We tried the fixation points scheme you suggested, but by doing so the center point shifted beyond the fixation window and we still did not solve the issue with the previously mentioned points. Moreover, we boosted the eye signal as much as possible but we can not increase the signal more because it saturates. As eye tracker, we are using a CHAMELEON3 CME-U3-13Y3M Camera, connected to NIMH ML thrby Anna_Bert - Questions and Answers
Hi, As we previously told you, after your suggestions, we improved the 2D calibration by putting the camera more close to our subject and boosting the eye tracker input, however there are still two positions with a 2-3 degrees shift. We noticed that when calibrating eye signal, Matlab continues to give us the warning message: "matrix is close to singular or badly scaled. results may be inacby Anna_Bert - Questions and Answers
We followed your advice and we managed to treat the lever as a joystick and to hide the joystick trace on the monitor, and everything seems to work just fine. So thank you!by Anna_Bert - Questions and Answers
Hi, We are creating "a lever task" in which we need to control both the eye and a lever. Specifically we have two blocks: during block 1 a stimulus(sample) is presented and the subject has to move the lever in one direction (forward); while during block 2, there are no stimuli presented and the subject has to move the lever in the other direction (backward). Our lever generates an analby Anna_Bert - Questions and Answers
