The present invention discloses an indoor Electronic Traveling Aid (ETA) system for blind and visually impaired (BVI) people. The system comprises a headband, intuitive tactile display with myographic (EMG) feedback, controller, and server-based methods corresponding to three operation modalities. In 1.sup.st modality, sighted users mark routes, map navigational directions, and create semantic comments for BVIs. This information of routes is continuously collected and estimated in ETA servers. In the 2.sup.nd modality, BVIs choose the routes from servers, thereby, are supplied with real-time navigational guidance. Also, an EMG interface is used, where the user's facial muscles are enabled is to send commands to the ETA system. In the 3.sup.rd modality, BVIs receive real-time audio guidance in complex or unforeseen situations: ETA provides a crowd-assisted interface and real-time sensory (e.g., video) data, where crowd-assistants analyze the situation and help the BVI to navigate.

Provided is an information processing device capable of operating in accessibility mode of guaranteeing browsing corresponding to disability or functional degeneration of a body of an operator. A source device checks whether each sink device is in accessibility mode at the time of connection, and determines whether or not metadata for supporting disability (for example, audios, videos, texts, vibration information, or the like) is added to the sink device in the accessibility mode at the time of transmission of original image/audio data. The source device changes a metadata transmission method in accordance with whether the accessibility mode of each sink device is turned on or off.

A method of augmenting sight in an individual. The method comprises obtaining an image of a scene using a camera carried by the individual; transmitting the obtained image to a processor carried by the individual; selecting an image modification to be applied to the image by the processor; operating upon the image to create a modified image using either analog or digital imaging techniques, and displaying the modified image on a display device worn by the individual. The invention also relates to an apparatus augmenting sight in an individual. The apparatus comprises a camera, carried by the individual, for obtaining an image of a scene viewed by the individual; a display carried by the individual; an image modification input device carried by the individual; and a processor, carried by the individual. The processor modifies the image and displays the modified image on the display carried by the individual.

Systems and methods for disability simulations and accessibility evaluations of content is disclosed. A disclosed system runs using an information loss determination engine via a processor, for a given disability, at least one simulation to simulate how a content is experienced by a user having such disability. The system computes information loss based on comparison of the simulated content with desired original content. Further, the system transmits data packets indicative of a content optimization strategy that is determined based on the determined information loss.

A method includes receiving information about a color blindness of a viewer and an electronic display; receiving information about an input image including input R, G, and B values for pixels composing the input image; transforming each pixel's input values to corresponding x and y values in a CIE color space; identifying which of the pixels are within a filter area in the CIE color space; adjusting a color of the pixels that are within the filter area away from a confusion line for the color blind person to provide a corresponding color-modified pixel; generating a color-modified image composed of the color-modified and original pixels; and displaying the color-modified image with the electronic display.

Described are various embodiments of a digital display device to render an image for viewing by a viewer having reduced visual acuity, the device comprising: a digital display medium for rendering the image based on pixel data related thereto; a complementary light field display portion; and a hardware processor operable on said pixel data for a selected portion of the image to be rendered via said complementary light field display portion so to produce vision-corrected pixel data corresponding thereto to at least partially address the viewer's reduced visual acuity when viewing said selected portion as rendered in accordance with said vision-corrected pixel data by said complementary light field display portion.

In one aspect, a device includes at least one processor and storage accessible to the at least one processor. The storage includes instructions executable by the at least one processor to receive input from at least one sensor, identify a characteristic of a user based on the input from the at least one sensor, and alter at least one setting of the device based on the identification of the characteristic. The at least one setting is related to presentation of content using the device.

A user interface for a visually impaired user of a mobile computer system. A touch interface is enabled on a touch screen and an audio interface is enabled on a loudspeaker and a microphone. Remotely stored content is previously ordered in a list or tree. The previously ordered remotely stored content is accessible to the visually impaired person by playing the content on the loudspeaker using multiple inputs including a touch gesture on the touch screen and a speech input into the microphone. In accordance with the inputs, an order is changed of navigating the content within a list for a future use of the user interface

According to one embodiment, a method, computer system, and computer program product for dynamic braille actuation is provided. The embodiment may include receiving a plurality of media. The embodiment may also include translating one or more visual elements of the received plurality of media to braille. The embodiment may further include generating a plurality of protrusions corresponding to the one or more translated visual elements on a surface of a stretchable display screen using microfluidic actuation.

Disclosed in the present invention is a head-mounted electronic vision aid device and an image magnification method thereof. The head-mounted electronic vision aid device comprising a memory unit, a processing unit, an image zooming unit, and at least one ranging unit; the ranging unit being configured to obtain distance data between a target object of interest to a user and the device and/or three-dimensional profile data of the object and output the data to the processing unit; the memory unit stores a correspondence table between the distance data and the magnification of the image zooming unit; the processing unit confirms the target object of interest to the user, performs operations on the distance data and/or the three-dimensional profile data of the object, and outputs an magnification matching the distance data to the image zooming unit according to the correspondence table; and the image zooming unit can automatically adjust to the matching magnification. For visually impaired users, accurate, intuitive and rapid automatic magnification of the target objects of interest can be realized on demand. Compared with the prior art, the repeated and tedious manual adjustment is avoided, and the user experience is greatly improved.
