Abstract

Apparatuses, computer programs and methods are provided. A method includes causing display on an autonomous or semi-autonomous vehicle of a dynamic sign acknowledging the presence of at least one road user.

First claim

The invention claimed is:

1. A method comprising:
causing display, on an autonomous or semi-autonomous vehicle, of a dynamic sign acknowledging the presence of at least one road user that is visible from outside the autonomous or semi-autonomous vehicle, wherein the dynamic sign includes a directional indication associated with the acknowledgement that depends on a direction of at least one road user relative to the autonomous or semi-autonomous vehicle.

2. The method as claimed in claim 1 , wherein the dynamic sign is configured to notify the at least one road user that the autonomous or semi-autonomous vehicle has detected the at least one road user.

3. The method as claimed in claim 1 , wherein the dynamic sign is configured to notify at least one further road user that the autonomous or semi-autonomous vehicle has detected the at least one road user.

4. The method as claimed in claim 3 , wherein the dynamic sign is configured to warn the at least one further road user of the presence of the at least one road user.

5. A non-transitory computer readable medium storing computer program code, that when performed by at least one processor, causes an apparatus to at least:
causing display, on an autonomous or semi-autonomous vehicle, of a dynamic sign acknowledging the presence of at least one road user that is visible from outside the autonomous or semi-autonomous vehicle, wherein the dynamic sign includes a directional indication associated with the acknowledgement that depends on a direction of at least one road user relative to the autonomous or semi-autonomous vehicle.

6. An apparatus, comprising:
at least one processor; and
memory storing computer program code configured to, when performed by the at least one processor, cause the apparatus to at least:
cause display, on an autonomous or semi-autonomous vehicle, of a dynamic sign acknowledging the presence of at least one road user that is visible from outside the autonomous or semi-autonomous vehicle, wherein the dynamic sign includes a directional indication associated with the acknowledgement that depends on a direction of at least one road user relative to the autonomous or semi-autonomous vehicle.

7. An autonomous or semi-autonomous vehicle comprising the apparatus as claimed in claim 6 .

8. The apparatus as claimed in claim 6 , wherein the dynamic sign is configured to notify the at least one road user that the autonomous or semi-autonomous vehicle has detected the at least one road user.

9. The apparatus as claimed in claim 6 , wherein the dynamic sign is configured to notify at least one further road user that the autonomous or semi-autonomous vehicle has detected the at least one road user.

10. The apparatus as claimed in claim 9 , wherein the dynamic sign is configured to warn the at least one further road user of the presence of the at least one road user.

11. The apparatus as claimed in claim 6 , wherein the computer program code is configured to, when performed by the at least one processor, cause the apparatus to: control the dynamic sign to comprise at least one symbol representing the at least one road user the presence of which is being acknowledged.

12. The apparatus as claimed in claim 6 , wherein the dynamic sign comprises multiple dynamic elements.

13. The apparatus as claimed in claim 6 , wherein the dynamic sign comprises an avatar and the appearance of the avatar is altered to acknowledge the presence of the at least one road user.

14. The apparatus as claimed in claim 6 , wherein the computer program code is configured to, when performed by the at least one processor, cause the apparatus to: cause detection of the at least one road user.

15. The apparatus as claimed in claim 6 , wherein the computer program code is configured to, when performed by the at least one processor, cause the apparatus to: cause display of a dynamic sign to acknowledge the presence of at least one road user to multiple, different road users on a single display on the autonomous or semi-autonomous vehicle.

16. The apparatus as claimed in claim 6 , wherein the computer program code is configured to, when performed by the at least one processor, cause the apparatus to: cause display of a dynamic sign to acknowledge the presence of at least one road user on multiple displays on the autonomous or semi-autonomous vehicle.

17. The apparatus as claimed in claim 6 , wherein the computer program code is configured to, when performed by the at least one processor, cause the apparatus to: cause simultaneous display of a plurality of dynamic signs acknowledging the presence of a plurality of different road users.

18. The apparatus as claimed in claim 6 , wherein the dynamic sign acknowledges the presence of a first road user, and the directional indication depends on a direction of the first road user relative to the autonomous or semi-autonomous vehicle.

19. The apparatus as claimed in claim 6 , wherein the dynamic sign acknowledges the presence of a first road user, and the directional indication depends on a direction of a second road user relative to the autonomous or semi-autonomous vehicle, the second road user being different from the first road user.

20. The apparatus as claimed in claim 19 , wherein the first road user is a pedestrian and the second road user is a vehicle.
