3D Environment Walkthrough Testing

I have tested a walkthrough in my not-yet-finished 3d island environment using first person controller. The rotation of the view is controlled using mouse while the forward, back, left, and right walking movement is controlled using keyboard up, down, left, and right arrow. So basically, the function of the Wii Balance Board is the same as the keyboard. Only the difference is, the 3d environment is controlled based on our real-time foot movement. As for the view rotation, I'm thinking of using Wii Remote Controller to control it. The video below (excused the low graphics 3d quality shown by the video as it is to avoid slow laptop performance during recording) shows the environment walkthrough testing using keyboard and mouse.
