On July 3, 2017, Goncalo, Dario, and I spent the day fitting the interactive station with all of its bits and pieces. We needed to install the monitor (which displays the visual content), the faceplate (which includes the cameras for taking up-close videos of participants eyes), one feedback monitor, and the Intel NUC (a mini-computer) which would play video content to the monitor and store the video recordings from the eye cameras.
Many other friends and colleagues came to give their support throughout the day. Below is a time-lapse video of our final day before installation!
Photos from that day:
Clive Ramble and Hazel Garnade of Sol Vin, who built the outer casing for the interactive station.
The interactive station lived in one of the loading docks at the SWC while we worked on installing and tweaking its guts.
Adam checks out the interactive station as we begin working on installing all of its bits and pieces.
Making sure all of our components work the way we think they do, and interact with each other from inside Bonsai (visual programming environment) the way we think they should.
Goncalo and Dario test the eye-tracking cameras from Pupil Labs.
Dario shows off our feedback monitor, version 1. We tested all of the interactions between our components before placing them inside the interactive station.
Goncalo peers through the face plate of the interactive station, as we figure out how to place the eye cameras, and where to place the webcam (verifies what the participant is watching on the monitor inside the interactive station) and the electronics controlling our face detector (a photo-diode that sits in the foam lining of the face plate; participants must press their face into the foam and cover the photo-diode in order to trigger the interactive station to play a movie).

Another view of Goncalo as he tweaks the eye cameras. In this photo, the infrared lights on the eye cameras show up as purple dots.

A view through the face plate into the interactive station. Camera placement is still not final, which is why they are stuck onto the face plate using Blue Tac.
Labmates J and Joana visit the loading dock to check our progress and bring us some much needed comic relief.
