Using Leap Motion in Virtual Reality assisted house design process

[pthor]

Hi,
I'm doing some prototyping with the Leap Motion in a house design process technology exploration phase. This Youtube clip illustrates a very basic sequence in where objects in a room can be moved around with quite precise accuracy.

Using Leap Motion in Baldakinen V0.5.2 Alpha

I hope you enjoy it, feel free to ask questions of any kind if anyone of you need help or guidance.

Hi Peter,

First of all congratulations for your work, it is amazing!
I'm new in Leap motion, and i have to replace the keyboard in a virtual reality environment (C++) in my MSc project.
I've linked the libraries "Leap.h, LeapMath.h and libleap.so" to my project, and i haven't had any problems, but i don't know how can be detected a finger, hand or any gesture to apply in my 2D Virtual project.

Could you help me?

Many thanks
Alberto

Alberto,
I am glad you enjoyed the demo, thank you for the appreciation.In the demo I have not used C++ but it is a Unity3D C# implementation. However I can give you some pointers.

I'd recommend you start reading this for an overview:
https://developer.leapmotion.com/documentation/cpp/devguide/Sample_Tutorial.html

Data from the Leap motion arrives through the so called Frame object. You can either get this data by polling or using a listener callback. I'd recommend that you start with simple polling if you haven't got knowledge about threads:
https://developer.leapmotion.com/documentation/cpp/devguide/Leap_Frames.html#getting-frames-by-polling

From this frame, you start parsing the hand data:
https://developer.leapmotion.com/documentation/cpp/devguide/Leap_Hand.html

I have not looked extensivly inside the C++ examples directory but there are some samples linked here:
https://developer.leapmotion.com/documentation/csharp/examples/CPP_Examples.html

and to render hand skeletons you could maybe look at the source of this demo:
https://developer.leapmotion.com/gallery/magnetic-mesh

I hope this can get you going in one direction or another,
Peter

Hi Peter,

Good work. I'm trying same as what you did I don't have much knowledge in this so can you please guide me....
I'm using Unreal Engine and LeapMotion connected with PC. I done walkthrough in BluePrint using LeapMotion but struggling to pick up the object and drop at desired position Kindly give some suggestion or any sample project.
I tried this and it works but not expected as what we expected. . .

Regards
Rasa

RasaMohamed,
I am sorry but I have not got experience with UE and Leap Motion so I can sadly not help you.

I hope you've solved your problems by now,
Peter
