With the adjustment of automation production line, the originality of the unit area is increased, and more and more people have begun to accept such a fact. As mobile integration has more, people have a increasingly dependence on mobile phones. The current mobile phone is not an entertainment equipment, communication terminal, mobile office platform. It is more like an "organ" of the Internet, as long as you live in the Internet era, the phone is essential. Can wear smart devices seem to have such luck, now wearing smart markets are experiencing a cold winter, and major brands are experiencing the long and hard process of emerging technologies, new species to civilian commodities. Core technology research and development capabilities And the capability of core technology is to develop these products, whether the brand can be smashed, and see the key to the dawn.
"Smart watch can be more intimate with users"
Dr. Xiao Bo, Mellon University Human Institute, recently accepted our interview, his Future Interfaces Group is engaged in research and development of multiple human-machine interaction technology, including Viband technology, this technology may It is possible to bring a lot of new revelations in addition to products that can wear smart devices.
According to Xiao Bo, "CMU (Carnegie Melon University) is working with many well-known brands, including Intel, Google, and we hope to change some fun in the next few years of human-machine interaction, have not been Cognitive technology, and commercialize these technologies and sent to everyone through the form of the product. "
(Person in charge of Viband Technology Project: Xiao Bo)
In addition to VIBAND, Xiao Dr. and his team have been focusing on Direct (High-precision Infrared Touch Tracking Technology), Skin Buttons (low-cost laser skin touch technology) research, his FIG also born included Aurasense, Tomo et al. Dozens of new sensing and interface technology, including everyone's well-known Huawei mobile phone pointer screen capture technology, the prototype of this technology is Finger Sense, which is developed by FIG and QEEXO, and the technology is sold to Huawei.
"In 2010, the FIG entered the way to determine the user behavior through Teslatouch technology. In 2016, Fig found a technology that changed the arm surface to touch screen, the birth of each prototype technology, It means that we take important steps on the path of virtual touch. Just like puzzles, these technologies have evolved and related applications of cross-technical platforms, they will be used as a scene of future human-computer interaction. "
Based on the technique of existing and research, the FIG will greatly improve the equipment interaction capabilities without increasing the conditions of the new sensor without changing the watch, the equipment structure such as a watt, does not increase the conditions of the new sensor, change the intelligence. Watch, the bracelet is no longer only written, see time, receives the function positioning of the newsletter, through the logic of the user's gesture, skin slight rubbing, arm jitter and other behaviors, bringing users more than mobile phones Get close to the sensitive interactive experience.
"VIBAN wants to bring the user differentiated experience instead of trouble"
"Because smart watch and wearable devices are wearing us, they make them very special, especially in terms of convenient input information and interaction. Smart watch wear on the wrist, can become an ideal biological acoustic signal capture equipment. Viband technology future Based on the CAST series of products to achieve further research and exploration, achieving specific media (such as skin, rough wall) gesture, biological acoustic input sensing, object identification, body data transmission several parts. Based on CAST smart watch existing, we It will expand more virtual touch planes; use biological acoustic signals, we can distinguish your movement, clapping, grasping, tapping, etc.; through the frequency of vibration of objects, we can identify objects contacted by users, such as toothbrushes, chainsaws, Guitar, etc., through the biological acoustic signal of the user (wrist, ear and other physical signals), we can provide the applications and services needed by users, and the form is similar to the osteoconduct technology. In summary, Viband gestures and intelligent wear users The equipment interaction logic is combined, and it can create differentiation but not to bring the use of trouble to use the use of troubles, bringing the user's new experience. "
Through Dr. We know that the secret of Viband technology is to increase the sensor sensor induction range from 100 Hz to 4000 Hz. It is understood that the current smart watch sensor usually limits the sampling rate at 100 Hz, which is for the main functions of smart watch / bracelets, such as detecting the direction of the watch (raising the arms, waking the device screen), tracking the number of steps (~ 2Hz) ), It is enough. However, if the sampling rate is increased to 4000 Hz, it will make the "nerve" of the smart watch, and any fine action or physical state is captured. By analyzing the analysis of these signals, it is determined that the state is in place. Static, it is cycle, is a walk, it is exercise, it is a rest, etc.
