Senno Gait is a novel portable system to address the current issues. The smart insole integrates low cost sensors and computes important gait features. In this way, patients or users can wear Senno Gait for gait analysis in daily life instead of participating in gait lab experiments for hours. Senno Gait’s portable sensing system and effective feature extraction algorithm enables precise gait analysis. Furthermore, taking advantage of the affordability and mobility of Senno Gait, pervasive gait analysis can be extended to many potential applications, life behavior analysis and networked wireless health systems.
