View Full Version : Gps input for viewpoint location?

I guess this would be for outdoor augmented reality applications...
But would there be support in Vizard soon for usb / Bluetooth "mouse" type GPS devices?

This would be great to actually feed Gps co ordinates into a user location, so that objects could be rendered in proper scale in the virtual world if thier real world dimensions were known and input into the Vizard world.

Thus in an outdoor augmented reality scenario, you could scale in realtime a Virtual object, if the Geo location of it were known.

I.e. as you "approached" the virtual object, (while wearing an HMD and carrying a portable computer with usb GPS unit) the object would scale up in size, and scale down as you walked away from it. This would happen of course because your location is being fed by live GPS co-ordinates in realtime.

I guess im not the first to think of this, but it would be great to have GPS plugin to plot user location in the Vizard world.

the problem there simply is the gps resolution, accuracy and frequency.
if you name a specific device off-the-shelf device that you think should work,
we'd be happy to have a look at it.

in general, you can connect to pretty much anything you want in vizard thu the labjack device/driver (usb device with analog / digital inputs/outputs). a labjack costs some $99.

i always say that if I wanted to control my garage door and coffee machine remotely,
i could quite easily do this with vizard if i want ...

oh sorry, i just saw your link to the

we'll look at it. however, i'm pretty sure that specifically it's orientation resolution will not be good enough for outdoor augmented reality

Hi Mspusch!
No currently its just an idea I had :) ( not a completely original one)
The picture was only for example purpose. I dont actually want to use it at this time.

Im still a long way off from realizing such an apparatus. One thing i know though, I'll bet it has to be Vizard driven!

I guess an intermediatary solution is to 'live' with Gps being a few meters off, and use such a solution for long distance AR visualization only. not for real time positioning feedback

Regards!
