A Position Sensing Glove to Aid Ankle-Foot Orthosis Diagnosis and Treatment

A position sensing glove called SmartScan, which creates a 3D virtual model of a real object, is presented. The data from the glove is processed by a volume minimization algorithm to validate the position sensor data. This allows only data from the object's surface to be retained. The data validation algorithm allows the user to progressively improve an image by repeatedly moving their hand over the object. In addition, the user can choose their own balance between feature resolution and invalid data rejection. The SmartScan glove is tested on a foot model and is shown to be robust against motion artifacts, having a mean accuracy of 2.9 mm (compared to a 3D model generated from optical imaging) without calibration.

Automated summary

The SmartScan glove is a position sensing glove that creates a 3D virtual model of a real object by processing data and validating position sensor data through an algorithm, retaining only the data from the object's surface. Users can progressively improve an image by moving their hand over the object and choose their own balance between feature resolution and invalid data rejection. Tested on a foot model, the SmartScan glove demonstrates robustness against motion artifacts with a mean accuracy of 2.9 mm, without the need for calibration.
