“…Dearman et al compared foot switches on a pedal to screen touch, device tilt, and voice recognition in text editing tasks [6]. Garcia et al looked at how performance evolves as users learn to operate a foot joystick and a hand trackball [7]. Table 1 summarizes the results of these studies.…”

“…In particular, unlike previous work that used trackballs [5], pedals [6], and foot mice [7], we wished to explore unconstrained feet movements. This removes the need for a physical device (as well as the related foot-to-device acquisition time) and provides a wide range of interaction possibilities (analogous to the ones available from a touchscreen over a mouse).…”

Abstract. We characterise foot movements as input for seated users. First, we built unconstrained foot pointing performance models in a seated desktop setting using ISO 9241-9-compliant Fitts's Law tasks. Second, we evaluated the effect of the foot and direction in one-dimensional tasks, finding no effect of the foot used, but a significant effect of the direction in which targets are distributed. Third, we compared one foot against two feet to control two variables, finding that while one foot is better suited for tasks with a spatial representation that matches its movement, there is little difference between the techniques when it does not. Fourth, we analysed the overhead caused by introducing a feetcontrolled variable in a mouse task, finding the feet to be comparable to the scroll wheel. Our results show the feet are an effective method of enhancing our interaction with desktop systems and derive a series of design guidelines.

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

“…Previous work that evaluated the physical capabilities of the feet concluded that the feet can be from 1.6 [12] to 2 times [9] as slow as the hands, but this difference can be reduced with practice [7]. Researchers have demonstrated that the feet are suitable for tasks such as mode selection [14], non-accurate spatial tasks [12] and performing secondary tasks whilst the hands are busy [1].…”

In this paper we present an exploratory work on the use of foot movements to support fundamental 3D interaction tasks. Depth cameras such as the Microsoft Kinect are now able to track users' motion unobtrusively, making it possible to draw on the spatial context of gestures and movements to control 3D UIs. Whereas multitouch and mid-air hand gestures have been explored extensively for this purpose, little work has looked at how the same can be accomplished with the feet. We describe the interaction space of foot movements in a seated position and propose applications for such techniques in three-dimensional navigation, selection, manipulation and system control tasks in a 3D modelling context. We explore these applications in a user study and discuss the advantages and disadvantages of this modality for 3D UIs.
