Leap Motion First Experience: instead of a mouse? Early

Leap motion early delivery, a number of foreign media have already got the equipment and started to demo. So is it really the same as the legend to subvert the human-computer interaction artifact? Be patient and look down. Leap Motion price Only 80 U.S. knives, such low-cost revolutionary peripherals do not take the path of the public is relatively rare. In appearance, Leap motion is very compact (1.27cmx3.04cmx7.62cm) and weighs 0.1 lbs (45 grams). The whole is very close to a USB disk, its silvery-white appearance is a good match for the MacBook Pro-it feels like an Apple device. With the USB 3.0 Micro-b interface on the left side of the device (the actual data transfer rate is still USB 2.0), you can connect the leap motion to the PC. A small led on the side of LEAP will display the current state. The point to note is that the difference between leap and Kinect is not just in shape. LEAP uses infrared optical capture and Kinect uses depth capture, which covers less than the latter. Leap's capture accuracy is unmatched by any of the current depth cameras: It monitors your 10 fingers with a 1/100-millimeter precision and monitors the refresh rate higher than the display. This excellent precision is not only because of the hardware, but also because of leap good matching algorithm. The setting after leap to connect to a PC is very simple-click on a bunch of "next". After that, create a airspace store account (equivalent to Leap's App Store), and then download or load some apps--leap need a matching app to use. The bad news: Leap is not as easy to install--whether it's ET, Engadget, or Theverge's correspondent, the description all points to the word "a bit frustrating (a bit frustrating)". As mentioned earlier, the evaluation criteria of leap platform look back to the software. That's why companies are taking a lot of effort to integrate with developers through additional beta releases. Currently leap's airspace store has 54 win 7 and win 8 apps, and 58 for Mac OS X 10.7 and above. There are 9 of them are unique to Windows, 14 is unique to the Mac-still 1, right? There are also 1 touchless, which are available in Windows and Macs, but with different versions. The ideal use scenario for Leap motion is that the user can sit comfortably on a chair, waving a wave or poking a finger to complete the human-computer interaction process. But from the test results of ET, we are far from this goal-the main lack of the word "comfortable". Leap can form an approximate 8 square around it.Feet in the sensing area. Given the proximity of the user to the device, the concept of 8 sq ft should be a big one. But unfortunately, the leap from the test results seems to have a much smaller sensitive area than 8 square feet--and, worse, leap will change for different app-sensitive areas. So when the user is operating on the interface, you twist your neck or lean back against the back of the chair, and your posture is readjusted. From the app point of view, most of the application is to cut the rope such a small game, there are Google Earth such applications; more specifically, leap-specific touchless, its goal is actually to turn your monitor into a virtual touch screen. However, from the current experience, Touchless also because of leap operating conditions become difficult to use, you have to carefully implement the control of each page. In the game-type app, Leap Motion has a different performance in each game. One of the Games boom ball is not a problem to operate, but the problem with leap on Dropchord is that it cannot be continuously identified-the main reason is that leap has some immediate blind spots when you move your arm. In these cases, of course, the user must maintain the gorilla-like position in front of his hands-a more tiring posture. In addition to the intermittent recognition blind spot, leap still has a problem is that it will crawl some of the original should not recognize the site. Most apps require a user to operate on a single finger, but leap often captures your knuckles and treats them as other fingers. You can't cut the other joints, of course, so the solution is to pull a bunch of joints on the screen and look around for the sensitive area of leap, which can only identify a single finger. Also, when you lean your head against your hand, leap will crawl your nose. These conditions are also different between app and app. Finally leap has some small problems, such as the adjustment of the function of the operation is inconvenient, the operation of the hands will block the line of sight and so on. In a sense, if you have a leap in the present moment, you have to tell yourself that it is the potential of your brother. Although it offers a new concept of human-computer interaction, their convenience is vastly different than the mouse or touch screen. If future leap and app developers have not solved these problems, you'll have to do it with your mouse.
