Gait Cycle Dataset
Dataset Information:
Walking is a form of mobility that represents the most important human physical activity due to its great impact on the majority of daily living activities. To understand better the human walking, it may be helpful to quantify gait dynamics accurately. This dataset represents a real-life benchmark in the area of gait cycle recognition applications. This dataset contains measures of gait from five healthy subjects with different profiles (mean age: 27 years old, mean weight: 79 kg). This dataset includes the vertical Ground Reaction Force (vGRF) records of subjects during the walk. Each subject wearing the in-shoe pressure sensors performed thirty gait cycles along a straight line. The participants were instructed to walk in their own style. In this experiment, the F-Scan system from Tekscan, an in-shoe pressure measurement system, is used to collect force and pressure measurement data wirelessly and without altering the natural movement of the subject. High-resolution, ultra-thin (.015mm) sensors are placed underneath the plantar surface of each foot to characterize the interaction between the foot and the ground. A wireless datalogger attached to the subject’s waist transmits pressure and force data from the in-shoe sensors in real time through a WiFi network to the host computer (as shown in Figure 1). The F-Scan sensor measures the subject’s plantar pressure and is composed of 960 individual pressure sensing locations, also called "sensels". The sensels are arranged in rows and columns on the sensor (as shown in Figure 1 (c)). The output of each sensel is divided into 256 increments with 8 Bit Digital Pressure and a resolution of 0.2N. The F-scan operates with a scan rate of up to 100 Hz.
This dataset is fully labeled by analyzing the vertical Ground Reaction Force (vGRF) profiles provided by the in-shoe pressure sensors. The normal gait cycle involving six gait phases is considered in this dataset. The considered gait cycle phases are: Loading Response (S1); Mid-Stance (S2); Terminal Stance (S3); Pre-Swing (S4); Mid-Swing (S5); and Terminal Swing (S6). Figure 2 shows an example of gait-cycle phases manual labelling.
