A computer-implemented method for dynamically calibrating a virtual Braille keyboard implemented on a touch screen is provided. The virtual Braille keyboard includes a plurality of virtual keys each associated with a corresponding finger of a user and with a variable key location on the touch screen. The method includes detecting typing events, each involving one or more of the fingers of the user contacting the touch screen at corresponding touch locations and defining one or more active fingers for the typing event. The method also includes updating, in real-time, the variable key location of the virtual key associated with each active finger in view of the corresponding touch location detected during a current one of the typing events. A computer-implemented method for reinitializing a calibration of a virtual Braille keyboard for a single one of the two hands of a user is also provided.

The adaptation of a regular pocket size computer for use by a visually impaired person is provided. A framework is firstly provided for building adapted applications, having adapted input and output services, a system resources library including tools for interacting with these adapted services and an adaptation library. A tactile keyboard is further provided to allow data entry through the screen interface of the computer. The tactile keyboard includes a membrane having raised keys on one side and corresponding screen activating tips on the other. Means for mounting the keyboard above the computer with the screen activating tips positioned in contact less alignment with the corresponding selected areas of the screen interface are also provided.
