There is provided a system including an input device configured to transmit data and a broadcast terminal configured to receive the data from the input device and simultaneously transmit the data over a local network to a plurality of computing devices in connection with the broadcast terminal. The broadcast terminal is further configured to dynamically control the transmission of the data to and the connection to each of the plurality of computing devices. The system further includes at least two computing devices configured to receive the data from the broadcast terminal over the local network and to dynamically manipulate the data to create custom data where the custom data is unique to each of the computing devices.

Visual assistance systems and related methods are disclosed. A visual assistance system includes a visual assistance service configured to receive and display images from a user device on an electronic display for a live assistant. The visual assistance service is also configured to transmit assistant audio from the live assistant conveying information derived by the live assistant's review of the images. A visual assistance system comprises a user device configured to capture and transmit the images to the visual assistance service. The user device is also configured to receive the assistant audio from the visual assistance service, and reproduce the assistant audio to a user of the user device. The user is registered with the visual assistance service as having at least a minimum level of visual disability. A method of operating the visual assistance system includes receiving the images from, and transmitting the assistant audio to the user device.

Techniques for providing adaptive assistive technology for assisting users with visual impairment can be used on a computing device. These techniques include displaying content to a user, capturing a series of images or video of the user using a camera, analyzing the series of images or video to determine whether the user is exhibiting behavior or characteristics indicative of visual impairment, and rendering a magnification user interface on the display configured to magnify at least a portion of the content of the display based on a determination that the user is exhibiting behavior or characteristics indicative of visual impairment. The magnification user interface may be controlled based on head and/or eye movements of the user of the computing device.

A method and system for outputting a text content of text data to a voice, including using a transmitting terminal of a sender to transmit text data to a receiving terminal via a communications network, converting text content of the text data to speech and outputting the speech in the sender's voice characteristics using a voice database.

A mobile terminal including a display, and a controller coupled to the display, the controller configured to display information on the display, scroll the displayed information in response to a touch and moving input applied on the display in a direction, and refresh the displayed information if the touch and moving input is released subsequent to the scrolling of the displayed information.

A braille learning apparatus includes a plurality of slave blocks for receiving braille from a learner, and a master station configured to: receive braille learning information from an external braille learning information terminal, when slave blocks corresponding to a specific braille inputted by the learner are mounted, determine whether the specific braille inputted to the slave blocks match a learning word, and transmit a determination result to the external braille learning information terminal.