During a long time and repeated test verification, the FIG will preset different signal data in the solution, and selectively provide feedback mechanisms that do not bring trouble to users, such as scratching heads and arms. Two action is similar, but the resulting signal is different, and when the user wants to pass a phone through the sway arm, the system will block the frequency of the flex head, which avoids erroneous operation.
As the above example, we can imagine that by preset or custom actions in advance, you can turn on TV with a watch, and you can turn on TV. If you take it back, you will change it. Will this experience will not be very wonderful?
In addition, the accelerator can also identify biological acoustic signals generated by different handheld power tools, such as food, electric toothbrush, guitar, and the like. Try to think about this scene. When you take food in your hand, the smart watch can display the heat of the related food on the screen; when the user starts to brush the teeth, it will automatically count down, and ensure that you don't exceed normal. Brushing the teeth; when you give guitar tuning, it can identify the adjustment of the position to ensure that you don't run sound. Will this experience be interesting?
"To give the user"
While we are amazing, "there is such actions", there will be some worries: how can the sensor so sensitive, how to eliminate unnecessary data noise and whether it will increase power consumption?
Xiao Bo said that "in solving unnecessary interference and data noise, the technology is not a problem, the traditional microphone signal input can provide even higher sampling frequencies (typically 44.1kHz), however, the microphone is usually designed to capture The vibration in the air, not contact vibration, which means that the useful signal must be separated from the environmental noise of the background, compared to the micro-acoustic information collection method only collects signals with physical interaction with the body, so it will not be subject to The impact of noise. This means that it will not increase power due to noise. "
"However, based on Viband, it is indeed a small power consumption to the battery. We have taken two ways to solve power consumption problems: 1. Users can freely set whether Viband is turned on, open will be more sensitive, you can do more Personalized interaction, but is limited to battery technology and watch space, smart watch-to-pending opportunities will be affected, and if you turn off, you can only do some simple operations, but will save more. 2. In depth learning and system interactive logic In the process of constructing, more gesture actions that are simple and not caused by information confusion are interactive, such as starting fingers, two fingers slightly rubbed, so that users have other unconscious or frequent action will be ignored. "
"Uncertainwords will not be the next QEEXO, but this company is not just doing a watch"
A number of technologies have reached a cooperation intention with CMU earlier. When asked if the upcoming CAST series products will be equipped with a full set of Viband technology, Xiao Shi answers this: "One is not a smart watch. The company, their core technology is in laser display and virtual touch technology, I still remember the first time I got such a small laser module, and I was a happy thing for all the members of all of our fig, I have to know We have been looking for a long time in the world. We have had similar products in our previous research and development, which can projected 88-inch pictures, but the volume is large, and the portability is a lot. As for whether it will be equipped with a full set of Viband technology, depending on one The function definition of the CAST product and the product status of the final market. "
It is reported that the CAST series of CASTs in the technology will be deeply excavated by the University of Carnegie Mellon, and the technology is commercialized and the application field is not excluded in the field. CAST II Based on virtual touch and laser display technology will be listed at the end of the year, and it will take the lead in providing the use interaction mode of the scene, we will continue to pay attention.
Technology is constantly, exploring is not limited
In the Internet age, the mobile phone acts as a medium in line-in virtual society and real society, in a short time, smart watch does not undertake mobile phones, or replace mobile phones, but about "next-generation mobile communication equipment" exploration Still continuing, from smart watches to the VR helmet, from wearable moving cameras to future glasses, wearable smart devices seem to have experienced the embarrassment of the big screen smartphone just once happened, but this exploration is required to encourage. After all, before the iPhone released, we didn't know what the next generation smartphone would be like. As mentioned above, use the interactive technology like Viband, Tesla Touch, Projection Touch, Soli, Direct, and provide direct Simple and comfortable interaction, then wearable smart devices will gradually change the image of "advanced toys" in people's minds, and will have more intimate interaction with consumers.
