Mobile gaze-based screen interaction in 3D environments (D. Mardanbeigi, 2011)

Diako Mardanbeigi presents a method that enables the user to interact with any planar digital display in a 3D environment using a head-mounted eye tracker. An effective method for identifying the screens in the field of view of the user is also presented which can be applied in a general scenario in which multiple users can interact with multiple screens. Diakos PhD project at ITU Copenhagen concerns mobile gaze-based interaction.

Setscan EyeLock - Law enforcement training system

Setscan, a Canadian supplier of training equipment for law enforcement and military have partnered with Arrington Research to develop a binocular headmounted system with associated software called Eye Lock. The system aims at evaluating and optimizing officers allocation of visual attention. Looking at the right thing is obviously important as milliseconds count when guns are drawn. The eye tracking system is the same as those used for any natural-scene perception research but the market adaptation and focus to meet the needs of a specific domain is interesting.

UCSF using eye tracking to detect early stages of neurodegeneration

Sabes Lab at University of California, San Francisco are using high speed eye tracking systems to study eye movements as a tool for detecting neurodegenerative diseases. The data collected including response time, fixation accuracy and saccade velocity. These are important parameters that could identify approaching or existing neurodegenerative conditions such as Alzheimer. This area holds a great market potential and is feasible in a near future as the remote systems are coming closer to meeting the requirements of tracker speed and accuracy.

The EyeHarp: An Eye Tracking Based Musical Instrument



The main goal of the Zacharias Vamvakousis EyeHarp project is to allow people with paralysis resulting from Amyotrophic Lateral Sclerosis to play music using only their eyes. To build this, Zacharias was inspired by the EyeWriter open source initiative: "...a low-cost eye-tracking apparatus & custom software that allows graffiti writers and artists with paralysis resulting from Amyotrophic lateral sclerosis to draw using only their eyes". Zacharias spent only 50 euros to build his eye tracker using a modified version of the Sony PS3 eye camera. The application is implemented in openframeworks v0.6. 


Alternatively, the instrument can be controlled using the mouse pointer (MouseHarp version). Then the free software camera mouse can be used to control the instrument with head movements. Any technology that can take control of the mouse pointer can be used in order to control the instrument. That way the mouseHarp could be an appropriate instrument for many cases of people with physical disabilities. The mouseHarp version is completely independent from the eyeWriter project. Combining the mouseHarp source with the source of the eyeWriter project, we get the eyeHarp! A low-cost gaze controlled musical instrument! Both versions are free and open source.

The EyeHarp project is part of Zacharias master thesis in Sound And Music Computing in UPF, Barcelona. His supervisor is Rafael Ramirez.

A paper on the application has been published:

Grinbath's EyeGuide

Texas based Grinbath recently announced the EyeGuide head mounted tracker. It's main competitive advantage is the low cost $1495, academic discounts are available ($1,179). The device captures eye images using a wireless camera, running on three AAA batteries, and streams these to a computer for processing. The package includes basic software for analysis and visualization.  See the whitepaper for more information.

Proceedings from Novel Gaze-Controlled Applications 2011 online

The proceedings from the Novel Gaze-Controlled Applications 2011 conference are now available online. The conference that took place at the Blekinge Institute of Technology in Sweden during May 26-27 presented 11 talks covering a wide range of topics from gaming and gaze interaction to eye tracking solutions. Unfortunately I was unable to attend but luckily I'll have a couple of days interesting reading ahead. Kudos to Veronica Sundstedt and Charlotte Sennersten for organizing the event.
