Client
Nex is a company from the US that creates motion-based, interactive games. They believe that physical activity is important, and their games can be played on a variety of devices with cameras. The games use motion sensors to track the player’s movements. Nex also offers a development kit so that other companies can create games for their platform.
Challenges
Nex struggled to capture unique user motions with limited training data for their pose estimation model development. Labeled datasets lacked variety, while vast public data (unlabeled) was hard to integrate effectively, hindering accurate motion-to-gameplay translation.
Solution
Label Your Data offered an on-demand business model for Nex. They sent flexible requests for different pose estimations based on project needs. Data annotators at Label Your Data used client-provided tools for pre-annotation capabilities using Nex’s existing models.
Data collection from public sources: Searching for publicly available data (no users’ data involved) for identified cases of interest (e.g., specific poses or workout exercises).
Skeleton annotation for pose estimation: Annotating missing skeletons and validating pre-annotations for almost 15K images.
