Abstract
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.

A method for facilitating user interaction with a measurement instrument comprising the steps of:
- displaying a control knob glyph corresponding to a user-adjustable parameter of the measurement instrument, the control glyph having both an indicator and a partially circular drag area through which the indicator can be rotated in both a clockwise and a counterclockwise manner as a first portion of the control knob glyph and both an increment and a decrement button as a second portion of the control knob glyph;
- receiving an input indicating an amount of rotational movement for the indicator;
- and
- changing the location of the indicator within the partially circular drag area and a value of the parameter in response to the input.
A method for facilitating user interaction with a measurement instrument comprising the steps of:
- displaying 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 in both a clockwise and a counterclockwise manner;
- receiving an input indicating an amount of rotational movement for the indicator;
- changing the location of the indicator within the drag area and a value of the parameter in response to the input if the desired change is greater than a particular value.
A machine-readable medium having stored thereon a series of instructions which, when executed by a processor of a measurement instrument, facilitate user interaction with the measurement instrument by causing the processor to:
- display a control glyph corresponding to a user-adjustable parameter of the measurement instrument, the control knob glyph having both an indicator and a partially circular drag area through which the indicator can be rotated in both a clockwise and a counterclockwise manner as a first portion of the control knob glyph and both an increment and a decrement button as a second portion of the control knob glyph;
- receive an input indicating an amount of rotational movement for the indicator;
- and
- change the location of the indicator within the drag area and a value of the parameter in response to the input.
A measurement apparatus comprising:
- a display device;
- and
- a control subsystem coupled to the display device to
- provide a control knob glyph on the display device corresponding to a user-adjustable parameter of the measurement apparatus, the control knob glyph having both an indicator and a partially circular drag area through which the indicator can be rotated in both a clockwise and a counterclockwise manner as a first portion of the control knob glyph and both an increment and a decrement button as a second portion of the control knob glyph,
- receive an input indicating an amount of rotational movement for the indicator, and
- change the location of the indicator within the drag area and a value of the parameter in response to the input.
