Gaitanalyzer is a tool that analyzes gait at home, helping users understand their health status. By uploading short videos of left-to-right movement, users can conduct gait analysis and obtain detailed gait data and interpretations. The product implements an automatic gait analysis algorithm based on an unlabeled pose estimation model, enabling video analysis on a local computer. It provides pose labeling, distance, peak and minimum value plotting, along with gait data display and download. Furthermore, Gaitanalyzer utilizes the Llama2 large language model to explain gait patterns to users in simple terms. Users can access Gaitanalyzer at https://gaitanalyzer.health, where videos are stored on the server. Alternatively, users can run it locally using docker, storing videos on their computers.
