ABSTRACT:
Enhancing access for physically impaired users to selectable items in a hierarchical arrangement through the preliminary testing of a user response time in moving a user controlled on-screen pointer from a start point over an equal distance to each of a plurality of said selectable items of different sizes in combination with implements responsive to this preliminary testing means for sizing a set of items in said hierarchical arrangement to provide said user with enhanced access to said items in said set.Access for the physically impaired is even further enhanced through preliminary testing of a user response time in moving a user controlled on-screen pointer from a start point over an equal distance to each of a plurality of said selectable items wherein each item is located within a region of different item layout spacing, in combination with an implement responsive to said preliminary testing means for spacing a set of items in said hierarchical arrangement to provide said user with enhanced access to said items in said set.There is a further provision for listening for predetermined events in the operation of said display system and means responsive to said predetermined events for triggering said means for preliminary testing during said system operation. Likewise, there are means for listening for predetermined events in the operation of said display system in combination with means responsive to said predetermined events for triggering said means for preliminary testing during said system operation.
