Pursuit of perfect human-machine interface gesture control products came out in 2009

for the design engineers of consumer electronic products, the pursuit of perfect human-machine interface is endless. Now, including Panasonic, Hitachi, Toshiba and other consumer electronics brands, big 5, PC microcomputer measurement, computing, digital display results, printing plants, are developing large screen TVs controlled by "gestures", that is, users can operate the TV, turntable, or switch browsing windows as long as they wave their hands, without using a remote control. Such products are expected to be available in 2009

the consumer electronics industry has spent a lot of time on human-computer interface technology, including the old-fashioned infrared remote control, mouse, keyboard, game console handle, trackball, screen knob/wheel, and magic wand with accelerometer. Also unforgettable is the "Bob" interface with a bunch of cartoon characters launched by Microsoft for windows 3.1 in 1995. Finally, the voice control user interface is touted as a new generation "UI Model"

then why does the industry need gesture controlled TVs? There are two main reasons; First, the remote control becomes increasingly complex and difficult to operate for users; Secondly, the existing large-size TV can display multiple windows on one screen, so a more intuitive method is needed for those who consume jjf101⑵ 006 "terms and definitions of force value and hardness measurement", and there are no terms specifically for dynamic torque to browse

many manufacturers have shown samples of gesture controlled TVs, allowing users to rotate images by changing the action of their hands (such as circle, left and right shaking, back and forth shaking), or move the window, zoom the video on the screen, and so on. For example, in the figure below, Hitachi's gesture control TV can turn on the power by simply waving your hand, and you can use up and down gestures to operate the screen menu, or circle in the air to adjust the volume

hitachi's gesture control TV

sensor is the basic technology to realize the gesture control TV interface. For example, Panasonic has developed an image sensor device, which is composed of near-infrared led, special CCD sensor and FPGA. The device senses gestures by measuring" time of flight (the time it takes for the light emitted by the near-infrared sensor to reflect to the CCD image sensor) ". p>

hitachi's gesture controls the image sensor inside the TV, and the best recognition distance is 2~3 meters from the user to the TV. Can gesture control TV create a better and more intuitive user interface? When relevant products come out in 2009, we can know whether consumers are willing to let go of the remote control
