The present invention relates to a system and methodology to assist users with data access activities and that includes such activities as routine web browsing andor data access applications. The system includes a receiver such as a GPS receiver for receiving GPS signals and a processor for determining position from the received GPS signals. The specifying unit analyzes a T1-valued image and specifies colors to be assigned to each pixel on the basis of T1 values converted from pixel values of each pixel and the corresponding color table. The method further includes, while the modal region remains displayed, recognizing a touch gesture from a user’s second hand directed at the display within the modal region and performing an action on the display based upon a mapping of the touch gesture. The target state transition matrix and the target error covariance matrix are propagated. Tangs are stowed within the body of a grip and deployed through one of a number of mechanisms, including spring-loaded and non-spring loaded mechanisms.
