Abstract

The invention relates to a manually operable input device (1) having a sensor system (15) that comprises at least one rotary control knob (4) for detecting at least one movement characteristic variable. By predefining various movement patterns at the rotary control knob (4), various control commands can be generated. For this purpose, the input device (1) according to the invention comprises an evaluation unit (8) that compares the signal (13, 14) generated by the sensor system (15) with predefined rotational movement codes (C1-C16) and generates a code-dependent control command (16) if the predefined movement pattern or the corresponding signal (13, 14) matches a predefined rotational movement code (C1-C16).

Claims

1. A manually operable input device to control software applications or machines, having a rotary control knob for inputting a movement pattern in the form of several consecutive rotational movements, wherein

a sensor system is provided, which detects the movement direction as a first movement characteristic variable and the movement duration or the rotational speed as a second movement characteristic variable for a rotational movement executed on the rotary control knob,

an evaluation unit which compares a movement pattern provided on the rotary control knob with various predefined rotational movement codes which each comprise at least two code values, wherein at least one of the code values is a link of a movement direction to a movement duration or a rotational speed;

and

the input device is configured in such a way that it generates an allocated control command if a movement pattern input by the user on the rotary control knob matches one of the predefined rotational movement codes.

2. The input device according to claim 1, wherein the detection device is furthermore designed to detect a pause between two rotational movements.

3. The input device according to claim 2, wherein the detection device comprises a timer.

4. The input device according to claim 1, wherein a rotational movement code comprises at least two code values of movement characteristic variables and one or more time values.

6. The input device according to claim 1, wherein it comprises a device to recognize the end of a control demand executed on the rotary control knob.

7. The input device according claim 1, wherein the evaluation unit recognizes the end of a user input by checking whether the time duration following a rotational movement exceeds a time limit.

8. The input device according to claim 1, wherein the input device is realized as a 3D input device having an additional rotary wheel as a rotary control knob.

9. A method to control software applications or machines by a manually operable input device according to claim 1, comprising a rotary control knob, a detection device and an evaluation unit, comprising the following steps:

detection of a movement pattern inputted by a user on the rotary control knob by a sensor system which detects the movement direction as a first movement characteristic variable and the movement duration or the rotational speed as a second movement characteristic variable for each rotational movement executed on the rotary control knob;

comparison of the movement pattern, with which the rotary control knob is moved, with various predefined movement codes which each comprise at least two code values, wherein a code value is a link of a movement direction to a movement duration or a rotational speed; and

generation of a control command which is dependent on the respective rotational movement code, if the movement pattern matches one of the rotational movement codes.

12. The method according to claim 9, comprising the step:

detection of a pause between two rotational movements.

13. The method according to claim 9, comprising the step:

detection that a time limit is exceeded.
