Work was done on motion tracking and user interface. Motion tracking involves animating the placeholder shape, for the face images, so that they line up with the heads of the dancers in the videos. So, when the user uploads their picture, the videos have a smooth and comical animation. The interface lets you scroll through the different available videos on the app.
This is the image input screen, the user can upload their image here. You can add more images by pressing on a blank face or the ‘another elf’ button. On the right you finalize your selections and get to the video!
After the user uploads a photo they are then asked to line up the image so that it fits in the head shape.
