Analysis of Properties of an Active Linear Gesture Sensor

“…However, typical interfaces, which are oriented towards the continuous gestures, are able not only to notice a swipe but also to estimate a current location of a hand/finger. The position standard deviation errors in one such interface are equal to 0.03 cm, 0.02 cm, 0.01 cm in the x, y and z axes, respectively [15]. The accuracy of hand localization in the proposed sparse sensor was examined only along the x axis.…”

“…They have also described a two-emitter, six-receiver prototype sensor for virtual reality glasses, which detects swipes and push/pull gestures [14]. Chuang et al have mounted emitter-receiver pairs in the corners of a mobile device that enabled to recognize a hand position basing on trilateration [15]. Tang et al have proposed a linear, 10-detector IR transceiver, as an implementation of the virtual computer mouse, which tracks a hand position and can detect three click gestures [16].…”

“…Some interfaces handle continuous gestures, e.g. [15]. In terms of HSI, the system navigated by such an interface reacts while the gesture is performed.…”
