AND YOU KNOW THERE MAY BE TIMES WHEN YOU WANNA TREAT THAT AS ONE THING RIGHT OH RIGHT OKAY SO BUT IN THAT CASE RIGHT UH-HUH IN THAT CASE THEN UM THESE TIERS ARE ALREADY LIKE BLINK CORRECTED AND THEN YOU WOULDN'T HAVE BLINKS AS PART OF THIS YOU'D WANT BLINKS AS A SEPARATE TIER IF YOU'RE GONNA HAVE IT IN YEAH YEAH SO THE KEY THING IS HE HERE IS MUTUALLY EXCLUSIVE AND EXHAUSTIVE AND UM THE SECOND KEY THING IS UM IT BETTER BE REALLY CLEAR TO THE PEOPLE WHO ARE DEALING WITH THESE CODES UM UH W YEAH WHETHER ANY MONKEY BUSINESS HAS BEEN DONE AROUND THE BLINKS TO CORRECT FOR THAT UM 'CAUSE YOU KNOW IT WOULDN'T NECESSARILY BE OBVIOUS LOOKING AT THAT SET OF CODES THAT NO NOT CERTAINLY L NOT LOOKING AT CODES NO UH YEAH I SUPPOSE IF YOU KNOW ABOUT EYE TRACKERS THEN YOU'LL JUST KNOW BUT OKAY SO SO THAT MEAN YOU NEED THE BLINK CORRECTIONS PART OF THE ANALYSIS THEN UM IT I THINK YOU'RE JUST SAYING IT COMES OUT OF THE EYE TRACKER ALREADY RIGHT THEY'RE ALREADY BLINK CORRECTED THEN IT'S UH I IT IS AT TH HMM AT WHAT STAGE THE SOFTWARE THAT I'VE USED UH P POOLS UH THE BLINKS SO WILL ADD IT ON I'M NOT SURE WHAT THE DEFAULT YES YEAH SO I'M NOT SU I CERTAINLY IT'S LISTED AS A SEPARATE EVENT IN THE STREAM BLINKS ARE A TAG UH FROM THE E. D. F. AND AND THAT SORT OF THING IT'S REGISTERED AS A A DETECTION BUT IT MIGHT WORTH MAKING MAKING A CR PART OF THE REQUIREMENT FOR THE G. D. F. STUFF SO TO REMIND ME SO TO TO JUST ADD THAT ANALYSIS TO YEAH TO TO IT SO IT'S I MEAN IT'S EASY ENOUGH TO DO JUST CHE JUST CHECKING THE TIMES TH TIMES OF THE EVENTS SO BASICALLY THE TIME FROM WHEN SOMEBODY STARTS LOOKING AT AN OBJECT UNTIL THEY LEAVE IT AND SO IF THEY BLINKED A LOT WITHIN THAT THEY'RE STILL LOOKING AT THAT OBJECT SO IT'S JUST THE TIME IN TO THE TIME OUT RIGHT OKAY OKAY MM-HMM YEP WHETHER HE NEEDS TO REDO THE SAME ANALYSIS BECAUSE SOMETHING ABOUT THE DATA PATH CUTS OFF THAT ANALYSIS FOR THE EYE TRACKER OR WHETHER WE EVEN LIKE IT RIGHT AND WANNA DO IT SOME DIFFERENT WAY YEAH YEAH 'CAUSE I THINK THE ASCII FORMAT AS IT STANDS DOES CONTAIN BLINK INFORMATION UM 'CAUSE UH D D I'M SURE I'M SURE THAT'S APPEARED IN THE IN THE DOCUMENTATION I'VE READ THROUGH YEAH BUT IT COULD BE THESE THINGS ARE CORRECTED FOR BLINKS IN THIS WAY PLUS THERE'S BLINK INFORMATION SO YOU KNOW IT IT TREATS IT AS A FIXATION AROUND BLINKS AND IT ALSO JUST HAPPENS TO TELL YOU WHERE THE BLINKS ARE 'CAUSE AS THEY WERE SAYING THEY LIKE TO USE BLINK RATE AS MEASURES OF COGNITIVE DIFFICULTY OR SOMETHING SO RIGHT OKAY OKAY UM YEAH SO MIGHT MIGHT WORTH US US HAVING A LOOK AT THAT AND JUST JUST SEEING WHAT DAT IS WHAT DATA IS ALREADY IN THE ASCII FORMAT AND WHETHER YOU WANT ME TO DO ANY CORRECTION AS PART OF THE ANALYSIS UM 'CAUSE I'VE GOTTA DO THE ANALYSIS FOR THE FIXATIONS ON PARTS AND THINGS ANYWAY SO YEAH I D I I I DIDN'T THINK CHECK FOR BLINKS DURING THAT ISN'T GONNA BE A SHOULDN'T BE A BIG PROBLEM IT SHOULD JUST BE A MATTER OF TREATING A B ADDING ON THE BLINK TO THE LAST FIXATION OR SOMETHING ANYWAY YEP UM SO WE'LL BE WHY IS THAT IS THAT THE