Interaction and Experience Design

Interaction and Experience Design is the multidisciplinary practice of shaping how people engage with digital and physical systems to meet their goals effectively, efficiently and enjoyably. At its core lies a human-centred process that combines insights from psychology, ergonomics, visual design and emerging technologies to create interfaces and interactions that feel intuitive and emotionally fulfilling. This field addresses the full spectrum of user perceptions—from initial awareness and navigation through tasks to lasting impressions of satisfaction and meaning. Its methodologies include participatory research, iterative prototyping and usability evaluation, which together ensure products adapt to diverse user backgrounds, contexts and modalities. Contemporary challenges range from optimising web-based visual layouts for educational and corporate audiences to crafting immersive experiences in augmented and virtual reality. By integrating multisensory cues, adaptive feedback and inclusive accessibility practices, Interaction and Experience Design delivers coherent journeys across platforms, promotes psychological well-being and fosters sustainable behaviour in both personal and societal domains.

Online art platforms designed according to principles of coherence, novelty, interactivity and immersion can function as restorative environments that enhance the psychological well-being and loyalty of young digital-native audiences. A structural-equation study reveals that perceived aesthetic restoration strengthens place attachment, suggesting that carefully crafted digital exhibitions support mental health by replicating the therapeutic qualities of physical art spaces. Eye-tracking and behaviour-data studies have shown that educational background significantly shapes attention to webpage visual elements. Corporate employees and undergraduates focus more on images and layouts, whereas social-welfare workers and postgraduate users pay less visual attention, indicating that designers must align visual hierarchies and spacing with users’ cultural and professional contexts. Wearable olfactory modules synchronised with AR and VR visual overlays can heighten immersion and recall in extended-reality applications. By delivering scent cues alongside spatial graphics, systems achieve faster task completion and stronger emotional engagement, demonstrating a new multisensory paradigm in which scent becomes an integral channel for extending user attention and memory retention.

In virtual reality, introducing dynamic optical-flow cues around users has been shown to extend the thresholds at which redirected-walking curvature becomes detectable, particularly for experienced users. This technique allows scene-curvature gains to remain unnoticed, enabling naturalistic locomotion in constrained spaces without disrupting presence, and guiding the calibration of redirect-gain limits. Studies of text entry in headset-based XR environments find that handwriting on physically aligned surfaces yields higher learnability and lower physical demand than mid-air writing, with sentence complexity selectively affecting speed and error rates. These insights inform the design of digital-ink recognition and controller styling to balance natural pen-and-paper skills with immersive interaction demands.

Interaction and Experience Design publication trend

The graph below shows the total number of articles in interaction and experience design across all publications each year (not limited to Nature Index journals).

Technical terms

Redirected walking: A VR locomotion technique that subtly warps the virtual scene around the user to enable natural walking within limited physical tracking boundaries.

Optical flow: The pattern of motion perceived on the retina or display screen as an observer moves, here used to reinforce vection and mask redirected-walking curvature.

Curvature gain: The ratio of virtual path curvature to real-world walking trajectory, controlling how much the physical path bends without the user noticing.

Visual hierarchy: The organisation of interface elements by visual prominence—size, colour, contrast and alignment—to guide users’ attention effectively.

Digital-ink handwriting: A text-entry method in virtual or augmented reality where users form characters as on paper surfaces, tracked by motion-capture or controller sensors.

Multisensory augmentation: The integration of multiple sensory feedback channels, such as olfactory or haptic cues, to enhance immersion and memory encoding in interactive systems.
