摘要： A two-axis ball-based cursor control apparatus is provided, which includes a housing; a spherical ball contained partially within the housing; two rotors in contact with the spherical ball and two corresponding axles; two screw devices associated with each rotor-axle pair, each screw device having a continuous helical thread; a plurality of light sensors, each associated with a screw device; and a means for processing the signal from the light sensors. When the spherical ball is rotated by the user, its motion about each axis of rotation is translated to one of the screw devices by means of the corresponding rotor-axle pair. The rotation of the screw devices causes the helical thread on each to momentarily interrupt the light beam generated by each sensor at least once during each revolution of the screw device, thereby generating a signal which is translated into two-dimensional motion of a cursor on an electronic display screen.

摘要： A two-axis ball-based cursor control apparatus with tactile feeling is provided, which includes a housing; a spherical ball contained partially within the housing and having a plurality of recesses distributed about its outer surface; two pairs of spring biased sensor mechanisms each including a probe, a spring, and a transducer; and a means for processing the signals received from the sensor mechanisms. Each of the four probes is positioned so that it rests within one of the recesses on the spherical ball when the ball is stationary. As the ball is rotated, the probes are pushed up and out of the recesses by the ball, causing the corresponding springs to alternately compress and decompress, before the probes come to rest in adjacent recesses. Each transducer generates an electrical signal corresponding to the rate of compression and decompression in the corresponding spring. The signal processing means then translates the signals from each of the transducers into movement of a cursor on an electronic display screen which corresponds to the rotation of the spherical ball about each of its axes.

摘要翻译： 提供一种具有触感的双轴球型光标控制装置，其包括壳体; 球形球部分地包含在壳体内并且具有围绕其外表面分布的多个凹部; 两对弹簧偏置传感器机构，每个包括探针，弹簧和换能器; 以及用于处理从传感器机构接收的信号的装置。 四个探针中的每一个被定位成使得当球静止时，四个探针中的每一个都位于球形球中的一个凹槽内。 当球旋转时，探针通过球向上推动并离开凹槽，导致相应的弹簧交替地压缩和减压，然后探头在相邻的凹槽中静止。 每个传感器产生对应于相应弹簧中的压缩和减压速率的电信号。 然后，信号处理装置将来自每个换能器的信号转换成电子显示屏上的光标移动，该移动对应于围绕其每个轴的球形球的旋转。
