The development of science and technology is such a surprise that at CESAsia 2017, the scene does not see the slightest cooling of the VR market. A group of countries VR has introduced new VR products in succession. In this exhibition, Big Bang exhibited two models. Previously released new products are the Da Peng E3 VR helmet and Da Peng M2 Pro VR one. In addition, Antvision also exhibited a VR version of the Optimus VR Transformer, a VR motion camera that simulates the human eye's visual range and 3D stereoscopic effect, as well as ants as a small lemon, ants as Vega, and ants as a VR. Eyewear Energy Edition and many other types of VR glasses. Since two years ago, VR glasses have become regular visitors to various types of technology exhibitions. The popularity of booths with VR content experience is not too bad. During CES Asia 2017, HTC, Samsung, Pico and other vendors all have their own VR products.
The company called WeAIVR's "Smart Avon" VR product has attracted a hot spot for college entrance examinations at CES Asia 2017. The product introduction shows that this VR eyewear can significantly improve students' exam status. The booth site also used a large screen to play VR animations and low-grade version of Zhao Zhongxiang's reading of heart chicken soup. Many parents also consulted on the spot.
According to its official website, this product “decodes the passwords of human mind cognitive laws revealed by brain sciences into artificial intelligence, simulates senior psychological counselors and mentors (Master), and conducts dialogue and counseling with users. Systematic reshaping of the brain produces a customized “DB memory†that allows its mental efficiency to rapidly escalate. After users have upgraded their minds, they can work in four areas of their lives (physical and emotional, wealth, and (Interpersonal relations, mental awakening), to open a new life of wisdom that is light, rich, happy, and awakening.†It is quite fantasy.
Another thing that caught our attention was this "ultimate desire of wireless VR players." In fact, with the increasing popularity of VR devices, the “dumpster†behind VR helmets is also becoming a big problem. More and more companies are beginning to realize that the problems caused by this connection line are not only ugly, but also certain. To the extent it will make the player's experience worse. In many experience activities, there will even be dedicated staff who help the experience person pull the cable to ensure that there will be no security problems - although companies think of the way VR backpack can save the country, but that means It is too expensive. Therefore, wireless VR is a problem that many large companies are trying to overcome. Take HTC Vive as an example. When this device is running, the cable will transmit 15 to 20 GB of data per second. To achieve such a large data transmission wirelessly From the current technology, it is still very difficult.
However, according to the reporter's live experience, this "TPCAST ​​VIVE Wireless Kit" does allow VR glasses to do wireless display, but they chose another technology - wireless HDMI transmission, that is, through a transmitter installed on the PC and installed The wireless transmission of data on the receiving end of the helmet is actually not a new technology. At the 2014 CES, there was a wireless HDMI receiving device named “AIRTAME†exhibited, and it also received the year’s CES Best Startup Company. As an HTC Vive accessory, TPCAST ​​uses this technology in VR glasses.
Of course, HDMI wireless transmission also has a corresponding distance limit. According to TPCAST ​​staff, the use of this wireless kit is limited to 25 square meters, and the transmitter must be placed on top of the user's head (this means that Out of a line, TPCAST ​​equipped the VR helmet with two batteries of different specifications to replace the power cord, and the battery life is about 2-5 hours. The entire kit is priced at 1999 yuan, which is similar to the price of an ordinary wireless HDMI transmitter, but it is not cheap. From a certain point of view, such products may be more suitable for VR experience halls. For ordinary players, setting up a complete set of accessories is not an easy task.
Coincidentally, a company that is engaged in HDMI wireless transmission technology is also on the show. Their products can achieve data transmission of up to 100 meters. Customers of this product are outdoor advertising and meeting organizers.
This product, called NOLO, is the main product that allows the plastic box to change to the HTC Vive. The entire product contains two game controllers that resemble PS Move, a base station, and a VR marker. According to reports, NOLO has adopted a space positioning technology called “PolarTraqâ€, which uses acoustic and optoelectronic hybrid positioning to locate helmets and handles. In simple terms, NOLO is equivalent to the gyro sensor and infrared optical positioning module in the Vive helmet out to form a helmet locator, and then made a pair of interactive handles, and then to the Steam VR in the PC through wired or wireless screen shots. The content of the game goes to the mobile phone screen, and the price of this product is only RMB 800 yuan, and the threshold is quite low.
However, NOLO also has some drawbacks - such as positioning delay and accuracy, the 20ms delay determines its screen refresh rate is only 60Hz, while the accuracy of 2mm is also very difficult to achieve in practical applications, such as some shooting games. At the same time, NOLO's initialization steps are extremely complex, which is enough to keep many light users out of the door.
