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

An intersection blind-guiding system includes: a blind-guiding terminal, a plurality of blind road sensors, and a processor configured to be coupled to the blind road sensors. The blind-guiding terminal includes a blind-guiding terminal sensor configured to transmit a sensing signal. The blind road sensors include at least one first blind road sensor and at least one second blind road sensor. The blind road sensors are configured to separately receive the sensing signal transmitted by the blind-guiding terminal sensor, and upload corresponding sensing information. The processor is configured to receive the sensing information uploaded by the blind road sensors, locate a current position of a blind person carrying the blind-guiding terminal, determine a direction in which the blind person previously traveled, determine geographic distribution information of the current position of the blind person, and send a command carrying the geographical distribution information.

A navigation system for a blind individual to guide the individual through a virtual environment, includes a transponder adapted to be carried by the individual, a tracking system for determining the position of said transponder within the virtual environment, and a feedback system coupled to said transponder to generate a non-visual sensory signal indicative of said position of said transponder. The transponder has a primary sensor direction that is aimed by the individual, and the non-visual sensory signal provides indications of virtual objects aligned with said primary sensor direction, whereby the individual may be guided to find or avoid virtual objects in said virtual environment.

A smart locker system with assistance for a visually impaired user is disclosed. Each locker in the smart locker system includes a beacon that emits a signal either before the locker door is released or at the same time as the locker door is released. The beacon is used by a visually impaired user to locate the specified locker before it opens or at the same time as it opens. The beacon may be a haptic device that causes the specified locker to vibrate, which allows the user to find the locker by feel. The beacon may also be an auditory device that causes the specified locker to emit a sound, which allows the user to find the locker by sound.

In some embodiments, a haptic device comprises first and second multi-dimensional spatial haptic devices. The first spatial haptic device includes a handle to represent a location of one object in a virtual document or space. The second spatial haptic device includes a handle to represent a location of another object in the same virtual document or space. The first and the second handles are spatially registered with respect to each other. In some embodiments, a third spatial haptic device includes a handle to represent a location of yet another object in a virtual document or space.

A method for navigational assistance for the visually impaired can include determining that an image captured by an imaging device contains an unknown object and determining that the unknown object is not resolvable within a threshold period of time. The method can further include performing an operation to reallocate computing resources between memory devices couplable to the imagining device in response to determining that the unknown object is not resolvable within the threshold period of time. Data corresponding to the unknown object can be written to the reallocated computing resources and an operation involving the data corresponding to the unknown object can be performed to resolve the unknown object using the reallocated computing resources.

Provided is an information output apparatus including one or more information output units, wherein each information output unit includes a coil arranged to be connected to a power source, such that a current flows in the coil; a base unit configured to accommodate the coil; and a driving indicator, which is arranged in the base unit to be apart from and close to the coil to be driven by a current flowing in the coil and is configured to move in a first direction toward the coil and a direction opposite thereto to rotate while being connected to the base unit and to move in a second direction crossing the first direction to be recognized by a user.

A method of teaching keyboard instruments involves placing semi-permanent plates on specific keys of the keyboard, providing tactile stimulation which will develop muscle memory and confidence in playing correct notes. Different textures and colors may be employed to help differentiate plates and associated keys from others. Placement of plates on keys is to be determined by the instructor in consideration of the student's needs. Placement may be made on one or multiple keys, which may include an entire middle octave. Texturing may be a subtle as Braille characters or more bold designs and individual shapes of the plates may be flat or may be shaped to facilitate hand posture. Colors may be associated with specific notes on the grand staff to provide a visual aid. Finger adornments may also be used to aid in color correspondence. Plates may be held onto piano keys by utilizing either wet or dry adhesives.

A tactile indicator 200 for use in an aerosol provision system 300. The tactile indicator 200 may be supplied with a given aerosol provision system 1, or may be retrospectively used with, or attached to, an aerosol provision device 2. The tactile indicator 200 may be electrically operated, or may be mechanically operated and/or configured to remain stationary in use. The tactile indicator 200 may therefore facilitate the operation of an aerosol provision system 1, particularly to those users which have a visual impairment.

A tactile display for dynamically reproducing content from an electronic device, such as a computer, tablet, mobile phone or other device, in a touch-sensory format, such as Braille. The tactile display includes a housing and a plurality of tactile elements. The tactile elements are movable relative to the housing between an extended position for engagement by a user and a retracted position at or inward of a surface of the housing.
