MR Application Development Two versions were developed; 1. Augmented Virtuality version 2. Virtual Reality version

Skills Required 3D designing Programming Domain knowledge on hardware Domain knowledge on platforms software development best practices Algorithms and optimization

Evaluation Resource usage on the device Accuracy of visualization User experience

Conclusion Presents a MR application development framework Proper visualization and interaction increases the usability Smartphone can run a MR application Object scanning using Kinect is successful Low GPS sensitivity is a constraint MR can be used to gain more benefits in different fields
