Although smart mobile devices bring a lot of new experiences to users, at least in terms of typing, the user experience of mobile devices is far less than the traditional physical keyboard, but the application of haptic feedback technology is likely to change this situation. .
The New iPad conference on March 7 left a suspense.
Before the launch of the conference, Apple began to cooperate with Senseg, a touch-sensing technology company from Finland, to take the touch screen experience of the new iPad to a whole new level. Apple not only invited Senseg to participate in the conference, but also set the slogan of the conference as "We have something you really have to see. And touch", which hinted at the appetite of the outside world.
Although the final release of "Steak" is not as presumed to implant a new generation of touch feedback technology, but perhaps in the next generation of products released next year, this technology will officially meet with you.
The release of the real touch experience "Steak" also made Senseg, an unseen startup, surface.
In 2006, Senseg was founded in Finland. The tactile feedback technology developed by it was able to accurately simulate the surface texture of textiles and was named one of the 50 best inventions of the year in 2011 by Time magazine.
Senseg's tactile feedback technology does not change the physical structure of the device's display. Its principle is to emit an electrical signal that is difficult for the user to detect, creating an oscillating electrostatic field around the skin. When the user touches the display screen, the static electricity can adjust the friction between the finger and the display screen, thereby causing the user to have a realistic texture feeling.
Coincidentally, at this year's Los Angeles International Graphics Annual Conference, a display device called REVEL developed by Disney was amazing, and its technical principle is quite similar to that of Senseg. When the user crosses the REVEL by hand, on the surface, only the hand is in contact with the smooth glass screen, but the user experiences the touch of such things as wood products, walls, pebbles, and the like.
Although this technology has not really been introduced to the market, it is enough to expect from the existing description. Think about it, since the popularity of smartphones, how long have you not been blindly texting? Although the iPhone's frenzy has subverted the mobile phone industry and brought many new experiences to users, at least in terms of typing, the current user experience of mobile devices is far less than the traditional physical keyboard. The application of Senseg and Disney's haptic feedback technology is likely to change this situation.
In fact, in 2009, Microsoft also applied for a patent on "tactile" - "light-induced shape-memory polymer display screen". Contrary to Senseg's principle, Microsoft's technology is precisely to change the physical characteristics of the touch screen so that users feel the same effect as the real scene. It is reported that Microsoft uses a polymer coating with sensitizing and memory properties. Under different wavelengths of ultraviolet light, the coating will harden or soften and return to flatness.
In June of this year, a company called Tactus turned the scene depicted in the Microsoft patent into reality, of course, in a different way. According to the prototype product displayed by Tactus, when the user needs to call the keyboard, the original smooth and smooth touch screen will be magically deformed. Each key of the keyboard will correspond to a circular protrusion, and a physical keyboard will appear in an instant. The touch screen will be restored to its original flat state. This performance is quite similar to the actual effect depicted in the Microsoft patents of the year, but Tactus's technical principles are not the same as Microsoft's.
Tactus adds a so-called "force feedback layer" to the display that is no more than 1 mm thick. The “force feedback layer†is a carefully designed small channel filled with liquid. When a physical keyboard is needed, the distribution of the liquid changes. Through different channels, the liquid accumulates in specific areas of the touch screen. The physical buttons of the blister-like hemispherical protrusions are quite amazing.
Popularization is on the way <br> Apple and Senseg are still on the move, but the old touch technology company Immersion is pushing the haptic technology to the mobile device market.
Gamers and friends are no strangers to this company. The TouchSense force feedback technology developed by it is widely used in the vibration handles of game consoles such as XBOX 360 and PS3. The handles equipped with this technology can make different vibrations in response to the movements in the game screen, such as simulating the vibration of different terrain driving in a racing game.
Founded in 1993, the company has been focusing on the development of touch-related technologies for nearly 20 years. It has accumulated more than 1,200 patents worldwide, and nearly 400 million mobile devices are using the technology developed by it. Compared with the sci-fi Tactus, the technology of this veteran manufacturer is much more pragmatic.
Mobile phone vibration is no stranger to everyone, Immersion's tactile technology is derived from the traditional mobile phone vibration. At present, the vibration function of the mobile phone mainly relies on the built-in LRA (linear resonance actuator) and ERM (rotary deflection quality micro-motor) built in the mobile phone, and they can only provide a fairly basic vibration effect. However, with the development of LRA and ERM, software programming can re-set the vibration effect to achieve rich applications, which is the advantage of Immersion.
During the GSMA Asia Mobile Communications Expo held in Shanghai in June this year, Immersion frequently contacted local manufacturers in just a few days to seek opportunities to enter the Chinese market. At present, the Immersion technology license has already included many well-known manufacturers such as Samsung, LG, Nokia, and Pantech. Among them, Samsung's previous best-selling products, Galaxy S 3 and Galaxy Note, use Immersion technology.
At the show, Immersion showed the media a number of applications using Immersion technology, such as the game's angry birds optimized by tactile feedback. The vibration effect when the user pulls the slingshot is quite different from when the projectile hits the target. Immersion currently offers three different solutions.
