Startup Tarsier promises a touchscreen floating in the air

Tarsier will show off its emerging user-interface technology at Demo Fall

While consumers go crazy for touchscreens on their smartphones and tablets, Minnesota startup Tarsier is working on what it calls the interface for the next 30 years: a touchscreen you don't have to touch.

Tarsier's MoveEye technology lets users reach out and manipulate icons, windows or images on a screen as if they're floating in the air, according to co-founder Shafa Wala. The company is looking toward TVs as a natural place to implement MoveEye, because users normally look at TVs from several feet away. The company will demonstrate some of the MoveEye technology at the Demo Fall conference this week in Santa Clara, California.

Despite years of promises of interactive TV, the systems that have hit the market, such as Google TV and Microsoft's earlier WebTV, have never gained much traction.

"Today, we don't really have a way to interact with our TVs from a distance," Wala said. "The remote control, the mouse, and the keyboard are really not the ideal input devices for interacting with TVs."

In place of those familiar PC tools, MoveEye uses a special pair of glasses, a "media box" to run the interface, and software. The glasses have a built-in stereoscopic pair of cameras pointed at the screen, sensors to detect the viewer's eye movements, and Wi-Fi to talk to the media box. Together, these give the illusion of viewing and touching the interface in thin air.

"You just point at what you want to interact with, or you just grab something that's projecting out of the screen," Wala said.

The first version of MoveEye will be two-dimensional, with the user manipulating objects on a plane suspended in space. Later, Tarsier will add 3D capability so users can feel as if they're reaching into an interface that has more than one layer.

Using gestures to control something on a screen is not new. Both Nintendo's Wii and Microsoft's Kinect let users play games and carry out other tasks with movements and gestures. But MoveEye can better read hand gestures as well as where those gestures are directed, Wala said. That precision is necessary for the full range of actions on a computer, such as grabbing a small object, he said.

MoveEye achieves this by viewing the screen from the user's perspective. While the Wii system follows a controller in the user's hand and Kinect faces the user and watches body movements, MoveEye captures the user's own perspective through the stereoscopic camera in its glasses. That, and the eye-tracking sensors, help to tell the system precisely where each element on the screen appears from the user's perspective, Wala said. Algorithms and software developed by Tarsier do the rest.

Though games on big-screen TVs are one obvious use for MoveEye, Tarsier has higher ambitions as well. A 3D MoveEye interface could be used for military applications such as combat simulations and controlling bomb-defusing robots, Wala said. In medicine, it could allow doctors to virtually reach inside 3D MRI scans, he said.

At Demo, Tarsier will show MoveEye working with a wired version of the glasses and controlling a customized OS based on the Boxee freeware platform. But for its eventual product, the company may use a derivative of Android and allow selected Android apps and games to work with MoveEye, Wala said. Whatever platform it uses, Tarsier believes it can offer interface innovations that make computing easier than ever.

Wala, who studied mechanical engineering and computer science at North Dakota State University and the University of Minnesota, founded Tarsier in 2010 with Axel Chevaillier, whose background is in aeronautical engineering. They brought their ideas to professor Nikolaos Papanikolopoulos of the University of Minnesota, who is helping with the project.

The company has a fairly detailed roadmap for commercializing MoveEye. It tentatively plans to put the 2D system on the market in November 2014 for about US$300. The 3D system would come out the following year.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
