Motion Capture — Week 1

Moodboard:

I am interested in visualizing people’s emotion. For the project, I want to visualize “pressure”. I’d like to have strings tangled on a human body which symbolize the accumulation of stress from our daily life. Audience can also get involved in the work by using their phone to interact with it. On their phone, they can see the source of pressure randomly, like pressure from pressure from school work, their job or so. And then they can tap on the source of pressure which can be simultaneously added to the character’s body and accumulate as tangled string.

Documentation for the Mocap Lab 1

Calibration

1. Make sure there is no shining stuff in the room. Open Motive.
2. Start wanding. Have one people keep the makers and walk around in the room. Stop it until the value of each camera over 10,000.
3. Apply data.
4. Put the Z-axis in the center of the room.
5. Finish calibration.

Play around with makers

1. Have one person take the maker(s) (or multiple people)and record its data.
2. Save the data and rename it as unique IDs.

Stream the data on another computer

1. In Motive, select data streaming under “View” tab to sync the rigid bodies to Unreal Engine on another PC. Its IP address is 192.168.1.5.
2. In Unreal, create OptiTrack client origin. Its IP address is 192.168.1.2.
3. Under Optitrack rigid body actor, add a component to it. The tracking ID should be correspond to the traker ID on server’s side. (For example, 1–4)
4. Have the live streaming motion capture in Unreal!
