There are many types of sensors that the human-machine interface may use
The sensor can detect a wide range of fields, according to the US Business Intelligence Research Institute Global Industry Analysts, Inc (GIA) study pointed out that there are about 10 or more, for example, chemical (Chemical & Gas & Biosensor) detection The representative techniques used are far infrared rays, thermal conductivity, ionization, etc., for gas or oxygen detection. Pressure detection, the principle of MEMS, vacuum, blood pressure, optics, resistance, etc., typical uses are tire pressure detection, resistive touch panel and so on. Flow detection uses principles such as Coriolis force, eddy current, ultrasonic wave, electromagnetism, and capacitance electric field. A representative application is a projected capacitive touch panel.
Others include Proximity & Displacement sensing, Image sensing, Position sensing, Level sensing, Temperature detection, Force & Load detection, etc. Wait. For details, please refer to the attached table.
In the past, most of these sensors needed to continuously detect targets or contact targets in order to obtain information on the target. However, such situations would cause wear, interference, or require greater offensive losses to provide operations. Fortunately, with the technology Progressively, many contact sensors have been replaced by non-contact sensors, and they have also overcome the aforementioned problems and even improved the accuracy and stability.
With the advancing of technologies such as semiconductor processing, miniaturization has become an irreversible trend. Sensors are also receiving considerable help from this trend. For example, the development of micro-electro-mechanical systems has made Microtek microphones, 3D accelerometers, RF components, and cameras stable. Devices and GPS gyroscopes and other consumer electronic products, of course, also brought about a considerable human-machine interface revolution. Overall, in addition to the aforementioned MEMS sensor system, according to the GIA's research, image sensors, biosensors, and motion sensors are the most important development directions, and the resulting product families are also quite numerous.
Sensor technology affects human-machine interface development
Because the importance of the sensing system in human-machine interface design is greatly enhanced, the technology of the sensor itself often becomes the key to the success or failure of the human-machine interface. Obviously, when the manufacturer designs the product, the human-machine interface technology has become the core key. Recently, the threshold for projected capacitive technology has been very high. It is mainly due to the fact that the screen has a lot of processes in terms of process and fit. For example, what kind of fit mode can achieve the best touch effect, anti-interference and ITO coating technology? The patents or intellectual property rights have caused manufacturers to suffer. The end result is that the yield is not easily pulled up and the end product is affected.
And this yield problem is not overnight. Since the projected capacitive technology has become the main technology supporting multi-touch, it has been hacking with this issue, which explains why everyone is optimistic about multi-touch technology, even on the iPhone. After the big sale, it is predicted that multi-touch will become the mainstream human-machine interface of mobile phones, but the multi-touch market penetration rate is still slowly moving forward so far.
Of course, multi-touch is not a single technology. Perhaps some technology suddenly emerged as a replacement for projected capacitors and became the mainstream of multi-touch. This also reflects the design of manufacturers and must be at the front of the development of sensors to avoid the maturity of technology. The corresponding human-machine interface technology is too late to be presented. Although this kind of R&D concept is very common in other technologies, for example, the development of OCR and BCR technologies, when a 300,000-pixel lens appears on the market, many manufacturers believe that Not feasible, but some manufacturers are already studying the effect of identification.
After researching, the manufacturer did find that 300,000 pixels could not achieve perfect results. It seems that it took painstaking efforts to reach a conclusion similar to that of a non-research and development company. However, the fact is that the lens of 1 million pixels has developed without delay. To reach the minimum threshold for identification, vendors that have studied technology in the 300,000-pixel era are immediately ahead of the market in launching real products. Human-machine interface R & D is also the same reason, when the hardware has not been positioned, it should be insight into the development trend, the development of human-machine interface technology.
For example, with touch control as an example, as touch products pop up like mushrooms, if domestic manufacturers want to follow the trend of this stock and go even before the hardware front-end design man-machine interface, the necessary mentality is: Research and think about trends in consumer product touch design. 2. Simulate future innovative touch application models and situations and explore the development direction of touch technology. 3. With different application scenarios, how product design meets consumer demand satisfaction and the development of touch technology.
Difference between sensing system and human-machine interface product
Exploring the man-machine interface, the great merits of the sensor interface behind it must not be ignored. However, due to the high difficulty of human-machine interface design, a difficult-to-market sensing mechanism has been added to this difficult task. The possibility of failure is even higher, so most manufacturers of R&D HMIs follow the market's successful technologies. Of course, after a sensor is adopted and carried forward, follow-up is a relatively simple task, but If you have a comprehensive understanding of the sensor, you may find that a sensor is suitable for designing a human-machine interface for a product and become a pioneer in the market.
