Xsens has launched BASE, an online technology platform with a community forum and a knowledge base on 3D motion tracking technology and products. On BASE.xsens.com, the knowledge base contains inside information about micro-electro-mechanical system (MEMS) sensors, inertial measurement units (IMU), sensor fusion algorithms, body-motion tracking and motion capture. It also provides best practices, tips and tricks for the use of Xsens’ successful products the MTi series, the MTw and the MVN wearable motion capture solutions. A second section of BASE is the community forum with direct access to Xsens’ engineers and other Xsens users. The knowledge base and community forum make it easier to integrate the MTi or MTw and to get the most out of MVN. If a question is not answered in the knowledge base, it is straightforward to ask a question to the community. With short response times from either other Xsens users or the entire Xsens engineering team, the user community is a quick way to continue development, Xsens said. BASE is a next step by Xsens to support the growing community and interest in inertial technology. It further enhances the interaction between users and Xsens. “Although Xsens makes it easy to use inertial technology in their applications, the underlying technology is complex and there are many features for specific applications,” said Remco Sikkema, Xsens marketing manager. “Understanding the technology makes it easier to integrate the products and be successful with Xsens.” With BASE, engineers and engineering teams in the Xsens community can come closer together. The primary goal is to make Xsens customers more successful by providing a platform to exchange information. There is no need to register for BASE to access the community forum and the knowledge base. To ask questions or comment on articles, registration is possible via SSO or email.
