The following are the basic finger gestures for operating RAY:
• TOUCH: RAY is operated by using your fingertip(s) to touch its screen. For
best results, try to position your finger approximately in the center of the
screen. When you touch the screen, RAY vibrates slightly. If you are touching
outside of the touch screen surface (meaning too far away from the center of
the screen), then a special cancellation tone is sounded and your touch is
ignored. If RAY does not vibrate or beep, then RAY is powered off (in this
case, press the ON/OFF button to power it back on).
• SLIDE: Sliding means to move your finger a little in any direction and then
stop, without lifting your finger off the screen. The slide only needs to be long
enough for RAY to recognize the movement, but not too long to go out of the
screen area. After you slide your finger far enough, RAY says the name of an
option. If you slide your finger too far out of the touch screen area, then you
hear a cancellation sound and no selection is made.
• SELECT: An item is selected in RAY when you lift your finger off the screen
after RAY says
