No more fighting over the remote! In the not-so-distant future, you may be able to control your TV and other electronic devices with a wave of your hand or flick of your wrist. You will literally be able to interface directly with the electronic world.

News You Can Use

  • The technology needed to control electronic devices with body motions has already been developed. Currently, it requires you to wear some type of sensor or to have cameras detecting your motions in order to interact with your electronics.
  • But technology is being developed that won’t require anything but gestures to control everything from the lights in your room to the computer on your desk.
  • To get a feel for what it might be like to interact directly with electronic devices, watch this short video:


What Do You Think?

With the links below, learn more about gesture-recognition technology. Then answer the following questions.

  1. Gesture recognition by Wi-Fi signals (called “WiSee”) is similar to Xbox Kinect. Xbox Kinect uses cameras to recognize gestures. How is WiSee different?
  2. WiSee technology uses a standard Wi-Fi router that has been adapted to function as a receiver. How does the adapted receiver pick up gestures?
  3. A potential problem with WiSee technology is the possibility of neighbors or hackers using gestures to control the electronic devices in your home. How could this problem be prevented?
  4. What do you think? How might people’s lives change if they could directly interface with their electronic devices using WiSee technology?
