About

AngleLab

Features
Read full description

AngleLab is an app that attaches two smart sensors and acquires the angle between segments. ■Overview Since it is a digital goniometer application between two segments, when applied to the human body, the relative angle between the parts where the sensor is attached can be obtained as 3-axis data. Sensor data can be monitored in real-time while being recorded on an iPad. In addition, by enabling video recording with the device’s video camera, it is possible to synchronize sensor data and video and play back after measurement. In addition, the resulting data can be output externally as CSV. ■For checking body range of motion! For example, when sensors are attached to the pelvis and thigh, joint angles of X, Y, Z axis: flexion/extension, adduction/abduction, internal rotation/external rotation can be obtained in real time, graphed, and numerical values can be output as CSV. ■ Requirements Xsens DOT sensor is prerequisite to use this app. In addition, it is necessary to obtain a license key issued by HELTEC Co., Ltd.
