Nikki Posted March 10, 2020 Share Posted March 10, 2020 Hello, I want to get the expression data, but it doesn't work. At present, I only test Left eye_wide and find that result2 = -2 (NOT_INITIAL), so I initialize the ANIPAL_TYPE_EYE_V2. Although error = 0, the value of result2 is always be -2. May I ask what steps have I missed? Also, what does the value of Left eye wide = -2147483648 mean? I think I didn't get the eye wide of my left eye. Thank you. @Daniel_Y @Corvus Link to comment Share on other sites More sharing options...
Hank_Li Posted March 13, 2020 Share Posted March 13, 2020 Hi Nikki: If you want to initial Eye V2 engine: 1. Please do not modify any header file we provide. E.g. in SRanipal_Eye.h, the following line should be: const int ANIPAL_TYPE_EYE_V2 = 2; 2. You need a separate flag to check if eye v2 is enabled, e.g., int error = ViveSR::anipal::Initial(ViveSR::anipal::Eye::ANIPAL_TYPE_EYE_V2, NULL); if (error == ViveSR::Error::WORK) { EnableEyeV2 = true; } Then in the function void streaming(), you need separate code to handle eye v2 data, e.g., if (EnableEyeV2) { int result = ViveSR::anipal::Eye::GetEyeData_v2(&eye_data_v2); if (result == ViveSR::Error::WORK) { float *gaze = eye_data_v2.verbose_data.left.gaze_direction_normalized.elem_; printf("[Eye v2] Wide: %.2f %.2f \n", eye_data_v2.expression_data.left.eye_wide, eye_data_v2.expression_data.right.eye_wide); } } 1 Link to comment Share on other sites More sharing options...
