    • Position and orientation of a stylus with respect to a sensing surface of a host electronic device are provided by sensing first and second electromagnetic fields at a sensing surface, the first and second electromagnetic fields varying in strength in response to stylus orientation, and determining the orientation from a difference in sensed field strength between the first and second electromagnetic fields. The first and second electromagnetic fields may be produced by proximal and distal electromagnetic transmitters of the stylus. The orientation may be used, for example, to control the response of a computer drawing application executed on the host electronic device.
    • 通过感测表面上的第一和第二电磁场来检测触控笔相对于主机电子设备的感测表面的位置和方位,第一和第二电磁场响应于触针取向而强度变化,并且确定取向 从第一和第二电磁场之间的感测场强的差异。 第一和第二电磁场可以由触笔的近端和远端电磁发射器产生。 该方向可以用于例如控制在主机电子设备上执行的计算机绘图应用的响应。
