My problem seems fairly simple. I am a research student at a Lab, and this lab has developed a haptic 3d input device. Naturally I am to do something with this device and Unity. I have DLLs to use in C# (using PInvoke).
So would it be possible to use both the device as a pointing device (like a 3D mouse) and an haptic device (force feedback) if I was to buy the Pro version of Unity? Can you add your own input device into unity?

Here's a similar Question where I listed some sample code that might make it more clear: How to import Neurosky Mindset data into Unity
On second thought, that code might be misleading - Neurosky provides some boilerplate code in a C# file, that is required to call the .dll. If you are starting from scratch, you would have to write code to use the Plugin that looks something like this:
And you can download Unity Pro Trial. The trial version is only valid for 30 days, but if this is a short, one-time project, that might be enough to complete it.
Hi, sorry to budge in with another question relating to "using my own input device". I am using a 3D input device, which I believe is similar to haptic, posted by simaldeff. I have the DDL in the plugin folder. I was able to read the data from the input device using the DLL API.
I am now experiencing this problem. When I move the device, the data I read and displayed using Debug.Log, lagged by about 1 second. This is not good because whatever I want to animate in Unity cannot respond to me instantanteously. I have no idea what causes the lagging.
I wrote another program in C++ to read the data from the same DLL and display it. Interestingly, there is no lagging at all. Seem like the problem is interaction between Unity and the DLL.
I have been looking through the forum for anyone with similar problem and any advice and pointers will be deeply appreciated. Thanks.

... A follow on...
I also am trying to link in a haptic device... I have it running on Android through bluetooth and windows through c/c++/and c# dlls
I understand that I should be able to get this running no problem with windows, but what about android or iphone?
Will Unity allow my code to connect to a bluetooth device and send and recieve packets?
If not could I do it if the device has an IP address with udp/tcp?

I have been able to call a objective-c dll from C# scripts thanks to the info you provided. However, I wish to receive callbacks from my C++ dll. I thought of using a delegate to catch the callbacks as I have done before, but I get errors saying I'm trying to JIT compile my delegate. Is there a way to get callbacks from a dll in unity?
