## Background
TECHNICAL FIELD
Embodiments described herein generally relate to systems and methods for assisting blind or visually impaired persons and, more specifically, to systems and methods for providing environmental feedback to a blind or visually impaired user in response to receiving gestural input.
BACKGROUND
Blind or visually impaired persons have difficulty navigating within their environment because of their inability to detect the location and type of objects within the environment. Blind or visually impaired persons often use a cane to assist them in navigating a space. However, the cane and other traditional navigation methods and mechanisms do not provide detailed information regarding the environment surrounding user upon request by the user.
Accordingly, a need exists for vision-assist devices for blind or visually impaired persons that provide information regarding the environment surrounding the user upon request by the user.
SUMMARY
In one embodiment, system for providing environmental feedback includes one or more processors and a tactile input hardware. The tactile input hardware is communicatively coupled to the one or more processors. The system further includes one or more memory modules communicatively coupled to the one or more processors, one or more sensing devices communicatively coupled to the one or more processors, and machine readable instructions stored in the one or more memory modules that, when executed by the one or more processors, causes the one or more processors to receive environmental information from the one or more sensing devices, receive a gestural input on the tactile input hardware, and generate feedback regarding a subset of the environmental information acquired by the one or more sensing devices in response to the gestural input received on the tactile input hardware.
In another embodiment, a system for providing environmental feedback includes a mobile device having tactile input hardware and an auxiliary sensing apparatus including one or more sensing devices. The mobile device is configured to receive a gestural input on the tactile input hardware of the mobile device. The gestural input includes a gestural pathway along a surface of the tactile input hardware. The gestural pathway corresponds with a clock face direction. The wearable auxiliary sensing apparatus is configured to receive environmental information regarding one or more points of interest within an environment disposed in the clock face direction of the gestural pathway. At least one of the wearable auxiliary sensing apparatus and the mobile device are configured to provide feedback regarding the one or more points of interest within the environment disposed in the clock face direction of the gestural pathway in response to the gestural input received on the tactile input hardware of the mobile device.

Referring now to FIGS. 1 and 2, a non-limiting, example auxiliary sensing apparatus 140 that is wearable by the user 170 is schematically depicted. In some embodiments, the auxiliary sensing apparatus 140 has a necklace configuration intended to be worn around the neck of the user 170 and may include portions extending downward from the neck and along the chest and/or the back of the user 170. Further, the auxiliary sensing apparatus 140 may include one or more sensing devices, such as proximity sensors 122 and cameras 118, configured to acquire environmental information regarding the environment 300 as well as points of interest 310 positioned in the environment 300.

Referring now to FIG. 2, the environmental feedback system 100 is schematically depicted within an environment 300. The environment 300 may be an indoor environment or an outdoor environment and may include one or more points of interest 310 representative of one or more locations or features present in the environment 300. In some embodiments, the environment 300 may be an indoor facility, for example, a mall, or the like, and the points of interest 310 may be various locations within the indoor facility. In the non-limiting example depicted in FIG. 2, the points of interest 310 represent a bank, an information desk, a coffee shop, a set of stairs, and an elevator bank. It should be understood that FIG. 2 depicts one example environment 300 and the points of interest 310 referenced herein may be any location, structure, and the like positioned within the environment 300. Additionally, in some embodiments, the environment 300 may comprise an outdoor environment and the one or more points of interest 310 may comprise outdoor structures, such as buildings, roads, or the like, and outdoor environmental features, such as hills, rivers, or the like.
Referring again to FIGS. 1 and 2, a method of providing feedback pertaining to one or more points of interest 310 of the environment 300 is contemplated. The method of providing feedback pertaining to the points of interest 310 may be implemented as logic within the machine readable instructions that, when executed by the one or more processors 102, provides feedback in response to gestural input received by the mobile device 200. It is noted that, while the method is described as following a specific sequence, additional embodiments of the present disclosure are not limited to any particular sequence. For example, while the embodiments described herein follow a sequence of acquiring environmental information regarding the points of interest 310 before receiving gestural input, in some embodiments, the environmental feedback system 100 acquires environmental information regarding the points of interest 310 after receiving gestural input.
