Novel Modalities for Bimanual Scrolling on Tablet Devices

Part 1: Long and Short PapersInternational audienceThis paper presents two studies investigating the use of novel modalities for bimanual vertical scrolling on tablet devices. Several bimanual interaction techniques are presented, using a combination of physical dial, touch and pressure input, which split the control of scrolling speed and scrolling direction across two hands. The new interaction techniques are compared to equivalent unimanual techniques in a controlled linear targeting task. The results suggest that participants can select targets significantly faster and with a lower subjective workload using the bimanual techniques
