Systems and methods for camera-based fingertip tracking are disclosed. One such method includes identifying at least one location of a fingertip in at least one of the video frames, and mapping the location to a user input based on the location of the fingertip relative to a virtual user input device.

A clip bearing Braille indicia removably attachable to fabric comprises a body member having a face bearing Braille indicia and a clipping member configured to removably clip the body member to the fabric with the Braille indicia facing outwardly. A button bearing Braille indicia for attachment to fabric includes a body having a face bearing Braille indicia and attachment means for facilitating attachment of the body of the button to the fabric with the Braille indicia facing outwardly. A bead bearing Braille indicia for attachment to an article using thread comprises a body having a face bearing Braille indicia and a passage, through the body beneath the face, for receiving the thread.

The simple gesture control of the user interface can be used by visually impaired or blind people in order to enter telephone numbers or account numbers for example. The user interface and the method constitute a shift from the current paradigm of guiding a user on touchscreens, which has precisely the advantage of the handeye coordination allowed by the touchscreen, wherein a user touches the exact location on the touchscreen where a corresponding selection surface is visualized. Instead, a swiping gesture is supported which can be carried out in any region on the touch-sensitive surface and shifts the focus from one selection surface or virtual button to the next. The swiping gesture can be carried out not just in the horizontal and vertical direction but also in a diagonal direction. Diagonal swiping gestures allow a particularly quick selection of the corresponding virtual buttons.

Providing haptic communications includes attaching to skin of a user a haptic device that produces touch impulses, electronically transmitting a message to the haptic device, converting the message to touch impulses, and providing the touch impulses to the user. Messages may be converted to touch impulses using coding from the Braille system or Morse code. Messages may be converted to touch impulses using Braille coding where the touch impulses are provided by a positional matrix that is part of the device. Messages may be converted to touch impulses using Morse coding where a Morse code dot is provided by a brief touch and where a Morse code dash is provided by a longer touch. The haptic device may be a patch or a sticker attached to the user with a biocompatible adhesive. The haptic device may notify the user of receipt of a new message using special touch symbols.

A writing instrument that has a tip for directly contacting and writing on a medium and a body contiguous with the tip, the body configured for grasping the writing instrument for writing on the medium. The writing instrument further has a first recess on a first side of the writing instrument, the first recess comprising a first braille color indicator comprising a first plurality of raised dots.

Techniques for performing Braille mirroring are disclosed. In one aspect, content is converted into Braille content, and then formatted for each of a plurality of Braille displays. The formatted content is then sent to each of the Braille displays. In another aspect, data identifying a primary Braille display in a plurality of Braille displays is stored. Input requesting that a data processing apparatus perform an action is received from one of the Braille displays, and it is determined whether to perform the action, based in part on whether the requesting Braille display is the primary Braille display.

Device especially for a display for visually impaired people and display including such a device. The device includes a tactile screen, especially for a display for visually impaired people, said screen including, on one of the edges thereof, a line of icons that each correspond to a piece of software. The surface of the said tactile screen is divided at least into as many columns as icons, and the device includes an element for determining the position of the finger of a user on said tactile screen in order to control the implementation of the software corresponding to the determined position of the user's finger.

Disclosed are systems, computer-readable mediums, and methods for receiving, from a sensor array, three-dimensional sensory data associated with an environment of a person. The three-dimensional sensory data is converted into a two-dimensional representation. An obstacle is located within the environment based upon the sensory data. The obstacle is mapped onto the two-dimensional representation and the two-dimensional representation is mapped onto a plurality of actuators within a vibrotactile interface. One or more of a plurality of actuators are controlled based upon the mapping of the two-dimensional representation onto the plurality of actuators to provide tactile input to the person that represents a location of the obstacle.

The present invention includes a novel and modern numbering system design modernizing the design of gaming pieces, such as dice and dominos, while maintaining the qualities of utility for which these pieces were built. The novel design adds not only a pleasing and improved visual quality, but also a tactile quality that enhances the handling of the gaming piece.

A braille display comprising an outer wall comprising an outer surface, an inner surface and a plurality of holes extending between the outer surface and the inner surface and which are arranged in an at least substantially regular pattern relative to each other. The braille display is further provided with braille cells wherein each braille cell comprises at least one tactile member which is movable between a first outer position and second outer position and activations means for moving the at least one tactile member between the first and second outer position. The at least one tactile member comprises a free top and each braille cell is located near the inner surface of the tactile member wherein each tactile member extends through one of the holes from the inner surface in a direction of the outer surface, at least if the tactile member is in the second position and wherein a position of the free top of the tactile member relative to the outer surface when the tactile member is in its first position differs from the position of the free top of the tactical member relative to the outer surface when the tactile member is in its second position, wherein each braille cell of a group of the braille cells is attached to the outer wall by means of a connection which acts on the one hand on the braille cell and on the other hand on the outer wall at a location adjacent to the braille cell.