Referring still to FIGS. 1 and 2, the environmental feedback system 100 may first determine a location of the user 170, the mobile device 200, and/or the auxiliary sensing apparatus 140. In operation, the location sensors 124 may receive a satellite signal from one or more global positioning satellites, for example, with a conductive element. Next, the one or more processors 102 execute machine readable instructions to transform the satellite signals received by the location sensors 124 into a data signal indicative of a location of the environmental feedback system 100 (e.g., the current location at the time the satellite signal is received). Further, alternative methods of determining the location of the user 170, the mobile device 200, and/or the auxiliary sensing apparatus 140 are contemplated, for example, based on an output from the proximity sensor 122 and/or the camera 118 pertaining to the distance between the mobile device 200 and/or the auxiliary sensing apparatus 140 and one or more points of interest 310. Additionally, the location of the points of interest 310 may be stored in the one or more memory modules 106 and/or the environmental feedback system 100 may be able to access these locations, for example, through communication with one or more outside networks, servers, or the like.
The environmental feedback system 100 may next acquire environmental information regarding all or a subset of the surrounding environment, for example, one or more points of interest 310. The environmental feedback system 100 may acquire this environmental information using one or more sensing devices of the auxiliary sensing apparatus 140 and/or the mobile device 200, for example, cameras 118, proximity sensors 122, or the like. In some embodiments, the environmental feedback system 100 may acquire environmental information in response to gestural input received by the mobile device 200, as described below (FIGS. 3-6). In some embodiments, the environmental feedback system 100 may continuously acquire information regarding the points of interest 310 located proximate the user 170. In other embodiments, the environmental feedback system 100 may access environmental information by communicating with one or more outside networks, servers, or the like. In each of these embodiments, the environmental feedback system 100 may store this acquired information, for example, within the memory modules 106 and may access this stored environmental information upon receipt of gestural input by the user 170.
Further, the environmental feedback system 100 may acquire environmental information regarding points of interest 310 located in a particular clock face direction from the user 170, the mobile device 200, and/or the auxiliary sensing apparatus 140. The clock face direction may be a relative direction of the points of interest 310 described using the analogy of a 12-hour clock lying flat in front of and/or below the user 170. A schematic clock 320 showing the clock face positions of a 12-hour clock is depicted in FIGS. 2-6 to provide reference coordinates. As depicted by the schematic clock 320, the 12-o'clock direction is directly ahead of the user 170, the 3-o'clock direction is to the right of the user 170, the 6-o'clock direction is directly behind the user 170, and the 9-o'clock direction is to the left of the user 170. It should be understood that each clock face direction (1-12) may be representative of that particular clock face direction with respect to the user 170, the mobile device 200, and/or the auxiliary sensing apparatus 140. Further, each clock face direction may correspond to a clock face position on the display 108 of the mobile device 200 corresponding to the radial positions of the schematic clock 320. Further, it should be understood that the clock face directions and clock face positions are described and referenced herein for ease of understanding and the environmental feedback system 100 may acquire and provide information corresponding to any direction from the user 170, not just discrete clock face directions.
