Advanced body motion and location tracking in active sports goggles

拟议的项目是SFU的Park博士和Recon Instruments Inc.之间的合作研究伙伴关系。Recon开发和销售一种显示系统（微光显示器），用于滑雪和滑雪板等活跃运动中佩戴的护目镜。配备Recon系统的护目镜还配备了一个完全嵌入式计算机系统和一系列传感器。这使得可以实时呈现与用户的当前活动相关的信息。这样的信息显示包括诸如佩戴者的当前速度、高度、位置和地图的数据。可用的传感器包括加速度计、陀螺仪和磁力计，它们一起形成惯性测量单元（IMU）。使用IMU的输出，惯性导航系统（INS）结合重力场和地球磁场模型来估计物体的位置和取向。当与来自其他机载传感器（即，全球定位系统（GPS）和高度计）的信号组合时，这些传感器形成GPS/INS系统，其可以准确地识别所执行的活动的类型（例如，跳跃）以及帮助个人导航。

The proposed project is a collaborative research partnership between Dr. Park of SFU and Recon Instruments Inc. Recon develops and markets a display system (micro-optic display) for goggles worn in active sports such as skiing and snowboarding. Goggles instrumented with Recon's system are also equipped with a fully embedded computer system and a collection of sensors. This makes it possible to present information related to the user's current activity in real-time. Such an information display includes data such as the wearer's current speed, altitude, location and maps. The available sensors include an accelerometer, gyroscope, and magnetometer that together form an inertial measurement unit (IMU). Using the outputs of an IMU, an inertial navigation system (INS) estimates a body's position and orientation in connection with gravitational field and Earth's magnetic field models. When combined with signals from the other on-board sensors, i.e. global positioning system (GPS) and altimeter, these sensors form a GPS/INS system that could accurately recognize the type of activity performed (e.g., jumps) by the wearer as well as aiding in personal navigation.
