Abstract

An apparatus for presenting a time-variant information element in a vehicle, which has a steering wheel (1602), comprises one or more remotely and individually controllable tactile pads (1620), which produce a tactile sensation in response to a respective pad output signal, which is produced by a controller (CTRL). The tactile pads are positioned or adapted to be positioned on the steering wheel (1602) or proximate to it, such that they can be touched by at least one hand (1610,1612) of the vehicle driver while driving the vehicle. The apparatus further comprises means for determining the time-variant information element to be presented and for applying the determined time-variant information element to the controller and means for encoding the determined time-variant information element by the controller into temporal variations of the one or more pad output signals.

Claims

1. An apparatus for presenting a time-variant information element in a vehicle, which has a steering wheel, the apparatus comprising:

a plurality of remotely and individually controllable tactile pads, each of which is operable to produce a tactile sensation in response to a respective pad output signal, wherein a plurality of pad output signals are produced by a controller, and wherein the plurality of tactile pads are positioned or adapted to be positioned on the steering wheel or proximate to the steering wheel, the plurality of tactile pads being configured to be touched by at least one hand of a vehicle driver while driving the vehicle;

means for determining the time-variant information element to be presented and for applying the determined time-variant information element to the controller; and

means for encoding the determined time-variant information element by the controller into temporal variations of the plurality of pad output signals, wherein the encoding comprises encoding the time-variant information element to a simultaneous set of states of the plurality of tactile pads;

whereby the apparatus is configured to present the time-variant information element to the vehicle driver via the tactile sensation.

2. The apparatus according to claim 1, wherein the time-variant information element has a current value and a current range and the encoding comprises assigning a portion of the current range to each tactile pad;

and activating one of the plurality of tactile pads whose assigned range includes the current value of the time-variant information element.

3. The apparatus according to claim 2, wherein the encoding further comprises activating two neighbouring tactile pads simultaneously if the current value of the time-variant information element is within a predetermined margin from the average value of a union of velocity ranges associated to the two neighbouring tactile pads.

4. The apparatus according to claim 1, further comprising one or more static formations positioned so as to guide the vehicle driver'"'"'s fingers to the plurality of remotely and individually controllable tactile pads.

5. The apparatus according to claim 4, wherein at least one of the remotely and individually controllable tactile pads at least partially overlaps at least one of the one or more static formations.

6. The apparatus according to claim 4, wherein at least one of the one or more static formations at least partially overlaps at least one of the remotely and individually controllable tactile pads.

7. The apparatus according to claim 1, wherein the encoding comprises enabling presentation of the time-variant information element for a predetermined period of time in response to at least one of:

a detection of a change of a value of the time-variant information element exceeding a predetermined threshold;

or

a detection of a predetermined act of the vehicle driver.

8. The apparatus according to claim 1, wherein the remotely and individually controllable tactile pads comprise at least one electromechanical stimulus generator.

9. The apparatus according to claim 1, wherein the remotely and individually controllable tactile pads comprise at least one capacitive electro-sensory interface.

10. The apparatus according to claim 1, wherein the remotely and individually controllable tactile pads comprise at least one device having means for moving a formation to one of multiple different positions according to the determined time-variant information element.

11. The apparatus according to claim 1, wherein the time-variant information element is selected from a group which comprises:

the vehicle'"'"'s speed;

indication of a current speed limit or a change thereof, as determined by a navigation device;

a deviation of the vehicle'"'"'s speed from the current speed limit, wherein the current speed limit is determined by a navigation device; and

a deviation from a normal range in one or more running parameters of an engine of the vehicle.

12. A method for presenting a time-variant information element in a vehicle, which has a steering wheel, the method comprising:

providing the steering wheel with two or more remotely and individually controllable tactile pads, each of which is operable to produce a tactile sensation in response to a respective pad output signal, wherein a plurality of pad output signals are produced by a controller, and wherein the two or more tactile pads are positioned on the steering wheel or proximate to the steering wheel, the two or more tactile pads being configured to be touched by at least one hand of a vehicle driver while driving the vehicle;

determining the time-variant information element to be presented and applying the determined time-variant information element to the controller; and

encoding the determined time-variant information element by the controller into temporal variations of the plurality of pad output signals, wherein the encoding comprises encoding the information element to a simultaneous set of states of the two or more tactile pads.
