Gesture & Non-Gesture ToF Applications

Generally speaking, 3D Time of Flight uses can be categorized into Gesture and Non-Gesture. The Gesture applications emphasize human interactions and speed; while non-gesture applications emphasize measurement accuracy.

Gesture applications translate human movements (faces, hands, fingers or whole-body) into symbolic directives to command gaming consoles, smart televisions, or portable computing devices.

For example, channel surfing can be accomplished by waving of hands and presentations can be scrolled by using finger flickering. These applications usually require fast response time, low- to medium-range, centimeter-level accuracy and power consumption. The Microsoft Kinect 2 uses Time-of-Flight sensors for gesture interactions.

ToF 3D depth sensors have so many uses in non-gesture applications as well as highlight further on. The automotive industry is further ahead of the drone industry in using ToF depth ranging cameras.

For instance, in automotive, a ToF camera can increase safety by alerting the driver when it detects people and objects in the vicinity of the car and in computer-assisted driving. In robotics and automation, ToF sensors can help detect product defects and enforce safety envelopes required for humans and robots to work in close proximity.

Some of the non-gesture ToF applications are scanning for objects, indoor navigation, outdoor navigation, obstacle detection, collision avoidance, tracking objects, volumetric measurements, reactive altimeters, 3D images photography, augmented reality games and much more.
