Learning to Drag: The Effects of Social Interactions in Touch Gestures Learnability for Older Adults

Abstract

Considering the potential physical limitations of older adults, the naturalness of touch-based gestures as an interaction method is questionable. Assuming touch-based gestures are natural, they should be highly learnable and amenable to enhancement through social interactions. To investigate whether social interactions can enhance the learnability of touch gestures for older adults with low digital literacy, we conducted a study with 42 technology- naive participants aged 64 to 82. They were paired and encouraged to play two games on an interactive tabletop with the expectation to use the drag gesture to complete the games socially. We then compared these results with a previous study of technology-naive older adults playing the same games individually. The results of the comparisons show that dyadic interactions had some benefits for the participants in helping them to become comfortable with the drag gesture by negotiation and imitation. Further qualitative analysis suggested that playing pairs generally helped learners to comfortably explore the digital environment using the newly acquired skill.
