| Abstract | This paper introduces a new concept for the area of user interfaces called Perceptual Cursor. As opposed to the regular cursor, which is by definition an item to mark a position of applied control, Perceptual Cursor also serves a purpose of providing the visual information about the perceived sensory data governing the cursor control. By fulfilling two purposes in one object, Perceptual Cursor eliminates one of the major problems in designing hands-free user interfaces - that of the absence of “touch” or tangible feedback in these interfaces. The paper also introduces a number of propositions related to cursor design that need to be followed when designing a hands-free cursor-controlled system and describes two specific designs for the Perceptual Cursor that are currently being tested with the hands-free addition of the Perceptual Vision Interface Nouse. |
