Okay, stare at the icon. Want to scroll through an article? The technology got a lot of buzz this March when Samsung demonstrated finger- free scrolling and video control on its flagship phone, the Galaxy S4, during the product’s launch in New York City. The same week, LG Electronics announced it would include similar capabilities in its newest smartphone, the Optimus G Pro. The Galaxy S4, for instance, knows when to start or stop a video simply by discerning the presence of a user’s face through its front- facing camera.
And it scrolls text by sensing the tilts of the user’s wrist. Last month, it shared its tool kit with a select group of app developers, including game and e- book designers.

Umoove says it expects to release a commercial version of the kit for Apple’s i. OS and Google’s Android later this year. But these systems often require bulky external hardware and complex algorithms that demand ample processing power. So there are huge challenges when trying to adapt the technology for mobile devices. His company’s software solves this problem, he says, by pulling data from a smartphone’s various sensors, including its gyroscope, accelerometer, and compass. The system then combines the results with image data to filter out unwanted information.
Eye tracking involves measuring either where the eye is focused or the motion of the eye as an individual views a web page. Purpose of Eye tracking. When your site visitors are connected to eye tracking software, you will be. Eye tracking software for the analysis and visualization of data from Tobii Pro screen-based eye trackers. Supports the entire research process.

Updated March 30, 2011 Free and Low Cost Head Tracking Software (note head trackers can usually track any body part and more so if you put reflective tape, shiny nail polish or an LED on that body part) Note and. Face and eye tracking, software only technology, for mobile devices. Utilized for diagnosing, tracking and improving brain activity.
Three years ago, when Umoove began pursuing mobile eye tracking, its engineers thought they could borrow many of the algorithms used in PC- based systems. They ran their first program on a Nokia smartphone, Kempinski says, because it was one of the only models with a front- facing camera. It then models how those features shift between frames. To save processing power, Umoove’s software follows a different set of rules. For instance, it uses information extracted from previous frames, such as the angle of the user’s head or the acceleration of a blink, to predict where to look for facial targets in the next frame. This anticipation minimizes the amount of computation needed to scan each image. When run on a Galaxy S III, Umoove’s system uses less than 2 percent of the phone’s CPU power, Kempinski says.
The Swedish company is commercializing a consumer- grade eye tracker that would plug into a computer’s USB port. The candy- bar- size device projects infrared light and follows a user’s gaze by capturing the eyes’ reflections with a pair of cameras. The technology is already used in some cars to warn drivers when they are dozing off. It could also enable chefs to browse recipes while cooking and inform authors where readers lose interest in a text. Even simple tasks such as reading or browsing “will be more natural and more convenient,” says Robert Jacob, an expert on computer interfaces at Tufts University, in Medford, Mass.
Your phone could collect data on your eye movements, such as which Google results you skimmed, which advertisements you lingered at, and whether your pupils dilated when you read about certain subjects. That information could easily pass into the hands of advertisers or law enforcers. While you are intently watching your device, Villasenor says, “your device, perhaps unbeknownst to you, could be watching you.”.
