Approach For Flex Pad

★ Approach to capture the deformable object

○ Capturing the pose and detailed deformation

of a deformable surface from depth data in

real-time

★ enables users to interact

★ highly flexible projected displays

★ interactive

★ real-time applications

FlexPad

FlexPad Setup

★ Kinect camera

★ Projector

★ Sheet of paper

★ Foam or acrylic

★ Removal of hands and fingers

★ Global deformation model

★ How global deformation model

FlexPad Implementation

★ Exploring and analyzing volumetric

data sets

★ Animating virtual paper characters

★ Slicing through time in videos

Applications

★ Folding and very steep bending angles

★ Makes a trade-off

★ Not suitable for:

○ very sharp bends

○ Particular folds

○ Stretchable materials

Limitations...

Feasibility of FlexPad Evaluation★ Tracking performance

★ User performance of Deformation

Result★ Tracking performs very adequately even in challenging

realistic tasks.

★ Users are capable of using highly flexible displays with ease

Future works…

★ Touch input on deformable displays

★ Active flexible displays

★ Smart materials: programmable stiffness and

stretchability
