Hi there, I am Bruno, a Human-Computer Interaction (HCI) researcher. My research focuses on adaptable, novel interaction techniques. I identify and study specific human factors in multiple contexts to grasp modern challenges, build interactive systems as solutions, and evaluate their efficiency in supporting users. I apply user-centered concepts to build interactive tools that adapt to the user's preferences and needs, for augmenting their capacities to perform a set of complex tasks.
I am a research scientist (Inria Starting Faculty Position) at Inria in the Loki team in Lille. I formerly did a postdoc in the HCI lab at Saarland University and completed a Ph.D. in Computer Science focused on Human-Computer Interaction at Télécom Paris (formerly Télécom ParisTech).
Visual content must be labeled to facilitate navigation and retrieval, or provide ground truth data for supervised machine learning approaches. The efficiency of labeling techniques is crucial to produce numerous qualitative labels, but existing techniques remain sparsely evaluated. We systematically evaluate the efficiency of tagging and brows...

Annotating sport performances enables to quantitatively and qualitatively analyze them, and profile athletes to identify their strengths and weaknesses. We designed an annotation and analytical tool tailored to lead climbing analysis, developed with and for the French climbing federation. We leveraged user-centered design methods based on an ite...

Thumb-to-finger interactions leverage the thumb for precise, eyes-free input with high sensory bandwidth. While previous research explored gestures based on touch contact and finger movement on the skin, interactions leveraging depth such as pressure and hovering input are still under-investigated. MicroPress is a proof-of-concept device that ca...

TactJam is an end-to-end suite for creating and sharing low fidelity prototypes of on-body vibrotactile feedback. It enables designers to create, record and share vibrotactile patterns online. This opens up new ways of collaboratively designing vibrotactile patterns both in collocated as well as in remote settings. We evaluated TactJam in...

Effective haptic feedback in virtual reality (VR) is an essential element for creating convincing immersive experiences. Tools for designing vibrotactile feedback keep evolving but often require expert knowledge and rarely support direct manipulation to design feedback-action mappings within the VR environment. Weirding Haptics is a novel...

Today’s typical input device is fat, rigid and made of glass. However, advances in sensing technology and interaction design suggest thinking about input on other surface, including soft materials. While touching rigid and soft materials might feel similar, they clearly feel diferent when pressure is applied to them. Yet, to date, studies only i...

Sensing devices are everywhere, up to the point where we become unaware of their presence. Eyecam is a critical design prototype exploring the potential futures of sensing devices. Eyecam is a webcam shaped like a human eye. It can see, blink, look around and observe you. In this project, we present speculative design scenarios with Eyecam to em...

Side-Crossing Menus (SCM), is a gestural technique enabling large sets of gestures on a smartwatch. It relies on position-dependent gestures that build on bezel and crossing gestures to maximize the input capacity of small interactive surfaces. In contrast with conventional gestural techniques, SCM relies on broad and shallow menus that favor sm...

Markpad is an gestural interaction technique working on laptop's trackpads. It enables rapid gestural shortcuts to trigger a large variety of commands on a laptop to open applications, trigger keyboard shortcuts, open bookmarks on the web or the file explorer, and more. The strength of Markpad is to be user-tailored: users can customize their ge...

bARefoot is a vibrotactile shoe prototype with high-frequency sensing and vibrotactile actuation. It closely synchronizes vibration with user actions to create virtual materials. bARefoot can be used to deepen the sense of immersion in VR by, for example, allowing users to probe the strength of a thin ice layer. It can be used in AR for augmenti...

To memorize information efficiently, human beings created a large variety of mnemonic methods. One of the most powerful called the memory palace or method of loci, requires the mnemonist to picture a mental space, move through this place to visualize elements located in this space and recall them. With advances in mixed reality, it is now possib...

In traditional body-art, designs are adjusted to the body as they are applied, enabling creative improvisation and exploration. Conventional design and fabrication methods of epidermal interfaces, however, separate these steps. With BodyStylus we present the first computer-assisted approach for on-body design and fabrication of epidermal interfa...

Using microgestures, prior work has successfully enabled gestural interactions while holding objects. Yet, these existing methods are prone to false activations caused by natural finger movements while holding or manipulating the object. We address this issue with SoloFinger, a novel concept that allows design of microgestures that are robust ag...

Polysense is an open-source fabrication process for creating smart textiles. It builds on traditional manual crafts and a DIY approach to allow the broadest audience to create novel smart textile sensors. Using this method, anyone can augment a plethora of fabric and textile samples to rapidly create sensors than can be worn on the body. It does...

Skin is personal and sensitive. As a result, design and placement of on-body physical interfaces need to be well thought out. One way of “getting the design right” is to take an iterative design approach and sketch a multitude of designs to be modified, adjusted and elaborated on. Using piezo-resistive kinesiology tape made available through the...
