A developed 120-fps pupillometry demo system was able to achieve a calibration accuracy of 0.003 mm and an averaged temporal pupil measurement detection accuracy of 0.0059 mm in stereo mode. We offer a selection of six state-of-the-art open-source pupil detection algorithms (Starburst, Swirski, ExCuSe, ElSe, PuRe and PuReST) to perform the pupil measurement. This work’s core outcome is an integrated cross-platform (macOS, Windows and Linux) pupillometry software called PupilEXT, featuring a user-friendly graphical interface covering the relevant requirements of professional pupil response research. Our goal was to make a professional remote pupil measurement pipeline for laboratory conditions accessible for everyone. Here, we developed an open-source pupillometry platform consisting of hardware and software competitive with high-end commercial stereo eye-tracking systems. Moreover, commercial systems rely on closed software, restricting conclusions about the used pupil-tracking algorithms. Mostly commercial solutions are used as measurement devices in pupillometry which is associated with high investments. Diameter changes in the range of 10 –2 mm are of interest, requiring reliable and characterized measurement equipment to accurately detect neurocognitive effects on the pupil. (I don’t know where to find this setting, though.The human pupil behavior has gained increased attention due to the discovery of the intrinsically photosensitive retinal ganglion cells and the afferent pupil control path’s role as a biomarker for cognitive processes. Has it anything to do with ASCII and hexadecimal? The first source says to type in ASCII, yet I believe CoolTerm reads in ASCII by default. This forum has had a question about connecting MindWave Mobile to Bluetooth, yet every participant of that thread seems to have gotten past this point of the Bluetooth connection process.ĭoes anyone know what I am doing wrong other than perhaps not retyping the command immediately after it fails the first time? This issue is extremely puzzling, as I know for sure I copied the unique identifier correctly, so there should be no issue. I have yet to see any source on the Internet explain clearly what CoolTerm expects from this command in particular. It also did not work.Įvery single format I tried has failed, yet I know certainly that I copied the unique identifier of the MindWave Mobile 100% correctly. I tried replacing the colons with commas while capitalizing. I tried replacing the colons with commas. I then capitalized while the colons were present. “AOK” was not displayed.) I tried this with capital letters. I could have tried it, though, but I have forgotten since I typed in so many commands that it is difficult to remember.)Īnother source says to type the first four digits, then a comma, then two more digits, then a comma, then the rest of the unique identifier. (Thus, it does me a disfavor to admit that I probably did not try this. Honestly, I perhaps did not do so, so now I expect everyone here to tell me to try that even when there could be another issue. This source ( Hackers in Residence - Hacking MindWave Mobile - ) says to retype the command if it fails. Since “AOK” was not seen after I typed this command but was seen for previous commands, I conclude that the command has some error. Supposedly, I am to type into CoolTerm “SR,9cb70d90ecc5”, and this should cause the terminal to respond with “AOK”. Do not worry for me in this respect I shall sacrifice sleep if I must to finish on time.ĭuring this stalling period, I would like to find out why the CoolTerm serial port terminal for Windows will not recognize the unique identifier of the MindWave Mobile EEG headset, which is certainly and exactly “9c:b7:0d:90:ec:c5” on my computer. I accidentally broke the Bluetooth module today trying to factory reset it, so will have to order a new one, thus stalling the project for up to 50% of the remaining time until the due date. I have an Arduino Pro Mini connected to a FTDI SmartBasic connected to a Bluetooth Mate Silver.