Referring now to FIGS. 3-6, the environmental feedback system 100 may next receive a gestural input on the display 108 of the mobile device 200, having tactile input hardware, such as a touchscreen. The gestural input may comprise gestural pathways 210 corresponding to a request for information regarding a subset of the environment 300, for example, the one or more points of interest 310 positioned in the environment 300. In some embodiments, the gestural pathways 210 depicted in FIGS. 3-6 each represent a path of tactile input receivable by the mobile device 200, for example, tactile input between the user 170 and the display 108. In alternative embodiments, the gestural input may comprise non-contact input, for example, a gesture along one or more gestural pathways 210 within a threshold distance from the display 108. The threshold distance may comprise any distance, for example, 1 cm, 3 cm, 5 cm, 10 cm, or the like. In these embodiments, the non-contact gestural input may be detected by one or more sensing devices of the mobile devices 200, for example, cameras 118, proximity sensors 112, or the like,
Referring now to FIG. 3, a plurality of gestural pathways 210 comprising one or more rays 220 positioned on the display 108 of the mobile device 200 are schematically depicted. In this embodiment, each ray 220 starts in a central location 222 on the display 108 and extends radially from the central location 222 such that each ray 220 extends along a clock-face direction on the display 108. Each ray 220 may comprise a vector pointing towards a location in the environment 300 surrounding the user 170, for example, one or more points of interest 310. In some embodiments, when the environmental feedback system 100 receives a gestural input along an individual ray 220 (e.g., a swipe), the gestural input comprises a request for feedback regarding the points of interest 310 positioned in the vector direction of the received ray 220. In some embodiments, received gestural input along the ray 220 may cause the environmental feedback system 100 to acquire information regarding the points of interest 310 located in the vector direction of the ray 220, and provide feedback including the acquired information. In other embodiments, the received gestural input may prompt the environmental feedback system 100 to access stored information regarding the points of interest 310 located in the vector direction of the ray 220, and provide feedback including this stored information. As a non-limiting example, in the environment 300 depicted in FIG. 2, a gestural input along the ray 220 in the 12 o'clock direction on the display 108 of the mobile device 200 comprises a request for feedback regarding the bank positioned in the 12 o'clock direction.
Referring now to FIG. 4, another plurality of gestural pathways 210 is schematically depicted on the display 108 of the mobile device 200. The illustrated plurality of gestural pathways 210 comprises one or more sweeping pathways 230 extending along an arc between a starting point 232 and a termination point 234. In some embodiments, the sweeping pathways 230 may traverse a plurality of clock face positions corresponding to a plurality of clock face directions. An individual sweeping pathway 230 may extend along an arc between a starting clock face position and a terminating clock face position, for example, between a starting clock face position comprising the 9-o'clock position and a terminating clock face position comprising the 3-o'clock position. In some embodiments, the sweeping pathway 230 may be a request for information regarding points of interest 310 in each clock face direction corresponding to each clock face position between and including the starting point 232 and the termination point 234 and may be a request for information regarding all points of interest 310 between and including the starting point 232 and the termination point 234. It should be understood that the sweeping pathway 230 may comprise an arc along any circumferential length of the display 108, for example from any first clock face position to any second clock face position. Additionally, it should be understood that the sweeping pathway 230 may extend in the clockwise direction or in the counterclockwise direction. As a non-limiting example, in the environment 300 depicted in FIG. 2, a gestural input along the sweeping pathway 230 from the 9 o'clock position to the 3 o'clock position in a clockwise direction on the display 108 of the mobile device 200 comprises a request for feedback regarding the elevator positioned in the 9-o'clock direction, the bank positioned in the 12 o'clock direction, the concierge positioned in the 1 o'clock direction, and the coffee shop positioned in the 3 o'clock direction.
Referring still to FIG. 4, in some embodiments, the sweeping pathway 230 may be a request for information regarding points of interest 310 in a vector direction of the sweeping pathway 230 at the termination point 234 of the sweeping pathway 230. For example, a sweeping pathway 230 extending in the clockwise direction along an arc terminating at the 12-o'clock position may comprise a request for information regarding points of interest 310 substantially to the right of the mobile device 200 (and/or the user 170) and a sweeping pathway 230 extending in the clockwise direction along an arc terminating at the 6-o'clock position may comprise a request for information regarding points of interest 310 substantially to the left of the mobile device 200 (and/or the user 170). It should be understood that in this embodiment, the sweeping pathway 230 may be used to request information regarding points of interest 310 positioned in any direction. As a non-limiting example, in the environment 300 depicted in FIG. 2, a gestural input along the sweeping pathway 230 from the 9 o'clock position to the 3 o'clock position in a clockwise direction on the display 108 of the mobile device 200 comprises a request for feedback regarding the stairs positioned in the 6-o'clock direction.
