Gait monitoring for human activity recognition using perceptive shoe based on hetero-core fiber optics

Gait monitoring system for human activity recognition is demonstrated using a perceptive shoe based on hetero-core fiber optics. The insole with hetero-core fiber monitors foot pressure without temperature dependency and constraint to human body. Monitoring test was performed by a human subject doing basic activities which are walking, walking on the spot, running, standing, and sitting on a chair. The human activities were successfully monitored by means of perceptive shoe using hetero-core fiber optics. In addition, walking on the spot and standing were identified using only front weight response.
