DE10300469A1 - Operating-information system with active dynamic input-output, whereby a user receives a tactile response confirming an input or control device has been successfully used so that device operation is made safer and simpler - Google Patents

Abstract

Operating-information system with active dynamic input-output, whereby information or states of a machine, control device, computer, program, etc. are fed back to a user in a tactile manner. E.g. when a user presses a key he receives a tactile stimulus to confirm the key has been pressed.

Description

The invention relates to a method that the conventional communication between people and machine expanded by another information channel.

Operating systems and components in the usual design such as switches, buttons, keyboards, As a rule, touchscreens etc. are only intended for entering commands.

Feedback is only visually displayed via this to a limited extent, e.g. B. via status leds in the keyboard or illuminated buttons and switches.

For a real confirmation of the entry, a visual "check" is therefore necessary. B. on Screen necessary, which is usually not in the direct field of vision of the actual activity. Acoustic confirmation of an entry is also problematic and in many areas (e.g. high noise level) excluded.

The invention is therefore based on the object of a direct ergonomic and genuine Giving feedback / information without the operator from his actual job or Distract task.

The problem is solved in such a way that the machine, environmental or Program status, notes or other information, directly from the operating system, Information system or another component using actuators such. B. vibrators, shakers etc. active on the executing, entering or connected part of the body (e.g. hand, finger, foot, Buttocks, etc.).

The procedure ensures that the sense of touch and feel actively communicate with Machines are addressed and, depending on the design, all areas of the body are addressed can be. In addition, the natural perception of the effort (Force feedback) are transmitted (for functional description see page 2). For example, a correct keyboard input directly on the finger using tactile Acknowledgment is acknowledged, but an illogical one is not acknowledged.

A critical command can be confirmed, for example, with a vibration, etc. Furthermore, the combination - especially with electronic keyboard technologies and components such as B. HF / capacitive, FSR, piezo and infrared keyboards etc. -, states of the machine can be felt or recorded.

Here is an example: Parallel to the weight on a winch, the "Up" button must be strong or operated less strongly (force feedback) Or: Keys that would allow illogical entries in a certain mode simply locked in this mode, thus interactive communication via a previously unused "channel".

Of course, information can also be entered independently of any one Body part. This enables the driver to take a critical trip over a slippery road Be informed about the seat that the vehicle is about to break out. Would When the vehicle actually breaks out, this is first perceived via the buttocks.

If you get too close to the guardrail by car, the corresponding side of the vibrates Driver seatback. GPS navigation using actuators installed in the seat has the advantage that this does not distract or burden the driver, since this "communication channel" is unloaded. By responding directly to the executive body, the response time is shortened and the visual and acoustic information processing relieved.

Assigning the information to different parts of the body supports the natural one Signal processing. It also increases operator awareness of the impact of his activities sensitized. So to speak, the operator gets more feeling for his Action. The "information channel" about the seat when driving or other sedentary activities are never interrupted.

An increase in productivity, fewer mistakes, accidents and an intuitively subconscious Learning is the result.

functional Specifications Force feedback

For the functional sequence of a button with force feedback using the example of crane operation, using a piezo button.

The piezo button outputs a voltage proportional to the actuation pressure. A sensor detects the weight of the load to be lifted, for example via a current measurement on the motor. AD / A The converter circuit compares the measurement signal with the actuation voltage from the button, until the voltage (or operating pressure) is reached to lift the load. For applications using FSR technology, the supply voltage of the pressure-dependent voltage divider corresponding to the load changed (higher load = lower Supply voltage. with the result that you have to press harder).

With infrared or capacitive buttons, e.g. B. the size of the contact area can be evaluated, which increases with higher finger pressure.

Active haptic information

Unlike "normal" buttons, which have passive, mechanical haptic feedback Output (tactility), the haptic information is generated via a separate unit. This Unit (e.g. lifting magnet) generates a blow to the operating front when activated, which is "recorded" by the executive body. It is not necessary that the Actuator is placed directly under the button (b). So it is z. B. possible a complex control unit to be provided with only one actuator (a).
