Carnegie Mellon University Research Team Developing New Wearable Device System [Full Text]

Scientific and technological developments in recent years, with the popularity and widespread use of mobile Internet, smart wearable device industry rapid development, has become one of the fast growing worldwide high-tech market, it will undoubtedly be the next hot mobile terminal industry. At present, it seems that the sense of freshness brought to the people by mobile terminals represented by smartphones is waning. The masses that have been thoroughly penetrated by digital products over the years need new playthings.

Wearable smart devices embed multimedia, sensors, and wireless communication technologies into some flexible devices worn by people in everyday life, such as glasses, watches, and wristbands, to strengthen the interaction between people and devices, but at the same time of rapid development. Inevitably, the wearable smart device market has experienced serious homogeneity and ambiguity in positioning. Taking a smart watch as an example, IDC data shows that consumers' curiosity on wearable smart devices has declined and shipments of various manufacturers have decreased. The main reason is that the functions are simple and the utility value is not high. The root cause of the above phenomena is the lack of innovative technologies to achieve product iteration and upgrade.

To break through the status quo in this industry, a domestic technology company and the United States Carnegie Mellon University reached a strategic cooperation intention to jointly explore the application of gestures and physical manipulation in real consumer life, based on Carnegie Viband technology to determine and analyze human body language, The frequency and amplitude generated by the gestures are learned by the robot intelligently, and the robot's automatic learning mechanism is formed at the software end, thus forming a brand-new interaction mode between the terminal device and the human. The ViBand system is a powerful combination of smart watches, and it is expected to solve the difficulties faced by smart wearable devices from the technical level and create a new generation of smart mobile terminals.

The ViBand system developed by the Carnegie Mellon University research team uses high-fidelity bio-acoustic sensing using commercial smart watch sensors. By analyzing the characteristics of the bio-acoustic signal emitted by the user, the ViBand system allows the watch to recognize different hand movements such as rubbing fingers, scratching, tapping, tapping, and the like. Each action can be used to perform specific tasks after being processed by the ViBand system, such as adjusting the volume of the computer by rotating the arm, or by turning a finger to control the switch of the light and television. Not only that, the ViBand system can also recognize the sound signals emitted by hand-held items.

At present, Carnegie Mellon University cooperates with many international famous brands. Among them, FIG (Future Interfaces Group) is an interdisciplinary research laboratory of the Human-Computer Interaction Research Institute of Carnegie Mellon University, where Viband, AURASENSE, TOMO, etc. were born. Dozens of new sensor and interface technologies, the purpose of these studies is to provide humans with more comfortable and convenient human-computer interaction. Many high-tech R&D companies, including Google, BOSCH, and Intel, are supporting Carnegie Mellon University and maintain close project partnerships with the FIG laboratory. Carnegie said that the selection of a number of technology companies is not only due to the combination of technology and philosophy, but also due to the high recognition of their Cast products. Harrison, the head of the ViBand laboratory, admitted: “Smartwatches can only fit with an inch of screen. How can we enhance human-computer interaction without large screens? This is what we studied in the last five years.” And Carnegie Mellon University A number of scientific and technological cooperation just solved this problem.

All in all, after looking forward to strong alliances, we can bring different smart watch experiences to everyone, inject fresh blood into the wearable smart device industry, and open up broader development prospects. It is understood that Viband has been supported by foreign foundations (Google Foundation and Qualcomm behind the foundation). Follow-up also expects more application scenarios and technology products based on the Viband system.
