object through the opening. In other words, a field of view of the detection device may extend from or through the opening. The opening may be part of a window element, preferably a movable and / or tiltable window element. This may allow a position and / or an orientation of the opening to be adjusted, e.g., by moving or tilting the window element and / or by replacing a first window element by a different second window element, e.g., a second window element which has an opening with one or more different properties, e.g., one or more different dimensions of the opening, than the first window element.

[0025] The support structure and / or the cavity may be covered by a garment. The garment covering the cavity may be transmissive for, e.g., infrared light. Alternatively, the cavity may be covered by a lid configured to allow infrared light to be transmitted therethrough, such as a polymeric lid configured to allow infrared light to be transmitted therethrough.

[0026] A "field of view" of the detection device, within the meaning of the present disclosure, means a spatial area and / or range in which the detection device can detect the object.

[0027] Preferably, the opening is configured, preferably dimensioned and / or shaped and / or orientated, to shape and / or limit and / or orientate a field of view of the detection device. This may allow one or more properties of the field of view of the detection device to be customized and / or adapted by means of the opening. For instance, this may allow a field of view of two detections, preferably mounted adjacent to each other on the support device, of the assistance device to be coordinated and / or matched to each other, e.g., to allow and / or adjust an overlap of the fields of view of the detection devices.

[0028] Preferably, the opening lies in a plane which extends at an angle greater than 0° to a longitudinal axis or longitudinal plane of the user, when the user is wearing the assistance device, the user is standing in an upright position, and in particular when the user is gazing straight.

[0029] Preferably, the support device includes at least one receiving device configured to at least partially receive, and preferably secure, the detection device. Preferably, the receiving device includes at least one groove configured to receive an edge of the detection device or of a support structure on which the detection device is mounted, the edge preferably extending along at least one side, preferably along at least two sides, preferably along at least three sides, of the detection device or the support structure. For instance, the detection device may be mounted on a plate, e.g., a circuit board (as an exemplary support structure), and an edge of the plate extending along at least one side, preferably along at least two sides, preferably along at least three sides of the plate, may be at least partially received or configured to be at least partially received in the groove. This may facilitate mounting and / or removing the detection device to and from the support device, e.g., by simply sliding the detection device, or the support structure, into and / or out of the groove. For instance, the groove may be open or absent on at least one side of the receiving device, preferably at a top side of the receiving device, when the user is wearing the assistance device, to allow the detection device, or the support structure, to be inserted into and / or removed from the groove.

[0030] Preferably, the receiving device is configured to orient the detection device and / or a field of view of the detection device downwards, e.g., towards a ground on which the user is standing or walking, preferably by an angle to a horizontal plane between 5° and 40°, preferably 5° and 30°, preferably 5° and 20°, preferably 5° and 10°, when the user is wearing the assistance device and the user is standing in an upright position, and in particular when the user's head is gazing straight. This may direct a field of view of the detection device downwards, e.g., in direction of a ground on which the user is standing and / or walking. This may increase the ability of the assistance device to detect objects which are arranged on or towards or close to the ground and which may extend from the ground by a relatively short distance, e.g., by 50 cm. This may increase a range and / or more effectively and / or more efficiently utilize a range across which the assistance device can detect objects.

[0031] Preferably, at least a portion of the receiving device is configured to be movable, preferably rotatable about at least one axis, to change an orientation and / or an alignment and / or a position of the detection device, e.g., to change an orientation and / or an alignment and / or a position of a field of view of the detection device.

[0032] The receiving device may be manually movable and / or may include at least one drive device, e.g., configured to be actuated to move the receiving device. The receiving device may be configured to be moved based on one or more user inputs, e.g., which may be input via an electronic device, e.g., a smartphone, which may be configured to communicate with the assistance device. The drive device may be controllable by the one or more user inputs. Preferably, the assistance device includes a plurality of the at least one processor and / or a plurality of the at least one detection device. At least some of the detection devices may be configured to each communicate individually with a respective processor of the plurality of processors. In other words, at least some of the detection devices may have a dedicated processor. At least some of the processors may be configured to determine the distance independently from each other based on data generated by one of the processors. Alternatively, a single processor may be configured to process the data of all detection devices of the assistance device.

[0033] Preferably, the assistance device includes at least one power source which may be attached to the support device. The power source may be configured to provide power to one or more components of the assistance device, preferably including at least the detection device and / or the processor and / or the indication device. The power source may be or may include at least one battery, preferably at least one rechargeable battery. Alternatively, the assistance device may be powerable by an external power source, e.g., by the battery of an external electronic device, e.g., a smartphone.

[0034] Preferably, the assistance device is configured to detect and indicate to the user, by means of the indication device, a position of the object about a longitudinal axis of the user, when the user is wearing the assistance device. In other words, the assistance device may be configured to detect and indicate to the user, by means of the indication device, different positions, e.g., at least two different positions, of one or more objects about the longitudinal axis of the user. This may increase the user's awareness of the user's environment, e.g., by allowing the user to distinguish objects based on their indicated positions, e.g., by indicating to the user that one or more objects are located at lateral sides of the user but that no object is located in front of the user. This may allow the user to pass through an area within an object or between two or more objects.

