the concept of “sliding windows” (continuously monitoring a fixed or
variable length of motion stream for the existence of a meaningful
gesture) may be able to solve this problem.
e segmentation problem is more challenging for gesture recogni-
tion because, in the case of voice recognition, the background noise
may be low and the detectable spoken inputs intermittent, meaning
that the voice-recognition mode can be automatically activated by
sound detection (e.g., sound intensity is greater than some thresh-
old). Touch gesture is the same. In most cases, it is natural to expect
touches only when a command is actually needed. us a touch sim-
ply signals the start of the gesture input mode. As for 3-D motion
gestures, users usua ...
