Designing Interactions
& User Experience

As a UX designer and Human-Computer Interaction (HCI) reseacher, I focus on designing novel interactions in various contexts like laptops or mixed reality, and explore user experiences via usability tests conducted in the lab or on the field. Through my journey in academic research, I learned to grasp and adapt to new technologies, develop systematically interactive prototypes, and analyze thoroughly empirical data. I plan to bring these diverse skills from academic research to a broader context.


Weirding Haptics

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 concept that supports fast-prototyping by leveraging the user’s voice to design such feedback while manipulating virtual objects in-situ. To study our concept, we built a VR design tool that enables users to design tactile experiences using their vo...

Squish this

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 investigated force input on rigid surfaces. In this project, we investigated the effects of compliance on force input. For visual targeting tasks and three levels of softness, the results of a user study indicate that high force levels appear more dem...

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 emphasize the sensing capabilities of current sensing devices and how they can be insidious or deceitful. Eyecam was designed and built by Marc Teyssier whose work is famous for augmenting digital devices with hu...

Side-Crossing Menus

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 small and rapid gestures. The large gesture sets supported by SCM allow users to interact remotely with complex environments such as smart homes, large remote displays, or virtual reality environments, and switching between them (e.g., AR setup in a 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 gestures and map them to the actions they want. Markpad's gestures consist in simple strokes starting from the bezels of the trackpad, thus avoiding to conflict with common touch interactions without requiring extra delimiting actions (e.g. pressing a ...

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 augmenting existing materials with additional haptic cues, for example, to subtly indicate a desirable direction to walk towards or make running on artificial grounds more enjoyable. To enable experiencing a large variety of materials, we complement the desi...

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 possible to leverage the whole body for interacting. To provide an interaction technique facilitating the learning process, we propose to combine these two approaches. Hence, we propose BodyLoci, an interaction technique for mixed reality using the whole b...

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 interfaces. Inspired by traditional techniques, we propose a hand-held tool that augments freehand inking with digital support: projected in-situ guidance assists creating valid on-body circuits and aesthetic ornaments that align with the human bodyscape, w...

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 against movements that naturally occur during primary activities. Using a data-driven approach, we establish that single-finger movements are rare in everyday hand-object actions and infer a single-finger input technique resilient to false activation. ...

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 not require specific equipment, except simple kitchen tools. The PolySense project was born in DataPaulette under the direction of Cedric Honnet. ...

On-Body Sensors

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 Polysense process, one can sketch functional on-skin interfaces and experience innovative body interactions. For instance, one can design touch, gesture, and pressure sensors that way. We illustrate sketching techni...

Many gestural shortcuts exist to select rapidly a set of frequent commands on touch-sensitive mobile devices. The most commonly used are pointing gestures, however, research showed promising alternatives building on directional gestures. This type of gestures is mostly used in pie menus. For these shortcuts to be efficient, they must be easy to memorize on the long term. To know which shortcut is the most efficient memorization-wise, we ran a study on two days. Our results did not yield evidence of a difference in terms of recall rate, but...
