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.的合作研究伙伴关系。Recon开发和营销一种用于滑雪和单板滑雪等运动项目中佩戴的护目镜的显示系统(微型光学显示器)。配备了Recon系统的护目镜还配备了一个完全嵌入式的计算机系统和一系列传感器。这使得实时呈现与用户当前活动相关的信息成为可能。这样的信息显示包括佩戴者的当前速度、海拔、位置和地图等数据。可用的传感器包括加速度计、陀螺仪和磁力计，它们一起构成了惯性测量单元(IMU)。利用IMU的输出，惯性导航系统(INS)根据引力场和地球磁场模型估计物体的位置和方向。当与来自其他车载传感器(即全球定位系统(GPS)和高度计)的信号相结合时，这些传感器形成一个GPS/INS系统，可以准确识别佩戴者进行的活动类型(例如跳跃)，并帮助个人导航。

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.
