Augmented reality panorama supporting visually impaired individuals
View Patent ↗There is presented a system and method for providing real-time object recognition to a remote user. The system comprises a portable communication device including a camera, at least one client-server host device remote from and accessible by the portable communication device over a network, and a recognition database accessible by the client-server host device or devices. A recognition application residing on the client-server host device or devices is capable of utilizing the recognition database to provide real-time object recognition of visual imagery captured using the portable communication device to the remote user of the portable communication device. In one embodiment, a sighted assistant shares an augmented reality panorama with a visually impaired user of the portable communication device where the panorama is constructed from sensor data from the device.
1. An augmented reality engine comprising:
a remote device interface configured to receive ambient sensor data from a remote mobile sensing device over a network, the ambient sensor data reflecting a remote environment of a visually impaired person and including a current field of view and device position data;
a panoramic engine configured to construct an augmented reality panorama representing a 3D digital model of the remote environment and including some of its objects at least partially based on the ambient sensor data with the current field of view integrated into the augmented reality panorama 3D digital model as a function of the device position; and
a sighted assistant interface configured to:
present visually the 3D digital model of the augmented reality panorama along with the integrated current field of view to a sighted assistant,
generate device commands based on an interaction between the sighted assistant with at least one object in the 3D digital model and outside the current field of view,
transmit, via the remote device interface, the device commands to the remote mobile sensing device, the device commands instructing the mobile sensing device to capture additional object data associated with the objects in the augmented reality panorama outside the integrated current field of view, and
update the augmented reality panorama by incorporating the additional object data into the 3D digital model.
2. The engine of claim 1 , wherein the current field of view comprises image data captured by the remote sensing device.
3. The engine of claim 1 , wherein the augmented reality panorama comprises multi-modal panoramic data.
4. The engine of claim 3 , where the multi-modal panoramic data includes haptic data and where the device commands comprises haptic feedback instructions associated with real-world objects in the remote environment proximate to the visually impaired person and that correspond to the objects in the augmented reality panorama.
5. The engine of claim 1 , wherein the mobile sensing device comprises a smart phone.
6. The engine of claim 1 , augmented reality panorama comprises a personalized panorama associated with the visually impaired person.
7. The engine of claim 6 , the personalized panorama comprises private ambient sensor data under management of the visually impaired person.
8. The engine of claim 7 , wherein the personalized panorama comprises filtered portions as a function of the private ambient sensor data.
9. The engine of claim 1 , wherein the augmented reality panorama comprises historical portions representative of historical ambient sensor data.
10. The engine of claim 9 , wherein the augmented reality panorama comprises highlighted objects indicating differences between the historical portions and recently updated portions of the augmented reality panorama based on the current field of view.
11. The engine of claim 1 , wherein the augmented reality panorama comprises public portions representative of publicly gathered sensor data.
12. The engine of claim 1 , wherein the sighted assistant interface is further configured to present a latency indicating a time difference between acquisition of the ambient sensor data and presentation of the current field of view.
13. The engine of claim 1 , wherein sighted assistant interface is further configured to correct placement of the current field of view in the augmented reality panorama based on at least two of the following ambient sensor data: GPS location data, image registration data, accelerometer data, magnetometer data, wireless signal data, odometry data, and audio data.
14. The engine of claim 1 , wherein the augmented reality panorama comprises metatags assigned to the objects within the augmented reality panorama.
15. The engine of claim 14 , where wherein the metatags comprise metadata visible to the sighted assistant and superimposed on the augmented reality panorama.
16. The engine of claim 14 , wherein the metatags comprises non-visual metadata.
17. The engine of claim 1 , wherein the sighted assistant interface is further configured to indicate distances to the objects relative to the current field of view.
18. The engine of claim 1 , wherein the device commands comprise instructions to the mobile sensing device to activate an actuator indicating an object's position relative to the mobile sensing device.
19. The engine of claim 1 , wherein the device commands comprise includes instructions to the mobile sensing device to emit audible signals indicating an object's position relative to the mobile sensing device.
20. The engine of claim 1 , wherein the panoramic engine comprises an object feature registration module configured to convert the ambient sensor data into object landmarks within the augmented reality panorama.
21. The engine of claim 20 , wherein the object landmarks within the augmented reality panorama include image registration landmarks.
22. The engine of claim 21 , wherein the image registration landmarks comprise Scale-Invariant Feature Transformation (SIFT) landmarks.
