For example, there are many games, especially for tablets,
that allow two users to play simultaneously. When individual
scoring or control is needed, interfaces most typically
have a split view. However, this limits game design possibilities
and decreases the available screen real estate for
each player. Using Capacitive Fingerprinting, it is possible
for two players to interact in a common game space. To
demonstrate this, we created a “Whac-A-Mole” game [34],
seen in Figure 1. Targets appear out of random holes; players
must press these with their fingers before they return
underground. Each time a player successfully hits a target,
he gains a point; individual scores are kept for each player
automatically and transparently for each user.
