Effects of Footpad Slope, Movement Direction and Contact Part of Foot on Foot-Based Interactions

Feet cannot perform tasks as quickly and with much dexterity hands. However, due to the heavy workload placed on hands, there is potential for feet replace or assist them . In order use more effectively, this study aims find ways increase speed accuracy of directly touching a touchpad while in seated position. The investigates effects three factors: slope touchpad, direction foot movement, touch area used. Regarding found that most effective both was at 30° angle right when front set 0°. 0° 60° angles showed similar efficiencies, but were lower than angle. also using big toe resulted best speed, accuracy, subjective satisfaction. index second-best option, ball least accurate slowest option. Lastly, an 15° work efficiency compared 7° These findings can serve guidelines designing interfaces.
