2015-09-18 | Testing the platform

Captured data from one hour commute from DTU to home

André: Reliable data.

Conclusion: Platform works

2015-10-21 | Lego Test

Building lego truck, timed. Lessons learned: Have a repeatable test instead, so all data can be compared with each other.

Patrick: At the seven minute mark he looks at the timer on camera. Suddenly he feels pressured and HRV increases

André: No useful HRV data. For future reference, let it run for a minute before and after the test

Mikkel: High HRV in the start. Described first part as harder. Lower on second part. Increase when he looked at timer for the second time (time higher than current record)

Conclusion: Rise in HRV everytime the test person looks at the time. Need longer baseline time before and after the test. Need repeatable test.

2015-11-04 | Trailers test

Video with 3 clips: Heights, "useless" facts and horror movie trailer. Lessons learned: Have a controlled environment without external interruptions

André: Increased HRV before the video and at the start of the scary

Mike: Increased HRV in between videos

Trevon: Not afraid of heights and watches a lot of scary movies

Josephine (f): Afraid of heights, but not videos of heights. Easily scared, but didn't find trailer scary. Laughing during facts video

Conclusion: Need controlled environment. Anticipation causes rise in HRV in between videos?

2015-11-06 and 2015-11-11 | Video test in controlled environment

More controlled environment

Person1: Didn’t know if he was afraid of heights. He is the last one to volunteer to go to the top of a ships mast. Tries to avoid horror movies. Quicktime opened at the beginning of video. Thought it was crazy with russian guys.

Person2: Small out of sync (recording started few seconds before video). Fun with the facts (banana)

Person3: Wasn’t scared of heights. He didn’t watch many horror movies. Thought it was crazy with russian guys

Pernille (f): Spoke to her quite a lot in the last 2 minutes. Not afraid of heights but does get excited by it. Hates horror movies. Thought the guy at the start was crazy

Kostas: not afraid of heights in general - thinking about safety rules for cranes. Would regularly watch and like horror films - tries to find movies that are realistically scary - had already watched the trailer - facts were interesting

Miguel: Is scared of heights. Watches horror films not so regularly but can watch

Person7: Small interruption in first video (staff had to pick up something). Asked him questions after we stopped the hr. Works with heights so not afraid. Doesnt watch any horror films normally. Has seen the trailer and heights video before

Person8: Asked him questions after. not normally afriad of heights. doesnt watch a lot of horror movies. nothing stood out particularly - pretty chilled

Person9: Asked him questions after. heights - not usually afraid of heights. horror films - doesnt watch a lot of horror films. anything else - nothing in particularly that stood out when watching

Further testing was done, which is documented in the scientific paper
