Abstract

Provided are systems, methods, and media for tactile map-based navigation on a reconfigurable display surface. An example method includes receiving an input destination for a user, generating a navigational route to the destination based on a current location of the user, and transmitting a control signal to the reconfigurable display surface to cause the mobile display surface to render the navigational route on a map of a geographic area. The rendering of the navigational route includes changing topography of the reconfigurable display surface such that a first three-dimensional (3D) shape is formed on the map at a position of the current location and a second 3D shape is formed on the map at a position of the destination.

First claim

What is claimed is:

1. A computer-implemented method for tactile map-based navigation on a reconfigurable display surface, the method comprising:
receiving, by a system comprising one or more processors, an input destination for a user;
generating, by the system, a navigational route to the destination based on a current location of the user; and
transmitting, by the system, a control signal to the reconfigurable display surface to cause the reconfigurable display surface to render the navigational route on a map of a geographic area, wherein the rendering of the navigational route includes physically changing a topography of the reconfigurable display surface such that a first three-dimensional (3D) shape is formed on the map at a position of the current location and a second 3D shape is formed on the map at a position of the destination,
wherein the configuration display surface comprises a plurality of movable grid cells and the physically changing a topography comprises altering a height or depth of one or more of the movable grid cells on the surface of the configurable display surface, and
the transmission of the control signal further causes haptic feedback comprising a vibration to be provided to the user in response to a touch by the user of at least one of the first 3D shape or the second 3D shape.

2. The computer-implemented method of claim 1 further comprising:
transmitting a second control signal to the reconfigurable display surface to cause the reconfigurable display surface to position the first 3D shape closer to the position of the second 3D shape on the reconfigurable display surface as the current location of the user approaches the destination.

3. The computer-implemented method of claim 1 , wherein the reconfigurable display surface is configured to announce a distance to the destination in response to receiving a touch by the user of the first 3D shape.

4. The computer-implemented method of claim 1 , wherein the reconfigurable display surface is configured to announce at least one of a name of the destination or address of the destination in response to receiving a touch by the user of the second 3D shape.

5. The computer-implemented method of claim 1 , wherein receiving the input destination includes receiving, by the system, a range of input destinations for the user, wherein the destination of the navigational route is a first destination of the range of input destinations, wherein the method further includes:
transmitting a second control signal to the reconfigurable display surface to cause the reconfigurable display surface to render a third 3D shape on the map for each destination of the range of input destinations other than the first destination, and rendering a polyline on the map, wherein the polyline connects each destination in the range of input destinations; and
changing the destination of the navigational route from the first destination to a second destination of the range of input destinations, wherein the second destination is selected in response to receiving a touch input by the user in which the user touches the first 3D shape for a period of time, wherein the reconfigurable display surface is configured to cycle, during the period of time, between destinations of the range of input destinations.

6. The computer-implemented method of claim 1 , wherein the rendering of the navigational route further includes changing topography of the reconfigurable display surface such that a 3D line representation of the navigational route is formed on the map, wherein the method further includes:
generating one or more alternate navigational routes to the destination based on the current location of the user;
selecting an alternate navigational route of the one or more alternate navigational routes in response to receiving a touch by the user of the 3D line; and
transmitting a second control signal to the reconfigurable display surface to cause the reconfigurable display surface to render the selected alternate navigational route.

7. A computer program product for tactile map-based navigation on a reconfigurable display surface, the computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by a system comprising one or more processors to cause the system to perform a method, the method comprising:
receiving, by the system, an input destination for a user;
generating, by the system, a navigational route to the destination based on a current location of the user; and
transmitting, by the system, a control signal to the reconfigurable display surface to cause the reconfigurable display surface to render the navigational route on a map of a geographic area, wherein the rendering of the navigational route includes physically changing a topography of the reconfigurable display surface such that a first three-dimensional (3D) shape is formed on the map at a position of the current location and a second 3D shape is formed on the map at a position of the destination,
wherein the configuration display surface comprises a plurality of movable grid cells and the physically changing a topography comprises altering a height or depth of one or more of the movable grid cells on the surface of the configurable display surface, and
the transmission of the control signal further causes haptic feedback comprising a vibration to be provided to the user in response to a touch by the user of at least one of the first 3D shape or the second 3D shape.

8. The computer program product of claim 7 , wherein the method further includes:
transmitting a second control signal to the reconfigurable display surface to cause the reconfigurable display surface to position the first 3D shape closer to the position of the second 3D shape on the reconfigurable display surface as the current location of the user approaches the destination.

9. The computer program product of claim 7 , wherein the reconfigurable display surface is configured to announce a distance to the destination in response to receiving a touch by the user of the first 3D shape.

10. The computer program product of claim 7 , wherein the reconfigurable display surface is configured to announce at least one of a name of the destination or address of the destination in response to receiving a touch by the user of the second 3D shape.

11. The computer program product of claim 7 , wherein receiving the input destination includes receiving, by the system, a range of input destinations for the user, wherein the destination of the navigational route is a first destination of the range of input destinations, wherein the method further includes:
transmitting a second control signal to the reconfigurable display surface to cause the reconfigurable display surface to render a third 3D shape on the map for each destination of the range of input destinations other than the first destination, and rendering a polyline on the map, wherein the polyline connects each destination in the range of input destinations; and
changing the destination of the navigational route from the first destination to a second destination of the range of input destinations, wherein the second destination is selected in response to receiving a touch input by the user in which the user touches the first 3D shape for a period of time, wherein the reconfigurable display surface is configured to cycle, during the period of time, between destinations of the range of input destinations.

12. The computer program product of claim 7 , wherein the rendering of the navigational route further includes changing topography of the reconfigurable displa
