Calibration not working correctly.
Changed back to manual alignment/calibration. Accuracy is so-so, but I don't have time to improve it. Added many new textures need for the usability study tasks. I created for different tasks/scenarios for the users. 1. Text deformation - interaction points shown but can be removed by pushing in the display; conversely, they can be shown again by pulling the display surface. This is done for both tasks 1 and 2. The user must look at the respective point orthogonally, and judge the distortion correction in two cases: corrected/uncorrected. 2. Scene deformation - a texture with pillars, all else is the same as task 1. 3. A google map - single finger interaction with landmark to display more info or hide it(push/pull). Also use two hand interaction at this stage. 4. Dynamic volume slicing of an MRI brain scan with two different interaction methods. Two hand interaction(push/pull)
Added distortion state randomness for when the scenario starts.
