hi, i’m a student and a newbie in tobii, I want to make an application using gaze as interactor. my question is, is it possible to use gaze data (minimalgazedatastream’s result = x, y, time) as input to activate a button ? And I want to use filter and measure the similarity (Pearson product and euclidean distance) minimalgazedatastream’s result before activate the button to know the accuracy and precision of the gaze. English is not my mother tongue, please excuse any errors on my part.
Hi @gintaran and thanks for your query. Yes indeed! It’s very possible to use the gaze data to activate a button on your own customised application.
To get started quickly, we recommend that you download the sample application “Interaction_WPF_101” from the Core SDK Github page @ https://github.com/Tobii/CoreSDK
wherein it is demonstrated how to make a WPF component gaze aware (which of course can include a standard button) and react when gaze data is received.
That being said, I am not sure how you intend to determine accuracy and precision using this technique.. perhaps you could expand on this and your project intentions? Please be aware that any use of the Gaze Data for analysis requires the purchase of the analytical use licence for these purposes.
You can read more about this @ https://analyticaluse.tobii.com/
Also, have you already seen within the Tobii Software in the tray icon the option to “test and improve calibration”? If you select this, you will be given a graphical representation of the accuracy for your profile…perhaps this is sufficient for your needs?
