Finger and Palm Interactions in a Multi- Touch Card Game Christian Reichart Course: Interaction Engineering Winter semester 2014/15 Instructor: Prof. Dr. Michael Kipp
Real Card Games - Shuffling - Dealing out cards - Drawing - Playing out cards - etc.
Real Card Games Personal vs. Public information → essential in most games
The Goal Bringing those elements of play to a multitouch interface PKR for iOS
Prototype Processing Framework 10-inch Android Tablet
Prototype - Players score points by putting out cards - 20 cards in play - 5 cards in hand
Prototype - Palm is simulated - 3 knobs with aluminium foil
Interaction Techniques Dragging - Used to draw a card - Card follows finger
Interaction Techniques Palm Hiding - Used to see own cards - Blocks sight of opponent - Cards “flip” again, when palm is released
Interaction Techniques Pushing - Used to play a card - card is “pushed” towards center
Interaction Techniques Multi-Finger Wiping - Used to shuffle the cards - Progress bar shows “amount” of shuffled cards - User can stop at any time

Related Work Recognizing palm with multitouch Classifying Hand Shapes on a Multitouch Device → Light-based multitouch → Recognition may take several seconds
Conclusion - Multi-touch great for finger based natural interactions - Capacitive screens struggle with palm recognition - Would be great to test with a bigger screen (e. g. multi-touch table)
