Hinge Gestures: Leveraging Foldable Phone Hinges to Enrich Dual-Screen Tactile Interaction

Foldable phones naturally support displaying two applications side by side on adjacent screens. However, one-handed interaction with this dual-screen configuration faces two challenges: first, users must change grip to reach each screen; second, menus displayed on each screen take valuable screen real estate and can b…

Grip-Reach-Touch-Repeat: A Refined Model of Grasp to Encompass One-Handed Interaction with Arbitrary Form Factor Devices

We extend grasp models to encompass one-handed interaction with arbitrary shaped touchscreen devices. Current models focus on how objects are stably held by external forces. However, with touchscreen devices, we postulate that users do a trade-off between holding securely and exploring interactively. To verify this, w…

User-Driven Constraints for Layout Optimisation in Augmented Reality

Automatic layout optimisation allows users to arrange augmented reality content in the real-world environment without the need for tedious manual interactions. This optimisation is often based on modelling the intended content placement as constraints, defined as cost functions. Then, applying a cost minimization algo…

3D Printed Interactive Multi-Storey Model for People with Visual Impairments: Co-Design Process and Comparative Study between a 3D Model and 2D Tactile Maps

The understanding of multi-level spatial topologies is a difficult and frequent challenge in people with visual impairments daily life, impacting their independent mobility. Using the tools of the “maker” movement, and following an iterative co-design process with Orientation and Mobility instructors, we created an i…

Mold-It: Understanding how Physical Shapes affect Interaction with Handheld Freeform Devices

Advanced technologies are increasingly enabling the creation of interactive devices with non-rectangular form-factors but it is currently unclear what alternative form-factors are desirable for end users. We contribute an understanding of the interplay between the rationale for the form factors of such devices and the…

HoloBar: Rapid Command Execution for Head-Worn AR Exploiting Around the Field-of-View Interaction

Inefficient menu interfaces lead to system and application commands being tedious to execute in Immersive Environments. HoloBar is a novel approach to ease the interaction with multi-level menus in immersive environments: with HoloBar, the hierarchical menu splits between the field of view (FoV) of the Head Mounted Di…

KeyTch: Combining the Keyboard with a Touchscreen for Rapid Command Selection on Toolbars

In this paper, we address the challenge of reducing mouse pointer transitions from the working object (e.g. text document) to simple or multi-level toolbars on desktop computers. To this end, we introduce KeyTch (pronounced ‘Keetch’), a novel approach for command selection on toolbars based on the combined use of the…

Tactile Fixations: A Behavioral Marker on How People with Visual Impairments Explore Raised-line Graphics

Raised-line graphics are tactile documents made for people with visual impairments (VI). Their exploration relies on a complex two-handed behavior. To better understand the cognitive processes underlying this exploration, we proposed a new method based on “tactile fixations”. A tactile fixation occurs when a finger is…

Grand Challenges in Immersive Analytics

Immersive Analytics is a quickly evolving field that unites several areas such as visualisation, immersive environments, and human-computer interaction to support human data analysis with emerging technologies. This research has thrived over the past years with multiple workshops, seminars, and a growing body of publi…
