The multitoe interface of Augsten et al. [
4
] is based on the optical sensing of foot-floor
contact regions captured through back-projected translucent floor plates using the frustrated total
internal reflection method (image reproduced from [

])

The iGameFloor interface of Gronboek et al. [
12
] uses vision-based limb tracking on a
rear-projected interactive floor comprised of back-projected translucent floor plates (image repro-
duced from [
12
])
has been found to depend on the interaction technique adopted or other factors.
Using precision control strategies, single-pixel accuracy in finger-based touch-screen
interaction has been demonstrated [
3
,
27
], and similar techniques may be effective
for enhancing the precision of control with the feet (Figs.
17.5
,

).
