Multi-touch technology and finger-gesture interaction are becoming increasingly popular. While manufacturers advertise this new interaction paradigm as easy and to use, it remains unclear whether it indeed facilitates interaction, especially for older users with their special knowledge, needs and capabilities. The present work investigates which gestures are intuitive to older and younger users for a range of common interaction tasks on a mobile device. We found that older users are less coherent in their proposed gestures, use fewer fingers and generate more symbolic gestures.