Referring now to FIG. 5, another plurality of gestural pathways 210 is schematically depicted on the display 108 of the mobile device 200. In this embodiment, the plurality of gestural pathways 210 comprises one or more iterative arcs 240 extending circumferentially along the display 108 between a plurality of clock face directions. The iterative arcs 240 comprise a starting point 242 corresponding with a starting clock face position, a termination point 244 corresponding with a terminating clock face position, and one or more intermediate points 246 corresponding with one or more intermediate clock face positions on the display 108. The intermediate points 246 are positioned between the starting point 242 and the termination point 244 and may correspond to locations along the iterative arc 240 where the motion of the gestural input pauses, for example, for 0.5 sec, 1 sec, 2 sec, or the like. In operation, the environmental feedback system 100 may acquire and provide information regarding each points of interest 310 along clock face directions corresponding to the starting point 242, the termination point 244, and each intermediate point 246. For example, an individual iterative arc 240 may comprise a starting point 242 corresponding to the 9-o'clock direction, an intermediate point 246 corresponding to the 12 o-clock direction, and a termination point 244 corresponding to the 3-o-clock direction. In this embodiment, the environmental feedback system 100 may acquire information regarding points of interests 310 located in each of those clock face directions (3 o'clock, 12 o'clock, and 9 o'clock) and provide feedback including information regarding those points of interest 310 (for example, as depicted in the environment 300 in FIG. 2, information regarding the elevator, the bank, and the coffee shop). Additionally, it should be understood that the iterative arc 240 may extend in the clockwise direction or in the counterclockwise direction.
Referring now to FIG. 6, another plurality of gestural pathways 210 are schematically depicted on the display 108 of the mobile device 200. In this embodiment, the plurality of gestural pathways 210 comprise one or more tapping locations 250. The tapping locations 250 may correspond to clock face positions on the display 108. In this embodiment, the gestural input comprises taps at the tapping locations 250. The taps may comprise a single tap or a plurality of taps, for example, a double tap. Gestural input comprising a tap at an individual clock face position may be a request for information regarding points of interest 310 positioned in the clock face direction corresponding with the clock face position of the tap.
Referring again to FIGS. 3-6, the environmental feedback system 100 may be configured such that multiple gestural inputs are receivable along an individual gestural pathway 210 and may correspond to various requests for environmental information. In some embodiments, a first gestural input may comprise a request for information regarding points of interest 310 located in the clock face direction corresponding with the first gestural input and a second, follow up gestural input may comprise an additional request for information regarding the points of interest 310. The follow up gestural input may correspond with a request for a particular type of information, such as navigational information or descriptive information. For example, a first gestural input along a ray 220 may correspond with a request for information, such as descriptive information, regarding a point of interest 310 in the clock face direction of the ray 220 and a second, follow up gestural input along the ray 220 may correspond with a request for different information with respect to the point of interest 310, such as navigational information. Additionally, the first gestural input may be a request for a first level of informational detail, for example, the presence of the point of interest 310 and the second, follow up gestural input may be a request for a second level of informational detail, for example, hours of operation, items for sale, or the like. The follow-up gestural inputs may be any number of gestural inputs, for example, three, four, or more gestural inputs. Further, it should be understood that multiple gestural inputs may be received along any of the gestural pathways 210 described herein, such as additional taps at tapping locations 250, additional swipes along sweeping pathways 230, or the like.
Referring again to FIGS. 3-6, the environmental feedback system 100 may be configured such that a combination of gestural inputs are receivable along different gestural pathways 210 and these gestural inputs may correspond to various requests for environmental information. For example, in one non-limiting example, a first gestural input may comprise a ray 220 along a particular clock face direction followed by a second gestural input of a tap at a tapping location 250 substantially co-located with the end of the ray 220. In this embodiment, the ray 220 may be a request for a first level of detail and the tap may be a follow-up request for a second level of detail. Also, in this embodiment, the gestural input along the ray 220 may be a request for one type of information, such as descriptive information, and the gestural input at the tapping location 250 may be a request for a second type of information, such as navigation information. It should be understood that the environmental feedback system 100 may be configured to receive any combination of gestural inputs along gestural pathways 210. Further, it should be understood that the gestural inputs described above are merely a non-exhaustive list of gestural inputs and gestural pathways 210. Any exemplary gestural input received along any exemplary gestural pathway 210 is contemplated, for example, multi-directional inputs, such as scrubbing, or the like, and multi-finger inputs, such as pinching, or the like.
