Horizontal scrolling is possible using the base of the VersaPad®. The driver allows the VersaPad® to track the current status of a laptop screen. When the screen is rotated, the coordinates adjust to allow for standard operation in a modified position. A general bezel mounting method is available on the VersaPad® module. Mechanical installation of the VersaPad® module has many critical features that must be considered for mounting. Care should be taken to avoid inadvertent pressure on the top membrane of the sensor as such pressure could be confused with a user’s external touch. The membrane is supported at its edge by an internal spacer. Parts used to capture the VersaPad® module must not make contact with the sensor inside the electrically active area. The USB and PS/2 VersaPad® are available in a flat flexible cable interface (FFC) or a wire to board header connector interface.
