Exploring Accessible Smartwatch Interactions for People with Upper Body Motor Impairments

Smartwatches are always-available, provide quick access to information in a mobile setting, and can collect continuous health and fitness data. However, the small interaction space of these wearables may pose challenges for people with upper body motor impairments. To investigate accessible smartwatch interactions for this user group, we conducted two studies. First, we assessed the accessibility of existing smartwatch gestures with 10 participants with motor impairments. We found that not all participants were able to complete button, swipe and tap interactions. In a second study, we adopted a participatory approach to explore smartwatch gesture preferences and to gain insight into alternative, more accessible smartwatch interaction techniques. Eleven participants with motor impairments created gestures for 16 common smartwatch actions on both touchscreen and non-touchscreen (bezel, wristband) areas of the watch and the user’s body. We present results from both studies and provide design recommendations.
