Tie-Fighter online

[Alex37]

Hi,

I'm trying to use 'the force' online with the tie-fighter application. I've added the acquisition client, launched the server and found my calibration values for the crop and simple DSP box : the beta power rebound after a movement is quite good.
However, when I launch the 'openvibe vr-demo tie-fighter', the ship is staying on the start screen with 'Ready ?' and does not begin following the beta power.
When I use it with the offline version, this is working.

Could you please help me? I would like to test this application in my lab for the christmas dinner animation.

Thanks,

Alexandra

the spaceship starts moving when it receives the corresponding "start" stimulation from the openvibe scenario. So you have to make sure that:
1) the lua stimulator box is connected in some way to the button VRPN server box
2) you start the openvibe scenario immediately after launching the VR application, so as to be sure the starting stimulation is well received by the VR application (this stim is just sent once, as the beginning of the scenario)

I hope it helps!

Best
Fabien

Hi Fabien,

Thanks for your fast answer.
You right, my problem came from the connection to the 'Button VRPN server' box.
It works online adding the same GDF file to get only the stimulations, so that's my stimulation's file that is corrupted. I'll try to improve it !

Best regards
Alexandra

Hi

I wanted to know how can the tie-fighter scenario be used online? I tried connecting the acquisition client, but am still unable to run the scenario online. I am using OpenVibe 0.15 and the tie-fighter-freetime scenario provided with it. When I run openvibe-vr-demo-tie-fighter executable, after starting the acquisition client and the scenario, the window for the game pops up and "READY?" is displayed, however there is no further progress.

The console log is as follows:

I wish to know what configurations are required to run the scenario online? I am using the BrainVision ActiChamp amplifier?

[jtlindgren]

Hi Sumitsoman,

tie-fighter-freetime.xml scenario appears to be constructed to read data from a file. To use it online, I suppose you'd need to modify the scenario to read data from the acquisition server ('Acquisition Client' box) and make the data from it match what the scenario expects (i.e. similar as the data in the default file).


Happy hacking,
