How the "long" rotation data is generated

Video B1

Data format description

Every "datafieldlong" and "datafieldlongfinal" data point in the raw data consists of two integers separated by a colon, like so:

106:963

Here, the first value represents the position of the eyes, from 1 to 200. And the second integer represents the time in milliseconds since the last movement of the dial, or since the moment the page was first shown:

dial_position : interval

Each data of these sets is itself separated by a comma, so after some dial rotation you end up with the following type of data in "datafieldlong" and "datafieldlongfinal":

158:9043,157:93,156:28,155:50,154:36,153:45,152:24,151:87,150:74,150:18,149:17,148:70,147:63,146:85,146:97,
145:51,144:92,144:41,143:32,142:134,142:59,141:190,140:100,139:60,139:32,138:46,137:46,137:33,136:61,135:57,
135:51,135:15,134:306,134:101,134:2086,134:588,139:1699,121:4,121:16,120:17,120:132,120:22,119:100,119:64,
121:288,122:100,122:15,123:17,124:28,124:206,125:99,125:28,126:50,126:601, ...

I therefor also parsed the data to obtain the following two files:

Here, the "datafieldlong" and "datafieldlongfinal" final data has been parsed for you. To be specific:

In other words, in these files the rotation points are represented by:

face_position : time_since_start