As stated above, the environmental feedback system 100 provides feedback regarding the one or more points of interest 310 in response to the received gestural input, for example, audible, tactile, visual, and/or haptic feedback regarding one or more points of interest 310. In response to the received gestural input, the environmental feedback system 100 may provide audible feedback using the one or more auditory devices 120 of the mobile device 200 and/or the auxiliary sensing apparatus 140. The audible feedback corresponds with the received gestural input and may comprise particular information about the point of interest, for example, descriptive and/or navigational information regarding the point of interest 310. The content of the audible feedback may correspond with the request received via gestural input on the display 108 of the mobile device 200. Further, it should be understood that the content of the feedback may be dependent on the mode of the environmental feedback system 100, as described below.
As a non-limiting example, in the environment 300 depicted in FIG. 2, a gestural input along the ray 220 (FIG. 3) in the 12 o'clock direction on the display 108 of the mobile device 200 may cause the environmental feedback system 100 to provide environmental feedback regarding the bank positioned in the 12 o'clock direction, for example, vocal feedback stating, for example, “there is a bank directly in front of you,” “there is a bank in the 12 o'clock direction,” or “the bank directly in front of you is a CHASETM bank and is open from 9:00 AM to 5:00 PM.” Additionally, in some embodiments, the environmental feedback system 100 may provide tactile and/or haptic feedback regarding the environment 300, for example, using one or more tactile feedback devices 126 embedded within and/or positioned on the auxiliary sensing apparatus 140 and/or the mobile device 200. The tactile and/or haptic feedback may comprise vibrations, pressure, puffs of air, or the like. The tactile feedback may be indicative of navigational and/or descriptive information regarding the point of interest 310. Further, in alternative embodiments, for example, embodiments configured for a non-visually impaired user 170, the feedback may include visual information regarding the environment 300 presented on the display 108 of the mobile device 200.
In some embodiments, the environmental feedback system 100 may be implemented by a computer program product such as a mobile device application. For example, the mobile device application may be selectable by the user 170 on the display 108 of the mobile device 200. By selecting the mobile device application, the display 108 of the mobile device 200 displays an interface which provides a location for gestural input receivable by the mobile device 200, for example, tactile input along one or more gestural pathways 210.
Further, in some embodiments, the environmental feedback system 100 may be placed in one or more modes, for example, using the mobile device application. The modes may include a navigation mode, a descriptive mode, or the like. When the environmental feedback system 100 is placed in the navigation mode, the information provided by the environmental feedback system 100 comprises navigational information with respect to the one or more points of interest 310, for example, the location of the point of interest and/or directions to the one or more points of interest 310, e.g., step-by-step directions, or the like. When the environmental feedback system 100 is placed in the descriptive mode, the environmental information provided by the environmental feedback system 100 comprises descriptive information, such as, for example, the presence of the points of interest 310, and additional detail regarding the points of interest 310, for example, the hours of operation of the points of interest 310, items and services offered at the points of interest 310, or the like.
It should be understood that embodiments described herein provide for systems and methods for providing feedback to a user, for example, a blind user, regarding one or more points of interests located in an environment surrounding the user based on a received tactile input. The systems and methods allow the user to request information regarding points of interest positioned in a particular clock face direction with respect to the components of the environmental feedback system and/or the user by inputting gestural input into tactile input hardware of a mobile device. Further, the systems and methods allow the user to request varying levels of detail regarding the points of interest positioned in the surrounding environment by inputting particular types and combinations of gestural input. Further, the systems and methods provide feedback to the user regarding the points of interest in the surrounding environment based on the received gestural input.
