Method and apparatus for facilitating user interaction with a measurement instrument using a display-based control knob |
摘要 |
A method and apparatus for facilitating user interaction with a measurement instrument displays a control knob glyph corresponding to a user-adjustable parameter of the measurement instrument, the control knob glyph having an indicator and a partially circular drag area through which the indicator can be rotated. Inputs indicating amounts of rotational movement for the indicator can be received, and the location of the indicator within the drag area and the value of the parameter changed in response to such inputs.
