I am a Graduate Research Assistant of Development and Immsersive Reality Lab(DAIR).
I am an animator and developer.
We scale the size of the character to test children's reaction towards these changes.
There are some models and animations that I build from scratch for the unity envrionment.

This is a side project that I conducted using FaceGen to generate avatars and test people's reaction towards their own avatar.
contact me
1. The photo quality matters. We need to make sure the light is right when taking the photo, otherwise it will change avatar’s skin color. Also we need to make sure no hair covers part of the face. Profile photo could be a good option.
2. Current Hairstyle options in FaceGen cannot satisfy their needs and some of them look weird.
3. Gender feature is not that obvious. Some female participants say their model looks like female without hair.
4. People usually see their reflections in the mirror. The 3D model is a little bit different to their perception, but it’s still acceptable.
5. Most participants have positive feeling towards their 3D models. Although there are some deficiencies like the nose part is dark from the front view, they still think the models look similar to real person.
