1. Mixing the Real and the Virtual in a Hospital through Telepresence
Kevin Smith

2. Mixing the Real and the Virtual!
Can we mix virtual people with real people?
Can we mix real people with virtual people?

3. It has already been done!

4. Simulation & Training using Telepresence
Benefits:
Clinicians and other professionals with heavy demands on their time can participate in a simulation from anywhere in the hospital (or outside it)
Training can take place anywhere eg a simulation can be run in a patient’s room immediately after a real patient is discharged from that room

5. Is it possible? Light Field capture and display
Perceptually the same as an optical wavefront
Based on Integral Photography invented by Lippmann in 1908!
Acoustic Wave Field capture and generation

6. What’s a Lightfield?

7. Stanford Multi-Camera Array

8. Data Rate 128 cameras each operating at 30 fps 640 x 480 8 bit pixels
Total data rate of over 9 Gbps

9. Holografika’s HoloVizio

10. QinetiQ’s Autostereo 3D Display Wall

11. Everyone can see the same point

12. Autostereoscopic Displays Available Today
QinetiQ
Holografika
Deep Light

13. MIT LOUD

14. Data Rate 1020 microphones each sampling at 16 KHz 24 bits per sample
Total data rate of 393 Mbps

15. IOSONO: Wavefield Generation
Large array of speakers – uses Huygens’ Principle

18. MERL: 3D TV Lightfield capture and display 16 cameras at 30 fps
1300 x 1030 pixels, 24 bits
Total data rate is over 14 Gbps

19. Technology Requirements
At least Tbps data connections as standard!
At least 100 fold increase in embedded computing power

23. Telepresence in a Hospital
Already being used eg
CSIRO’s ViCCU
InTouch’s RP-7 System

24. Telepresence in a Hospital
In the future, hospitals can be built where all walls are two way lightfields so that a person or an object can be projected in “full” 3D into any room of a hospital and, conversely, any patient can be imaged and viewed in “full” 3D

25. Examples of the Operational Use of Telepresence in a Hospital
Specialists can attend a “code blue” as well as the crash team
Nursing staff can respond through telepresence to a patient’s “call button” and assess whether have to go physically
A patient can be triaged in an ambulance by a trauma specialist
