Abstract: An improved user interface for use with a mobile telecommunication device such as a mobile phone to make its featured more accessible to a sight-impaired user. The user interface employs a collection of distinguishable non-visual (NV) cues that are selectively generated as the user chooses a feature for activation by navigating through a menu system. The NV cues may take any of several forms, but are most usually vibration pulses or audible sounds, or a combination of these two forms. As the user navigates through the menu system by sequentially selecting from available options, the NV cues are generated so that the user can sense a location within the menu system. The different NV cues may be associated with the availability of certain selected options, the selection of them, or organized in a manner analogous to the manner in which the options themselves are organized.

Abstract: A system and method for determining the progress and position of a pedestrian. The shoes of the user are each provided with communicating sensors. The sensors sense when a step has been taken and communicate with each other through Bluetooth, 802.11b, or some other such short-range wireless protocol. This communication includes a distance measurement, and the distance between sensors is calculated and stored with each step, the sensors being in communication with a central processor for this purpose. The sensors also determine their own orientation and their orientation relative to the other sensor, communicating this directional information to the central processor as well. The direction information is used to calculate the direction of travel and, combined with the accumulated distance measurements, the position of a user.
