Eye Tracking Ronaldo and Combining Eye Tracking With Motion Capture September 23, 2011

It’s been a pretty hectic couple of weeks with a lot of interest in the Dikablis eye tracker after the Ronaldo footage was shown across the world… I finally got around to posting the footage on YouTube for those that didn’t see it go to http://www.youtube.com/user/AcuityETS#p/a/u/0/2NcUkvIX6no and check it out if you haven’t already.

But the TV show didn’t allow us to demonstrate the full capabilities of the Dikablis system, which is designed not only for eye tracking but also integration to other software platforms, research tools and custom interfaces. Not only does the Dikablis allow fully wireless transmission and live viewing of data up to 5km away (designed from inception for testing vehicles and ergonomics during real world scenarios) but we can also synchronise the data stream to any number of input devices. The SimLab driving simulator takes things a step further, with a choice of screen sizes and types you can create VR worlds and eye track drivers as they navigate, drive and interact with the vehicle. On top of this every key switch, button press and acceleration is logged, marked and tied together allowing you to accurately plot every aspect of the users behaviour.

For other types of experiment, such as gait monitoring, sports studies and environmental testing we can look at the D-Control interface. This allows us to add 4 additional video streams to the eye tracking data, so this could be different views of the participants, different elements the user will interact with or perhaps different views of a cricketers approach to bowl?

But we aren’t finished there…. we can also utilise the Dikablis system with the Vicon motion capture system, as seen tracking Ronaldo in the TV show and as seen in this demonstration video here : http://www.youtube.com/watch?v=tqVynnEXpY8 … so as well as having multiple views of the participant filmed by traditional cameras, we can also monitor every aspect of their body motion, limb movement and add accurate eye gaze as well. The possibilities for sports science and medical research are endless, and also what about for CGI and standard motion capture where eye gaze has been “guesstimated” in the past – we can now say with 100% certainty where they were gazing as they ran, walked, tackled and interacted.

The Dikablis has a very open API which can stream data live, so the options don’t end there either – you can integrate the system into your own systems, your own code and your own research.

Hello,
Is there no possibility to use Tobii glasses with Vicon instead of Dikablis?
Thank you.

Jon Ward - October 7, 2011

Hi Perry, I am afraid not – we tried it in three systems and the reflections from the cameras into the lens of the glasses meant no data was captured, the Dikablis allows us to control the thresholding of the camera image and pupil detection as well as the intensity of the IR so we can easily compensate for the IR of the Vicon. Also the Dikablis allows for live streaming of the data wirelessly by TCP/IP so it is fed real time into the Vicon system giving instant access to gaze and motion data.

Does Dikablis allow live streaming of video (Scene camera + eye camera) to custom applications for analysis (i.e, outside its DLAB software) ?

Hi Deepak,

Yes it does, you can poll the gaze data live on most if not all versions, and on some you can also query live AOI and marker co-ordinates.

Best, Scott.
