Many homes have large LED TVs and Blu-ray players. This is the current generation of technology deployed in households around the globe. However, all this technology is using old techniques for controlling devices, including remotes and push buttons on the devices themselves. Other personal devices, such as phones and tablets, have moved past the old model of input peripherals and use touchscreens and motion gesture. For example, the Xbox One and PlayStation 4 have motion-tracking cameras that can utilize gesture recognition to play and control the console, along with speech recognition for additional input.
Not every household will have an Xbox One and motion gesture input. Many companies are aware of this and are planning on creating devices for the sole purpose of gesture and voice recognition. These devices would be attached to televisions or possibly integrated into them during the manufacturing process. One such company is PointGrab. Its PointSwitch product, which uses common gestures to control touchscreen interface devices, will let users control home appliances. The user points a finger at the desired device. The device, tracking the direction of the user's eyes, will find the device, which the user then can control through various gestures. The user could point at a light and then move a hand up or down in order to dim or brighten it. The PointSwitch can detect gestures up to 15 feet away and in the dark.
The device (featured in the video below) is being made to work with appliances such as televisions, door locks, and air conditioning or heating systems. PointGrab is set to debut the product at CES 2014.