First, for OEMs' TouchSense solutions, TouchSense has three low-to-medium-end software solutions, TouchSense 2000, TouchSense 3000 and TouchSense 5000, supporting LRA, ERM, piezoelectric sensors and EAP drivers for use with Imagis and TI drives. .
In addition, Immersion is able to provide a tool called "Integrator" that quickly and easily integrates haptic effects into OEM-customized Android systems to automate the haptic integration process.
Immersion also provides SDKs and a range of other tools for third-party developers, with more than 100 vibration feedback effects preset, such as explosions, plucking strings, and more. Developers can add this effect to games and apps that don't have touch effects.
Dennis Sheehan, vice president of marketing at Immersion, said during the Shanghai media that Immersion's software is very cost-effective and the new cost per mobile phone will not exceed $1.
Although the cost is not a problem, the biggest challenge for Immersion is the power consumption problem. Although the current smartphones can provide a basic vibration experience, many users have chosen to turn off this feature in order to save power.
In any case, the new touch technology is subverting the user experience of smart device touch screens, of course, the most anticipated is still the next generation of iPad. In the context of the iPhone 5's lack of innovation and criticism, will Apple rely on Senseg's tactile feedback technology to make a beautiful turnaround? Everyone will wait and see.
What is 5G CPE?
Definition of 5G CPE
CPE stands for Customer Premise Equipment. The so-called front end refers to the equipment in front of the customer's terminal equipment. When we use Wi-Fi, if the distance is far, or there are more rooms, it is easy to appear signal blind spots, resulting in mobile phones or ipads or computers can not receive Wi-Fi signals. The CPE can relay the Wi-Fi signal twice to extend the coverage of Wi-Fi.
What are the benefits of CPE?
Through the following comparison table, it is not difficult to understand the technical advantages of CPE products:
* Currently, the global 5G FWA service is mainly in the Sub-6GHz band, with only the United States and Italy supporting the millimeter wave band.
* 5G CPE integrates the low cost of Wi-Fi and the large bandwidth of 5G, combining the advantages of the two to form a strong complement to traditional fiber broadband.
The relationship between 5G, FWA and CPE
It can be said that FWA (Fixed Wireless Access) will be the most down-to-earth application of 5G technology. FWA business plays a key role in enabling "connecting the unconnected." FWA is a low-cost, easy-to-deploy flexible broadband solution. Compared with wired access technology, FWA has been an ideal choice for deploying broadband in many countries and regions because it does not need to obtain rights of way, dig trenches and bury cables, and drill holes through walls. The development of 5G technology is further promoting the development of FWA.
FWA services (including 4G and 5G) have reached 100 million users. FWA is no longer a niche service; The FWA industry as a whole has been supported by numerous suppliers. Why is that? In the 5G era, 5G CPE receives 5G signals from operator base stations and then converts them into Wi-Fi signals or wired signals to allow more local devices to get online. For operators, the initial user penetration rate of 5G is low, and the investment is difficult to realize quickly; The CPE business can use the idle network to increase revenue for operators, so major operators vigorously promote the development of 5G CPE.
FWA services can be used for both home (To C) and business (To B), and customers have different requirements for CPE devices when using FWA services in different application environments, resulting in consumer grade 5G CPE and industrial grade 5G CPE (similar to home routers and industrial routers).
In 2020, the global market size of 5G CPE will reach 3 million units, and it is expected that in the next five years, the market size of 5G CPE will maintain a compound growth rate of more than 100%, reaching 120 million units in 2025, with a market value of 60 billion yuan. As an important market for 5G CPE, China's 5G CPE market size will reach 1.5 million units in 2020 and is expected to reach 80 million units in 2025, with a market value of 27 billion yuan.
The difference between 5G CPE and other devices
CPE can support a large number of mobile terminals that access the Internet at the same time, and the device can be directly inserted with a SIM card to receive mobile signals. CPE can be widely used in rural areas, cities, hospitals, units, factories, communities and other wireless network access, can save the cost of laying wired networks.
A Router is a hardware device that connects two or more networks, acts as a gateway between networks, and is the main node device of the Internet. Routers use routes to determine the forwarding of data. If it is a home router, it does not support a SIM card slot, and can only receive signals by connecting to optical fiber or cable and then convert it into WI-FI to provide a certain number (several) of terminal devices to surf the Internet.
Industrial 5G CPE is equivalent to 5G industrial routers, and the technology of the two is not very different. On the one hand, the industrial 5G CPE converts 5G network signals into WiFi signals for transmission, and on the other hand, the data received by the WiFi network is converted into 5G network signals for uploading. In addition, industrial 5G CPE generally supports routing functions.
5G CPE trends
According to a research report, after evaluating the products of some mainstream 5G CPE suppliers, many institutions believe that the development of 5G CPE products will continue in two aspects: one is to support mmWave and Sub-6 GHz at the same time; Second, the design will pay attention to humanized operation and installation. The industry development trend will accelerate the demand for 5G in the medical, education and manufacturing industries due to the epidemic, and 5G FWA will promote global 5G CPE shipments.
