One wears the Project Arousal System HUD and the invisible avatar attachment (attaches to the mouth by default) labeled Project Arousal System v3.773. This part is three small cubes. Add the Project Arousal – Chest v3.821, Project Arousal – Lower Body – No Texture Layer v3.821, and activate all the gestures.
Gestures, these give you keyboard and chat controls for the arousal system. You will need them if you need to adjust the volume of the sounds. Once added you can press Ctrl-G to open the Gestures Panel. This will show you the chat commands and shortcut keys, basically F1 to F9.
The Chest v3.821 and Project Arousal – Lower Body – No Texture Layer v3.821 (both are for any brand of body) provide the touch system for Arousal. The idea is two people wearing Project Arousal can click on each other’s bodies and get a reaction. See the image for the actions.
These actions are slow to work. That may be because I am testing with myself and my alt that is using the guest HUD. I suspect the system is repeatedly searching for an avatar with PA. I think it uses a 5m radius. These actions are intended for two people both with the full Arousal system.
The PA System HUD is for controlling your arousal manually. Otherwise, it isn’t needed.
