Screen frame with raised tactile portions

摘要

A tactile aid for use with a display screen having touch-sensitive features, including a frame having at least two sides, the frame configured to substantially coincide with a perimeter of the display screen. The frame includes a first tactilely distinguishable area along a first side of the frame and a second tactilely distinguishable area along a second side of the frame substantially orthogonal to the first side of the frame. The tactilely distinguishable areas are positioned such that a first line passing through the first tactilely distinguishable area and orthogonal to the first side of the frame and a second line passing through the second tactilely distinguishable area and orthogonal to the second side of the frame intersect at a point on the display screen corresponding to a location of a first touch sensitive area of the screen.
