摘要： An electronic pointing or cursor control device (10) comprising a first chamber (15) and a second chamber (16), wherein: the two chambers (15, 16) are adjoined and separated by a fluid-tight separating wall (17); the first chamber (15) contains electronic components (22, 26); the second chamber (16) comprises an aperture; the second chamber (16) contains a ball (19), the ball (19) protruding through said aperture; the said separating wall (17) comprises an optically permeable region (18); and the electronic components (22, 26) include optical detection means (26) directed towards the optically permeable region (18) and the ball (19), the detection means (26) being operable in use to detect motion of the ball (19) and to generate electronic signals representative of said motion. The device (10) may be a trackball or a mouse. Also provided is an electronic pointing or cursor control device (10) comprising a ball (19) and optical detection means (26) responsive to movement of the ball (19), the optical detection means (26) being operable in use to detect motion of the ball (19) and to generate electronic signals representative of said motion, wherein the detection means (26) are mounted at an angular position (B) around the circumference of the ball (19) such that a radial line from the ball (19) to the detection means (26) forms a non-zero angle (α) with a diametric line (80) though the ball (19) normal to the mounting plane (82) of the device (10).

摘要： A trackball includes: a ball (23); a housing (25) including a recess (27) arranged to receive at least part of the ball (23); and only non-mechanical means for urging the ball (23) to remain in the recess (27), the non-mechanical means being arranged to improve the cleanability of the trackball (21). This arrangement may make the trackball more hygienic to use and easier to clean than conventional trackballs.
摘要翻译：一种轨迹球包括：球（23）; 包括凹部（27）的壳体（25），所述凹部布置成接收所述球（23）的至少一部分; 并且只有用于推动球23保持在凹槽27中的非机械装置，非机械装置被设置为改善轨迹球21的可清洁性。这种安排可能会使轨迹球使用更加卫生，并且比传统的轨迹球更容易清洁。

摘要： A pointing device such as a scrolling device or trackball, including a ball formed at least partially from an electrically conductive material, and a PCB including a capacitive proximity sensor, wherein movement data representative of ball movement is communicated by a controller to an interface such as a monitor screen, and wherein an electrical switch is actuable in response to the proximity of the sensed object to the ball, such that when a user is not in contact with or in close proximity to the ball, movement data will not be communicated by the controller to the interface.
摘要翻译：诸如滚动装置或轨迹球的指示装置，包括至少部分地由导电材料形成的球，以及包括电容式接近传感器的PCB，其中表示球运动的运动数据由控制器传送到诸如监视器屏幕，并且其中电开关响应于感测对象与球的接近而可启动，使得当用户不与球接触或非常接近球时，运动数据将不被通过控制器到界面。
