Robots also play with cutting ropes? Intel developed Oculus robot to test device response speed by playing touch screen games

In a tiny lab at Intel's Silicon Valley headquarters, the robot named Oculus is playing cut the Rope game on smartphones. With the precise positioning of the two-finger rubber end and micrometer, it cleanly completes the touch and slide on the screen and gets a good score. This is compared with the original design of Oculus, the progress is more than stint Ah, initially just to do in the chip factory to do some of the boring work of the silicon chip, and now, in order to test whether the tactile and interactive behavior reflects the content of the screen after the joy and evil. The Oculus is analyzed by the response of the target to its touch screen. Red provides a high-speed camera to monitor, it is equipped with 300 frames per second and exceeds the HD resolution. Then use the software to analyze the video to see how the device reacts to the Oculus. For example, the brush trajectory in the drawing software and the oculus of the finger movement trajectory, the touch-screen Keyboard response to the type behavior, the robot to operate the navigation roller and jump out of the menu response. The test scores were converted to a 1-5-point rating, and the rating and cognitive psychology Experiment "what people like to manipulate the interface" to correspond. The test results of hundreds of people were divided into several levels of interactive reactions. The quiz was launched by psychologists from the Intel Interactive Experience Group, which was designed to study the relationship between machines and people. The results of the tests are significant for the Intel chip-based touch-screen device engineer. is just as important for Intel's chip designers. "We can accurately predict what the user feels is a good experience and use the data to show where it needs to be improved," said Matt Dundord, user experience Manager. "The traditional process needs to have a user experience expert to operate the touch screen machine to test, then give professional evaluation but also difficult to avoid their own subjective opinion." This makes it difficult to give the product a clear indication of where to improve. At present, Intel does not explicitly give some details on how fast the touchscreen reacts. But Eddie Ralegh, a robotics engineer who helped make Oculus, said that a good touchscreen response to a user's finger should be less than dozens of milliseconds. In the test of real users, the results show that people's perception of the quality of the screen will vary depending on how they operate. In the use of stylus, people will unconsciously increase the expectations of the screen. "Because people are very familiar with pencil pens, they are supposed to be very fast in real-life situations, with about 1 milliseconds of latency," Raleigh explains. "In any use environment, children are more responsive to screen response than adults," he said. Based on this, the experimenter will set the Oculus according to the situation, "we can simulate the initial use of the slow operation of new users, but also can simulate the enthusiasm of the rapid action of people." "Intel currently has 3 Oculus in use and the 4th is in production." They apply to any screenScreen Quiz, a small size smartphone to a large screen in one machine. Its identification camera system adjusts to the resolution of the screen. Intel has also produced semi-automatic equipment to test the acoustic systems on phones and tablets. In soundproof rooms, use a device equipped with microphones, speakers, and cameras to test the voice recognition performance and accuracy of the personal assistant app. There is also a complex array of camera imaging systems to help identify colors. Jason Huggins, co-founder and CTO of Sauce Labs, revealed that many of the mainstream mobile-phone tablet makers have robots similar to those of Oculus. "Samsung, LG, and Apple all have robots that help test them, and they are not made public to prevent competitors from knowing too much." "Dunford says Oculus is a lot more innovative than other robots because Oculus is comparing the data on the screen to learn how people use the touchscreen." Other robots focus on basic product quality testing to see if they meet the design parameters of the product. Huggins is trying to implement such a robot because it can greatly help application developers to refine their products. He also announced a robot called Tapster Open source design, Tapster can only use the ordinary stylus, this seems less than Oculus but the price is only a fraction of Oculus. Most of its components are made from 3D printers, and about 40 are sold. "If the robot is made to test the app, I expect it will be a big market," Huggins said. Software companies now outsource tests to companies like sauce Labs, who use manual tests to cover all test points. The robot test will be a good choice and he predicts it will be a trend. "We have to think about it because it's not just the keyboard and mouse that can be manipulated." There are mobile phones, tablets, Tesla's 17-inch touchscreen, and even Google Glass, Leap Motion These things that don't even need to touch. They are controlled by their eyes, so the robots of the future must also have visual ability to do so. ”
