While the use of untouch in the keyboard demo allows a higher density of touch
zones, it does require training, although only a few seconds worth. With the
public, you do not have any opportunity for training. Because Point Mode is

Touch Piano
Play the piano right on the screen.
You cannot touch more than one note at a time.
Touch Maze
Find your way through this maze.
Touch "Start" and slide your finger down the paths. If you hit the hedges, slide
back to the center of the path and continue. As you move through the maze, you

they form new stacks. You may touch these stacks to reduce your bet. Touch
"DEAL".
After the cards are dealt, touch "Hit," "Stand," or "Double". Splits and insurance
are not implemented.
Touch "Wager" to play again.
Touch X,Y

modes the Elo drivers make available to programmers.

origin is in the upper left or lower right corner. Touch "Untranslated" to switch the
driver into Translated Mode. Now the coordinates are adjusted by the driver to
match the screen resolution. A cursor appears which can be moved to 10,10.
Stream Mode outputs coordinates continuously as long as the screen is touched.
Point Mode only outputs a point when the screen is first touched. Point Mode with
