   "title": "Modular Tangible User Interfaces: Impact of Module Shape and Bonding Strength on Interaction",
   "url": "https://hal.science/hal-03884342",
   "abstract": "Modular Tangible User Interfaces (TUIs) - i.e., UIs made of small-scale physical modules-offer novel opportunities for tangible interaction thanks to their highly customizable form factor. Such modular TUIs were proposed with different shape of modules and bonding strength between them. The problem we address in this paper is the lack of knowledge of how bonding strength and shape of the modules impact usability. We present the first study exploring the impact of bonding strength and module shape on subjective user ratings when interacting with a magnetic modular prototype. We assessed three levels of bonding strength (low, mid, high) and two shapes (cubes and rounded cubes) in a controlled user study. Participants performed eight common manipulations found in the literature for (non-)modular TUIs. Experimental results showed that (1) cubic modules are overall easier and more satisfying to manipulate, except for precision and bending tasks, (2) low strength impairs UI solidity, but high strength impairs precision tasks with cubic modules.",

   "abstract": "The Computer Science Technical Bachelor degree in France aims at training professionals who participate in the design, production and implementation of computing solutions corresponding to users’ needs. Its program contains realistic situations where knowledge from several disciplines must be put in practice within the context of transversal student projects. This paper focuses on knowledge related to Human-Computer Interaction (HCI) and its interrelationship with other courses. It presents how the Grenoble and Valenciennes Technical Institutes manage the multidisciplinarity and discusses some lessons learnt from these experiences.",

   "title": "Molecular implementation of shape-changing user interfaces",
   "url": "https://theses.hal.science/tel-04378955",
   "abstract": "Shape-changing user interfaces (UIs), which refer to physical devices capable of altering their form to accommodate users, tasks, or environments, have the potential to bridge the gap between tangible user interfaces' physicality and the flexibility of graphical user interfaces. These UIs offer promising prospects, including adaptive affordances and improved eye-free interaction. However, due to their limited presence in everyday life, they introduce new considerations for the HCI community to examine, as previous research has highlighted the associated challenges.This thesis specifically investigates the challenges related to modular shape-changing interfaces. A crucial initial step involves isolating the design factors and comprehending their relative impact on user interaction. Our objective is to explore the challenges and opportunities presented by modular robots as a novel approach to implementing modular shape-changing UIs. In this context, modular robots are defined as ensembles of robotic modules, which are microelectromechanical systems embedding computational capabilities and enabling shape changes either independently or collectively.The research hypothesis is that modular robots can address the limitations of current implementations of shape-changing UIs, such as pneumatic actuation,  rod-based displays, and mechanical structures. Unlike these solutions, modular robots enable the addition of modules to an existing shape and facilitate the attainment of any desired shape, akin to programmable play-doh. This thesis contributes to the field of HCI by: (1) reviewing and structuring the design space of modular shape-changing UIs and (2) conducting user studies to evaluate the impact of three parameters—module size, shape, and strength—on the design of physical interfaces.",

   "title": "Impact of the Size of Modules on Target Acquisition and Pursuit for Future Modular Shape-changing Physical User Interfaces",
   "url": "https://hal.archives-ouvertes.fr/hal-03325220",
   "abstract": "Shape-changing User Interfaces (UIs) explore the ability of a UI to change its physical shape to support multiple interaction modalities for users’ input and/or system’s output. An approach currently studied to implement such interfaces at a high resolution is based on mm-sized, round, and self-actuated modules. The problem we tackle in this paper is to find the range of usable sizes of such modules, to better inform the trade-off between usability and technological feasibility. We assessed four sliders in a controlled user study: a standard slider and three sliders made of mock-up rounded modules of ø1 mm, ø2.5 mm, and ø5 mm. Experimental results show that (1) ø5 mm modules significantly impair performance for the pursuit task and subjective perception for both tasks, (2) performance increases when the size of modules decreases, but (3) users reportedly enjoyed the haptic feedback provided by ø1 mm to ø2.5 mm modules. These results provide deeper understanding on the impact of the size of modules on performance and subjective perception to inform current technological development of physical user interfaces made of small robotic modules.",

   "title": "Molecular HCI: Structuring the Cross-disciplinary Space of Modular Shape-changing User Interfaces",
   "url": "https://hal.archives-ouvertes.fr/hal-03215058",
   "abstract": "Shape-changing User Interfaces attract growing interest in Human-Computer Interaction. Modular robotics offer a great opportunity for their implementation. However, the current theoretical and technical advances of modular robotics are fragmented and little centered on the user. To unify existing work and center future research on the user, we perform a systematic literature review enabling us to build a unifying space for the design of modular shape-changing user interfaces. Our aim is to bridge the gap between HCI and robotics. Towards this aim, we conduct a thorough cross-disciplinary survey to propose: 1) a set of design properties at the scale of the interface (macro-scale) and at the scale of the modules (micro-scale) and 2) the impact of these properties on each other. We relate properties of different domains and identify inconsistencies to structure the design space. This paper can be used to describe and compare existing modular shape-changing UIs and generate new design ideas by building upon knowledge from robotics and HCI.",
