Description of the thesis topic

Shape-changing user interfaces (UI) have emerged as a new way to interact with computers, using dynamic changes in a device's physical shape for input and output. The prototyping of shape-changing UI, let alone their development, is a consensual grand challenge in the Human-Computer Interaction (HCI) community [Alexander et al. 2018]. The objective of the PhD is to study programmable matter as a new way to implement shape-changing user interfaces. Programmable matter is defined here as a modular robot composed of a huge number of mm-scale, stand-alone, spherical and detachable robots that can rearrange themselves in the 3D space, allowing for as many shapes as play-doh.
The research hypothesis is that programmable matter can overcome the drawbacks of current implementations of shape-changing interfaces such as pneumatic actuation [Yao et al. 2013], rod-based displays [Robinson et al. 2016] and mechanical structures [Kim et al. 2018a]. These solutions do not allow the modularity or the porosity of the interface [Kim et al. 2018b]. On the contrary, programmable matter allows reaching these shapes. While previous work in HCI has introduced modular robotics, it has been limited to 2D display made of mobile robots moving on a table [Le Goc et al. 2016]. To reach the objective, the plan is to rely on a user-centered methodology, around two main tasks: interaction techniques and software architecture.

The PhD student will work on interaction techniques leveraging the modularity and/or porosity of the interface, and their development in distributed UIs.

Interaction techniques

At a high level of abstraction, the candidate will identify, through scenarios of the related studies on shape-changing interfaces, the new interaction possibilities enabled by dynamically reconfigurable interfaces (e.g., merging or breaking groups of physical modules). The proposed interaction techniques will be prototyped using a new UI architecture.

Software architecture

At a low level of abstraction, the goal is to layout the foundations of UI architectures suited for molecular shape-changing interfaces. The dispatch of users' events is currently centralized. The research approach, in close collaboration with roboticists, consists of first identifying and gathering the problems and constraints that would impact the development of applications using standard UI approach. These observations will then be used, to assess how drastically our current representation of application architecture has to change and to propose adequate solutions. Interaction techniques will serve to assess how these would impact UI architecture and inform the proposed solutions.

Work Context

The LIG lab is a joint research unit (of which the CNRS is one of the supervisors) located on the campus in Saint Martin d'Hères. Composed of 22 teams, the 450 researchers, professors and doctoral students of the LIG work on various research topics related to computer science.
The IIHM group is concerned with the design, implementation, and evaluation of interaction techniques that are effective, usable, and enjoyable. The group is present in the main Human-Computer Interaction conferences: CHI, UIST, AVI, Interact, EICS, etc. It has long-lasting connections to other research groups in France and abroad, and is well connected to the industry. IIHM is part of the LIG lab in Grenoble, Alps, France.