RIGHT THING TO DO ANALYTICALLY UH WELL UH THE THE REAL REASON IS UM AS LONG AS THEY'VE BEEN BLINKING EVEN IF THEY THEN OPEN THEIR EYES SOMEWHERE ELSE THAT'S WHEN THEY START ABSORBING THE NEW INFORMATION IT'S BASICALLY LIKE A JUST A LONG SACCADE MM IT YOU KIND OF HAVE VISUAL SUPPRESSION WHEN YOU MOVE AND IT'S THE SAME WHEN YOU'RE BLINKING YOU'RE NOT TAKING ANYTHING IN SO WELL BUT DOES UM THE DURATION OF FIXATIONS COUNT FOR ANYTHING 'CAUSE IT IF YOU'RE JUST ADDING THE LENGTH OF THE BLINK TO THE FIXATION YOU'RE NOT TREATING IT AS A SACCADE UH IT IT'S YEAH THAT YES UM THAT'S FOR THE SORT OF GAZE TIME MEASURE UH IT'S NOT ACTUALLY THE FIXATIONS ARE STILL UM INDEPENDENT SO THE THEY W FIXATION DURATION ISN'T DOESN'T INCLUDE THE BLINK IN THE ASCII A OUTPUT IT'S ONLY WHEN WE START LOOKING AT SORT OF THE TOTAL GAZE THAT UM THE TOTAL AMOUNT OF TIME SPENT LOOKING AT ONE PARTICULAR OBJECT WHICH INCLUDES ALL THESE SORT OF MULTIPLE FIXATIONS AND ANY BLINKS AND THAT SORT OF THING IS IT IT'S A A SORT OF COMPOSITE UH VIEWING TIME RIGHT MM-HMM SO MORE COMPLICATED THAN I THOUGHT I'D FORGOTTEN ABOUT THE MULTIPLE FIXATIONS ON AN OBJECT YEAH OKAY AND SO ARE YOU LOOKING FOR A FINAL THING THAT JUST SORT SAYS BETWEEN THIS TIME AND THIS TIME YOU'RE LOOKING AT THIS OBJECT BETWEEN THIS TIME THIS TIME YOU'RE NOT LOOKING ANYTHING AND ALTHOUGH WE'LL ALSO STILL NEED A COUNT OF THE FIXATIONS JUST SO WE CAN HAVE YOU YOU'VE GOT MEASURE FIXATION DURATION AGAIN JUST TO S SEE IF THOSE THEY SPEND LONGER JUST F AMOUNT OF MORE STABLE MOVE UH EYE FIXATION OR NOT UH MM-HMM YEP TO YE YEAH MM-HMM VIEWING TIMES WELL IT'S NOT OKAY I MEAN THIS IS KINDA WHAT WE WERE TALKING ABOUT BEFORE THIS CONFUSION ABOUT WHAT'S IN THE G. D. F. I MEAN YOU MIGHT SEE IT AS THE INITIAL G. D. F. IS JUST WHATEVER STRAIGHT FORWARDLY TRANSLATES WITHOUT YOU KNOW WITHOUT TRANSFORMS WITH JUST THE DATA FORMAT CHANGING FROM THE ASCII AND THEN THERE'S A BUNCH OF OTHER THINGS THAT GET ADDED THAT YOU MIGHT STILL WANT TO BE IN UM AUGMENTED G. D. F. FORMAT YOU KNOW LIKE THIS BLINK AND THE GAZE AND WHATEVER ELSE AND THEN YOU TRANSLATE TO N. X. T. SO YOU MIGHT STILL WANNA HAVE EVERYTHING IN THIS ONE G. D. F. FILE FORMAT THAT REPRESENTS EVERYTHING AND THEN THE N. X. T. THING IS JUST A SPLITTER IT'S NOT DOING ANY FANCY ANALYSIS SO I SEE THIS AS YOU KNOW A BUNCH OF LITTLE ROUTINES THAT TAKE THE THE G. D. F. WITHOUT THIS INFORMATION IN IT AND ADD NEW INFORMATION INTO TH SUB SCRIPT VERSIONS OF THE G. D. F. FILE THAT CONTAINS THESE POST PROCESS ANALYSES WELL THAT'S PARTLY WHY I BROUGHT THIS UP NOW IS IT I'M NOT SURE WHAT POINT DOWN THE DATA PATH THINGS SORT OF HAPPEN BUT THAT'S WHAT I WANT OUT IN THE END RIGHT SO SO SO W WILL YOU ACTUALLY BE DOING MUCH OF THE G. D. F. OR IS ARE YOU EXPECTING DO MOST THE ANALYSIS ON OUT OF THE N. X. T. STUFF THEN SO WHE WHEN YOU UH WHEN YOU ACTUALLY GENERATE YOUR RESULTS MM-HMM UM WELL THE N. X. T. STUFF WILL HAVE THE MORE COMPLETE PICTURE 'CAUSE IT WILL INCLUDE COMBINE ALL THE LINGUISTIC STUFF WITH ALL THE MOVEMENTS AND THE ACTIONS
