  1. Hi @Corvus, I am trying to understand the meaning and proper range of some of the basic variables. in the folder is called 'Document_Unity" You mentioned, there is some information but not the whole range I can get and not the meaning of any value. For example: validata_bit_mask EyeLine += eyeData.verbose_data.left.eye_data_validata_bit_mask.ToString() + ","; What is the possible range of this variable? What does the value = 31 mean? I tried to check it out in an empty scene, with one eye open and one eye closed. When I exported data to CSV file I got the value = 24 in the close eye (orange arrow) As you can see in the attached files and -1 in the diameter size variable. How does it make sense that I still get information about the location of x ,y with one eye completely closed? (blue arrow) Waiting for an answer from you, hope it arrives soon because I can not progress in my work until I solve it. thank you for your help. Tchiya
  2. @CorvusOk, I was able to get to the file you were talking about. But I still lack information on some variables. For example: validata_bit_mask EyeLine += eyeData.verbose_data.left.eye_data_validata_bit_mask.ToString() + ","; What is the possible range of this variable? What does the value = 31 mean? I tried to check it out in an empty scene, both with full eye closing and full opening. When I exported data to CSV file I got the value = 31 in both cases. As you can see in the attached table. How does it make sense that I still get information about the size of the pupil and its location with eyes completely closed? thank you for your help. Tchiya
  3. @Corvus I'm sorry, Still can't get to this file. Can you please send it to me via email? birbira98@gmail.com
  4. and one more thing, how could I transform the pupil_position_in_sensor_area (or any other parameter) into the angle between the eye and the head (or lens) in degrees?
  5. Thanks for your response, I have a few more questions: 1. The Eye Tracking SDK documentation is included with the SDK download - can you give an exact location? I could not find them in the folder. (This is an empty folder =C: \ Users \ tchiyab.PC-4D17510A \ Downloads \ Do Not Delete - Installations \ SRanipal_SDK_1.1.0.1.zip \ SRanipal_SDK_1.1.0.1 \ 02_Unity \ Document \ Eye \ html \ search) 2. I have seen that competing devices report about " Access to eye position data with 3.0 msec delay". What is the daily in the case of SRanipal SDK? 3. The pupil - I know what it looks like and it is clear to me that it is not size 0 at any moment 😃 This is just an example of something I do not understand about RAW DATA values. I expect that when there is a blink the Eye Tracking will "lose" the tracking of the pupil and report NAN or 0. I saw in me that there are consecutive samples with numbers between 2-5 so I asked if the information I get goes through some MASK that fills such holes or is it really RAW DATA? Thank you for your patience Tchiya
  6. It's so nice to get such a quick and detailed answer, Thanks Kapara. Just one more little question for now, It seems I have no blinks in my DATA. In the variable pupil_diameter_mm for example, there is no number smaller than 0.2. I expected to see at least part of it =NAN or 0. Could it be that the numbers are slipping? Could there be another function that run before I get the data ?
  7. Hello, I have some questions, I would be really glad if you could help me : 1. I'm doing an experiment using HTC PRO EYE and Unity and I am looking for a "glossary of term" that will help me understand the meaning of each variable, and the scale of possible values. Can you refer me to a relevant link? (For example for variables: Pupil Position, Pupil Diameter, validation) 2. I am looking for a variable that will return information about the confidence level of the pupil recognition. I thought that - .eye_data_validata_bit_mask Will help me, but it gives me a constant result of = 31. Can you help me understand this better - I have a problem identifying the variable or saving the data? 3. Is there a way to display in Unity real time information about eye movements (E.g. ray, Heatmaps) without it being displayed to the player? but only on the main computer? Thanks, Tchiya
