Orientation selective (Viewing Vector) Proximity Sensor

For a research paradigm I want to implement a proximity sensor that is activated when a subject is looking, facing its heading direction towards a certain object. I could only find the proximity sensor function for certain positions and not orientation.

So I would like something like this:

Code:

initialHeadingPole = viz.add('pole.wrl')

initialHeadingPoleSensor = vizproximity.Sensor(vizproximity.RectangleArea([3,2]), source=initialHeadingPole)



manager = vizproximity.Manager()

manager.setDebug(viz.ON)

#debugEventHandle = vizact.onkeydown('d',manager.setDebug,viz.TOGGLE)

#Add main viewpoint as proximity target

target = vizproximity.Target(viz.MainView)

manager.addSensor(initialHeadingPoleSensor)

Any help would be greatly appreciated!

Hi,

you don't need sensors to do that. I would rather use a timer to call a function every frame that constantly checks the view direction and sends a signal when a certain value is reached, e.g.:

Code:

import viz

import viztask





arena = viz.addChild('pit.osgb')



angleSignal = viztask.Signal()

checkedAngle = 90                # at which view angle should the sensor be activated?





def checkViewAngle():

        [yaw,picht,roll] = viz.MainView.getEuler()

        

        if int(yaw) == checkedAngle:

                angleSignal.send()

                print('Angle detected!')



orientationSensor = vizact.ontimer(0,checkViewAngle)        # start the function



viz.go()

hi,

thanks, exactly what i needed!