[0035] Preferably, the assistance device is configured to detect and indicate, by means of the indication device, the position of the object within a range of no more than 75°, preferably no more than 60°, preferably no more than 45°, preferably no more than 30°, about the longitudinal axis of the user, when the user is wearing the assistance device. In other words, the assistance device may be configured to detect and indicate, by means of the indication device, the position of the object by a degree of accuracy within the above-mentioned range(s). For instance, if the object extends from a 255° position to a 275° position about the longitudinal axis of the user, the signal provided to the user by the assistance device may indicate to the user that the object extends from a 250° position to a 280° position about the longitudinal axis of the user, based on the "no more than 30°" stated above as an example, the same applying to the further ranges cited above. This may provide the user with an indication of a size of the object and / or may increase the user's awareness of the user's environment and / or the accuracy of the indication provided to the user. This may provide the user with greater confidence in navigating past and / or around objects.

[0036] Preferably, the assistance device is configured to indicate to the user, by means of the indication device, a change of the position of the object about a longitudinal axis of the user, when the user is wearing the assistance device. In other words, the assistance device may be configured to detect and indicate to the user, by means of the indication device, different positions, e.g., at least two different positions, of the object about the longitudinal axis of the user. This may help guide the user around and / or past the object.

[0037] Preferably, the assistance device is configured to indicate to the user that the user is passing the object, when the user is wearing the assistance device. This may increase the user's confidence in moving past and / or around objects. For instance, a plurality of the at least one indication device may be provided, e.g., which may be arranged and / or distributed around the user's head, when the assistance device is worn by the user. Two of more of the plurality of indication devices, e.g., at least two adjacent indication devices, may be activated in a pattern, e.g., at least partially sequentially, as the user is passing the object.

[0038] Preferably, the indication device includes at least one vibration device configured to vibrate to indicate the distance, and optionally also one or more properties of the object, preferably including at least a position of the object relative to the user, one or more dimensions of the object, preferably including a height and / or a depth and / or a width of the object, to the user. The vibration(s) generated by the vibration device may provide a relatively intuitive, comfortable, and relatively easily perceivable means of conveying the indication to the user. Thus, the signal may be the vibration(s) generated vibration device. However, alternatively, or additionally, the signal may be generated by other mechanisms and / or means, e.g., the signal may be a pressure applied to the user, in particular to the user's head.

[0039] Preferably, the assistance device includes a plurality of the at least one indication device. The plurality of indication devices are preferably distributed about the user's head, when the assistance device is worn by the user. One or more indication devices of the plurality of indication devices may be communicatively coupled with one or more of the at least one detection device.

[0040] Preferably, the assistance device is configured to alter, during use and preferably depending on the determined distance, at least one property of the signal generated by the indication device. The at least one property may include one or more of the following: a frequency of the signal, an amplitude and / or intensity of the signal, a duration of the signal, a pattern and / or a sequence of the signal, and a perception by the user.

[0041] For example, a location of the acoustic and / or haptic signal around the head may indicate the position of the object.

[0042] Alternatively, or additionally, the frequency of the signal may indicate the height of the object. Alternatively, or additionally, the intensity of the signal may indicate the proximity of the object. For example, an object in front of the user at a distance of 2 m and having a height of 1 m may be indicated by a haptic and / or acoustic signal applied to the center of the user's forehead with a first predetermined frequency (e.g., 2 Hz) and a first predetermined intensity (e.g., X N for a haptic signal). It goes without saying that this is only an example and other signal characteristics could be used, as indicated above.

[0043] Predetermined frequencies and / or intensities for multiple object heights and / or distances, respectively, may be stored in one or more memories of the assistance device. The user may be trained and / or accustomed to the predetermined values and thus able to deduce from, e.g., the frequency and / or intensity output by the assistance device the object's height and / or distance.

[0044] Alternatively, or additionally, specific patterns may be employed to alert the user of particular objects. For example, the assistance device may employ a first predetermined signal pattern to advert the user of stairs going upward, and / or a second predetermined signal pattern to advert the user of stairs going downward, and / or a third predetermined signal pattern to advert the user of a wall, and / or a fourth predetermined signal pattern to advert the user of a hole in the ground. The respective pattern may be applied, e.g., at a location around the user's head that is indicative of where the particular object is to be expected.

[0045] Preferably, the assistance device is configured to simultaneously detect at least two of the at least one object, when the two objects are arranged on a first and a second side of the user which are preferably substantially opposite of each other.

[0046] Preferably, the assistance device is configured to indicate to the user that a third side and a fourth side are free of any objects. Preferably, the third side and a fourth side are substantially opposite from each other. Preferably, the assistance device is configured to detect one or more of the at least one object behind the user, in front of the user, at a first lateral side of the user, and at a second lateral side of the user, and optionally above the user.

[0047] Preferably, the assistance device includes a plurality of the at least one detection device. At least one first detection device of the detection devices may be configured to detect the object behind the user. At least one second detection device of the detection devices may be configured to detect the object in front of the user.
