[PConline Information] I believe many people suspect that the smartwatch's screen is too small and inconvenient to manipulate. The good news is that this situation will soon change. According to foreign media reports, NEC recently demonstrated a crazy new augmented reality keyboard technology in Japan: allowing users to control smart watches worn on their hands with Google Glass-style head-mounted devices. The ARmKeypad pairs augmented reality glasses with smart watches and "projects" the keyboard to the wearer's arm. After that, the glasses will detect the pressed Augmented Reality button and recognize it as the information input on the watch. The wearer's arm equals the virtual keyboard of the smart watch. Not surprisingly, ARmKeypad from NEC is being sought after by factory workers. However, this convenient technology should also benefit ordinary consumers. At present, no company can really solve the problem of inputting wearable technology. No company can find a way to efficiently interact with a small screen on a wearable device. Last week, the Wareable website reported a new input method for the TouchOne Keyboard for smart watches. In October, Wareable also reported on Keybod, an alternative keyboard input method that covers the entire human body. It can be said that there are some crazy concepts in the field of wearable device input, so don't think NEC's ARmKeypad based on augmented reality technology is a fantasy. It is reported that NEC will push ARmKeypad to industrial workers in 2016. In fact, the ARmKeypad's mode of operation is similar to that of Fujitsu's 2014 display of smart support for air writing. The concept of wearable input technology and crazy smart helmets from Japan seems to be endless. Comment: NEC has pulled back the dying Google glasses again.
