     How do I manipulate the mouse cursor with scanning?


  While WiViK does provide scanning mouse emulation, the preferred approach is to take advantage of our innovative desktop scanning. Generally, mouse scanning is not recommended.

With a Windows environment, users are expected to use a pointing device to manipulate GUI objects such as icons, windows, menus, buttons, scroll bars, lists, and text. However, there is a basic problem converting binary (on/off) or discrete actions into equivalent continuous actions normally associated with direct desktop manipulation. Many other onscreen keyboards require you to move the mouse cursor in a scanning fashion and choose button actions. Practically, this approach is tedious and time-consuming.

WiVIK, through a series of keys located on the bottom row of scanning-style keyboards, applies scanning directly to dynamic desktop objects such as the Start menu, application menus, the text cursor, windows, scrollbars, and task switching. Thus, for example, the text cursor can scan across text directly, or a window move itself in a scanning steps. The advantages are:
- Fewer switch activations
- More ‘direct’ and faster than mouse emulation
- Fewer attention shifts
- Focus attention on end task

Please read the User Guide chapter on Scanning the Desktop, pages 32-39. (A description of scanning mouse emulation is included.)
