Gestures
EDN Magazine has published a comprehensive feature story by its technical editor Robert Cravotta, on how gesture interfaces are evolving in complexity and capability, adding new dimensions to the control of electronic devices from game systems to mobile phones to industrial systems.

Summary

  • Many of the gesture interfaces we see in innovative products can trace their roots back several decades.
  • Gesture interfaces find more use than just in games and infotainment devices; they also control systems in industrial and medical environments.
  • Much of what makes a gesture interface reliable and useful, such as inferring or predicting intent, is not obvious to the user.
  • The success of an interface is in how well it handles uncertainty with the user.
  • Devices with modern interfaces must consider how to manage wireless and network connectivity between systems so that they appear as one system to the user.
