Create a heatmap with Tobii eye tracker 4C

[Otto MP]

Hi all, I’m totally new in eye tracking technologies, but I’m very interested to buy a Tobii 4C abd build a personal project to create a heatmap where I can show what a person is looking for a longer period of time. My first question Is: Is that possible with a 4C device? If so, my next question might be silly, mostly because I don’t know how the hardware works, but can I use it to track something that I’m looking at besides the laptop screen (like a shirt, a window, etc) or does it only track content from the laptop since where it’s being connected?

Thank you!

Hi @ottomejia24 and thanks for your query. The Tobii 4C Eye Tracker and associated usage licence are intended for interaction and gaming purposes only.

Whilst it is possible to use the 4C for research or analysis, in order to do so, one must purchase a special analytical use licence from Tobii which would entitle you to use the Correct SDK for this purpose. You can read more about this @ https://analyticaluse.tobii.com/

In terms of using the tracking on a non-screen stimulus, indeed this is possible with the Tobii Pro range of eye trackers such as the Tobii Glasses (https://www.tobiipro.com/product-listing/tobii-pro-glasses-2/) but I am afraid such a setup is not supported with the 4C.

Please do let us know if we can provide any further information.

Thanks,this is actually pretty helpful; do you have any device that can perform eye tracking without the user having to “wear it”? Lets say I put a web camera-like in front of the user and being able to do eye tracking of whatever that person is looking at? I might be talking nonsense, but that’s what I would like to play with.

Thanks!

Hi @ottomejia24, I know what you mean. Tobii Pro does offer a screen-based tracker such as the https://www.tobiipro.com/product-listing/tobii-pro-x2-30/ which can be configured for a non-screen setup such as a projector or mobile/tablet solution.

In terms of tracking an object in real world 3D, the Tobii Glasses are the only suitable solution for this.

Of course, you could theoretically calibrate the 4C on a monitor and simply place a roughly 2D object such as a book or t-shirt on top of the screen but we could not support such as setup and as I stated before, use of the tracker for such purposes would require the purchase of the analytical use licence.

Upon further research, I am ok with having the Tobii 4C connected to a laptop; I wpuld like to obtain the gaze data to analyze what a person is looking at, Is that possible with a 4C? If so, and being for just personal research, do I still need a license? If this is also true, where do I get it from?

Thanks!

Hi @ottomejia24, okay thanks for the clarification. In order to use the 4C for analysis, you would still need to apply for the special analytical use licence
