    • A digital input device for entering data into a digital system, comprises at least two remote sensors and a control unit. A working area is set up in proximity to the sensors and the position of an object within the working area is detected by the input device based on data provided by each sensor and transmitted, by said control unit, to said digital system. The position of an object outside said working area, if detected by said input device, is rejected by said control unit and is not transmitted to said digital system. The sensors can be ultrasonic sensors and the object can be a part of the body of a user. Use of a third sensor allows three-dimensional detection of the object.
    • 用于将数据输入数字系统的数字输入设备包括至少两个远程传感器和控制单元。 工作区域设置在传感器附近,并且基于由每个传感器提供的数据由输入设备检测到工作区域内的对象的位置,并由所述控制单元发送到所述数字系统。 如果由所述输入装置检测到,所述工作区域外的物体的位置被所述控制单元拒绝,并且不被发送到所述数字系统。 传感器可以是超声波传感器,物体可以是使用者身体的一部分。 使用第三个传感器可以对物体进行三维检测。
