Abstract Title: Decreasing Hand Occlusion On Touch-Screen Tablet Devices: Influencing Hand Orientation with Tablet Tilt Angle
Abstract: As students use touch-screen tablet devices, their hands can occlude regions of the screen, potentially impacting their learning experience. Here, we present results from an exploratory study of hand orientation and occlusion among primary school students using touch-screen tablet devices. Specifically, we investigated hand orientations, amount of occlusion, and the effects of tablet position (on table or lap) and tilt angle (flat or tilted) on students preferred hand orientations when using a touch-screen tablet device. From 15 interviews with 5th–7th grade students, we found five hand orientations, corresponding to a range from high to low occlusion. Tablet tilt angle seemed to considerably impact students preferred hand orientations. Based on these results, we suggest that encouraging students to work on tablets with a moderate tilt angle (30-45 degrees), rather than lying flat on a table, could significantly decrease occlusion and increase the effectiveness of touch-screen tablet devices for student learning.
