    Hi, Jenny.

    I think that there is another method not using global variables.
    But it’s really helpful and I’m very grateful to both of you.

    best regards.

    For more clarification, i think i should explain more details about what i want to do.

    I have some points in 3-d coordinate, and i want to project that points to eye positions using Tobii eye tracker.

    I just want to calculate projected points coordinate.I think it’s not an analytical use.

    But for that, i need to get ‘user key input’ in real time without delay in function ‘HandleEvent’

    and i need to get eye positions and gaze point data simultaneously.

    Hi, Grant.

    I don’t understand why we cannot use gaze data for our application(like game)?

    Don’t SDK provide that?(Isn’t it “development kit” literally?)

    I just want to use gaze point data value for our application.

    For that i need to bring out the gaze point data from ‘HandleEvent’
    (or use the gaze point data in ‘HandleEvent’ function, if it’s possible to get ‘user key input’)

    Isn’t it possible?

    Thanks for your reply,,,

    I know why the delay happened.
    I’m using ‘OpenCV’ library, and i add the function like ‘waitKey’ to display the image or to get ‘key input’ in ‘HandleEvent’.
    So, delay happened. (function ‘waitKey(delaytime)’ waits for delaytime)

    But, i still need to get ‘user key input’ because i need to save or use ‘gaze data’ for my experiments.

    I have some new questions…

    1) I want to bring the ‘gaze data’ to ‘main’ function, then use the ‘gaze data’ in ‘main’ function.
    But, i don’t know how to do that. (not always need to bring data to main function, bring data when i want to)
    (i don’t know how to get out ‘gaze data, eye position data, etc’ to ‘main function’ or outside of ‘HandleEvent’ function)

    2) If i need ‘user key input’ in ‘HandleEvent’ without delay, what should i do that?
    (for example, when i press ‘b’ key, save the ‘gaze data’ for a while in .txt file)

    3) Sample code ‘MinimalGazeDataStream.c’ exit the process, when i press any key. (because of ‘_getch()’ i think)
    But i want to change that when i press a specific key(like ‘space key’ or ‘a’) then the process is terminated.
    How can i do that?

    Thanks.

    Hi Grant.
    Maybe we are using ‘Assembly Tobii EyeX Development kit’.
    ‘Tobii EyeX Controller’ and ‘Develpment kit’ are written on the box.

    Do i need a tobii pro product?
    If i get a Tobii pro product, i can access whole data through entire process?
