“…Our initial observations [9] indicated that sliding the finger across the screen during swabbing appeared to dampen deviation, but this observation has not been confirmed empirically. Neither has swabbing been compared to tapping, the basic touchscreen interaction technique.…”

Elderly users suffering from hand tremor have difficulties interacting with touchscreens because of finger oscillation. It has been previously observed that sliding one's finger across the screen may help reduce this oscillation. In this work, we empirically confirm this advantage by (1) measuring finger oscillation during different actions and (2) comparing error rate and user satisfaction between traditional tapping and swabbing in which the user slides his finger towards a target on a screen edge to select it. We found that oscillation is generally reduced during sliding. Also, compared to tapping, swabbing resulted in improved error rates and user satisfaction. We believe that swabbing will make touchscreens more accessible to senior users with tremor.

“…It has also been used with cognitive impaired people and mouse interaction [19]. As well as swabbing, drag-and-drop has been used for target acquisition, digit and text entry tasks with pen [5] and fingers [12,20].…”

“…Drag-and-drop interaction on touchscreen has been proposed to motor impaired users [5] and older users with tremor [12,20] because the continuous contact with the screen have an effect on finger oscillation, helping users to increase the accuracy. It has also been used with cognitive impaired people and mouse interaction [19].…”

This study investigates the accuracy of drag-and-drop interaction for older adults by analyzing the number of supplementary attempts for positioning a target during the execution of tactile puzzle games on two different screen sizes, tablet and smartphone, with finger and pen interaction. 24 older subjects (aged 65 to 86) participated of the experiment. The results showed that there is a significant effect of the interaction techniques during interaction on smartphone. Subjects were more accurate during pen interaction on both screen sizes. Age effects were significant but subjects aged 80 years old or oldest sometimes performed better than subjects aged 70 to 79 years old, especially during pen interaction. This study shows that drag-and-drop is an efficient technique for moving targets even on small touchscreen devices and pen interaction may help older users to execute more accurate drag-and-drop interaction on touchscreen devices.

“…This gesture of interaction has been studied to improve text entry tasks for older users with tremor [16], [17]. During mouse interaction, dragging elements helps to track the cursor on the screen and it has been evaluated for cognitive impaired users [18].…”
