*** 9660797 Matthews This Small Business Innovation Research Phase I project will develop a novel magnetic sensing technique that can be used in a variety of robotic and virtual reality operations to sense local positional accuracy to a very high degree of precision. By fixing an array of inexpensive magneto-resistive sensors to a nearby reference surface and attaching small transmit coils to the moving parts, robotic (or human) actions can be very accurately tracked, monitored and stored for future review. The position and orientation of each transmit coil with respect to the reference surface can be independently measured, with an expected positional accuracy of about one millimeter and rotational accuracy of better than one degree. The Phase I effort would be directed toward building a prototype system to further define the operational parameters and expected performance of such a system. Commercial applications include robotic control, virtual reality, telepresence (i.e., the combination of robotics and virtual reality), monitoring human performance (e.g., head, hand movements), and training. In the military, training systems and man-in-the-loop targeting applications would benefit from such a low cost, robust capability. With further development, detecting and tracking of larger objects such as concealed weapons (law enforcement need), cars/trucks (Intelligent Vehicle/Highway System applications) and airplanes over hundreds of meters will be possible. ***

*** 9660797 Matthews 这个小型企业创新研究第一阶段项目将开发一种新颖的磁传感技术，可用于各种机器人和虚拟现实操作，以非常高的精度感测局部位置精度。通过将一系列廉价的磁阻传感器固定到附近的参考表面并将小型发射线圈连接到移动部件，可以非常准确地跟踪、监控和存储机器人（或人类）的动作以供将来查看。每个发射线圈相对于参考表面的位置和方向可以独立测量，预期位置精度约为一毫米，旋转精度优于一度。第一阶段的工作将致力于构建原型系统，以进一步定义此类系统的操作参数和预期性能。 商业应用包括机器人控制、虚拟现实、远程呈现（即机器人和虚拟现实的结合）、监控人类表现（例如头部、手部运动）和培训。 在军事领域，训练系统和人机交互瞄准应用将受益于这种低成本、强大的功能。 随着进一步发展，探测和跟踪更大的物体将成为可能，例如隐藏武器（执法需要）、汽车/卡车（智能车辆/公路系统应用）和数百米以上的飞机。 ***
