Knobs, buttons, levers, and touch screens have dominated the controls world by being the primary way that a user interacts with an embedded device. These tactile interfaces aren't the only way to interact with a device. In recent years, new sensors and technologies have created opportunities to create tactile-less interfaces that rely on hand movements and gestures. These gesture-based controls can be a far more intuitive and natural way to interact with a device.
In this chapter, we will examine how to integrate a gesture controller into an embedded device that allows us to control it using gestures.
The following topics will be covered in this chapter:
- An introduction to gesture controllers
- Gesture controller requirements
- Gesture controller hardware and software design
- Constructing a gesture controller
- Testing gesture controller applications...
