A ring-type sensor device for a carrier

Abstract

The invention provides a ring type sensor device for a carrier. The ring type sensor device comprises an operating ring (1), a pressure sensing element (2), a sensor supporting structure (3), a signal conditioning unit (4), a control unit and the like. During use, the pressure of fingers of an operator on the ring is converted into resistance value change by virtue of a force sensing resistor integrated to each direction of the sensor, the signal conditioning unit is further converted into voltage value change, the control unit controls the movement of the movable carrier according to the acquired voltage value, and the moving track of an instrument needing to be operated can be intuitively and accurately controlled. The ring type sensor device disclosed by the invention has the advantages that the integration level is high, the operation is intuitive and simple, the error operation caused by external collision is avoided by virtue of the ring structure, and the man-machine interaction is friendly.

Description

technical field [0001] The invention relates to the field of human-computer interaction, specifically, to a ring-type two-dimensional pressure sensor device for trajectory control. Background technique [0002] At present, the domestic control of the mobile carrier or the mobile terminal of some medical instruments is generally operated by a remote control or a handle. The operator controls the lifting and advancing of the mobile carrier through the direction buttons or the handle on the remote control panel. The user needs to master the method of operation through certain learning and long-term adaptation, and the operation process is not intuitive enough. These two methods are not highly integrated between the remote control and the machine, and cannot shield misoperations caused by unintentional touches or drops of the remote control. In occasions such as patient lifters, misoperations will cause safety problems. Contents of the invention [0003] The present invention...

Users need to master the operation method through certain learning and long-term adaptation, and the operation process is not intuitive enough

The integration of the remote controller and the machine in these two methods is not high, and it cannot shield the misoperation caused by unintentional touch and drop of the remote controller. In the occasions such as patient lifters, misoperation will cause safety problems.
