Abstract
A unique challenge for the Orion Crew Exploration Vehicle is the need for a novel cursor control device (CCD) that allows the crew to interact with display formats while seated and restrained. Display formats will contain "controllable elements" that will be used for input by astronauts, and will most likely not be laid out in a rectilinear grid. A four-way "caged" castle switch on the CCD was designed to travel only to controllable elements toward decreasing erroneous cursor movements. The ability of the four-way castle to intuitively navigate the cursor from a user perspective is a vital consideration. A cursor expectations study was conducted to understand dominant user expectations for CCD movements when controllable elements are not arranged on a rectilinear grid. Algorithms were developed that governed cursor movement in such a way as to match the: dominant user expectations, to support the development of user mental models for cursor behavior, and to guide designers when laying out display formats.
