Brian Bear: Varied Data Sampling

Brian Bear (a pseudonym for the child based on their stuffed animal’s name) created gestures for their stuffed animal being in a bedroom: sleep, play game, and dance. While recording samples of each gesture, the researcher noticed that Brian Bear performed each gesture differently. When asked to explain their intentions, Brian Bear explained that they wanted a wider range of movements for the computer to recognize as one gesture. In the example of sleep, this resulted in three different gesture samples: lying still, sleeping on one side, and rolling over.

Three Different Samples for Sleep Gesture

When Brian Bear described their process for recording three different sleep samples, they explained that it was based on how they sleep, which looks different throughout the night.

While this mindset could work on a large data set with many sample recordings, it’s not ideal to have such varied recordings for a small sample size of N=3.
