Eye-tracker Lets You Drag and Drop Files with a Glance
Bored of using a mouse? Soon you’ll be able to change stuff on your computer screen — and then move it directly onto your smartphone or tablet (平板电脑)一with nothing more than a glance.
A system called EyeDrop uses a head-mounted eye tracker that simultaneously records your field of view so it knows where you are looking on the screen. Gazing at an object — a photo, say — and then pressing a key, selects that object. It can then be moved from the screen to a tablet or smartphone just by glancing at the second device, as long as the two are connected wirelessly.
“The beauty of using gaze to support this is that our eyes naturally focus on content that we want to acquire, says Jayson Turner, who developed the system with colleagues at Lancaster University, UK.
Turner believes EyeDrop would be useful to transfer an interactive map or contact information from a public display to your smartphone or for sharing photos.
A button needs to be used to select the object you are looking at otherwise you end up with the “Midas touch”(点石成金)effect, whereby everything you look at gets selected by your gaze, says Turner. ‘‘Imagine if your mouse clicked on everything it pointed at,” he says.
Christian Holz, a researcher in human-computer interaction at Yahoo Labs in Sunnyvale, California, says the system is a nice take on getting round this fundamental problem of using gaze-tracking to interact. “EyeDrop solves this in a slick (灵巧的)way by combining it with input on the touch devices we carry with us most of the time anyway and using touch input as a clutching mechanism,” he says. “This now allows users to seamlessly (无缝地)interact across devices far and close in a very natural manner.”
While current eye-trackers are rather bulky, mainstream consumer devices are not too far away. Swedish firm Tobii is developing gaze-tracking technology that can be installed in laptops and tablets and is expected to be available to buy next year. And the Google Glass headset is expected to include eye-tracking in the future.
Turner says he has also looked at how content can be cut and pasted or drag-and- dropped using a mix of gaze and taps on a touchscreen. The system was presented at the Conference on Mobile and Ubiquitous Multimedia in Sweden, last week.
The word “ this” in Paragraph 6 refers to
选项
A.application of gaze-tracking in human-computer interaction.
B.combination of gaze-tracking with input on touch devices.
C.interaction between human and computer.
D.generalization of EyeDrop system.
答案
B
解析
第六段第二句明确表述了“把视觉追踪技术和便携式触摸输入设备结合起来可使用户更加自如地操作”,故答案为B。
