I’m trying to detect 2 fixations one after the other which are in close proximity on the screen to each other.
I am checking for a fixation by waiting for a begin fixation event, the comparing the data fixation timestamps that come after until they reach a threshold without an end event happening. The issue is once I have the first fixation, if where the next fixation is in the same place or very close the eyex engine stays raising data events until I look away and look back, which creates and end event and the engine stats waiting for the next begin event.
Is there a way to force the eyex engine back to the state it is in before the begin fixation event, without the user having to look away and back?13/10/2016 at 15:02 #5824Grant [Tobii]Keymaster
Hi Richard @hornoo,
Unfortunately with the Tobii EyeX, fixations are determined automatically without the option to fine tune the parameters.
This kind of functionality to access raw data, adjust fixation settings, etc is only allowed within the Tobii Pro range of eye trackers which are designed for scientific research.
The Tobii EyeX is designed for interaction and gaming only and long term storage of fixation or gaze data is prohibited according the Tobii EyeX SDK licence agreement.13/10/2016 at 23:08 #5826Richard HorneParticipant
I dont want to tune the fixations, I want to force the engine to start waiting for a new fixation eg the state the fixation is in before it raises a begin event. This is just for interaction we are not storing data at all.14/10/2016 at 11:01 #5828Grant [Tobii]Keymaster
Hi Richard, okay thanks for the clarification. Apologies, but a new fixation will only be counted once a user has indeed looked away from the initial fixation area. Within the EyeX SDK there is no way to reset this behaviour.
