Exit_Point_Mode (28H) (()

Command Description

When the touch mode is set to Exit Point Mode by sending the

Exit_Point_Mode (28H) command, the touch system sends a Touch

Coordinate Report to the host when the stylus leaves the touch active

area. The stylus must have already entered the touch active area before

the Exit Point touch can be detected.

Exit Point Mode is used for menu selection. It lets the stylus enter the

touch active area and move to the desired target without activating a

selection until the stylus leaves the touch active area. This can be

advantageous for small or very complex screen designs, or for

educational purposes when the user is not familiar with the selections.

Report Format

See Coordinate Reporting (23H) in this appendix for the format of the

Touch Coordinate Report and Non-Contiguous Coordinate Report.

Example

See Coordinate Reporting (23H) in this appendix for examples of the

Touch Coordinate Report and Non-Contiguous Coordinate Report.
