Internship: External projection to add display capabilities to shape-changing interactive objects

Shape-changing interfaces (SCI) are tangible interfaces able to change their physical shape to support input, output or both [Alexander et al. 2018]. Past research on SCI has focused on enabling technologies to control the deformation of physical objects. However, a graphical feedback is a very common and high troughput channel of many forms of Human-Computer Interaction (HCI). Current SCI offer too limited, too little robust, graphical feedback for in-depth user experiments [Alexander et al. 2018]. The goal of the project is to study the feasability and the performance of simulating high definition graphical feedback on deformable object by using an external video projector.

Using external projection to change the appearance of physical objects has been studied in the context of Spatial Augmented Reality [Bimber et al. 2019]. Projection can be used on tracked moving objects to create a container illusion [Berard et al. 2017]. However, the projection of high resolution graphical feeback on moving deformable objects is a more challenging problem.

The student will study the state of the art about augmenting deformable object with external projection. She will design an approach that is as generic as possible to allow external projection on objects of various shapes and having various type of deformations. She will protype a system to augment at least two types of objects, e.g. :
1. A bendable and/or extensible surface [Khalilbeigi et al. 2011, Ortega and Goguey 2019, Sarkis et al. 2019],
2. A soft deformable objects based on structured elastomer [Siéfert et al. 2019]

The student will then evaluate the prototype.


The internship requires making (e.g., 3D printing), coding (C++, 3D graphics) and statistics skills. If you feel unsure about your skills but are interested in the topic, contact us.
