Envisioning the Immersive Web

The immersive web is envisioned to be the product of synchronizing motion sensing technology and the web to create a space that facilitates social interaction, entertainment, information retrieval, learning, and e-commerce in an environment.

● Multi-Modal Sensory Input ○ Vision - Head Mounted Device○ Haptic - Motion Sensor○ Audio -

THE IMMERSIVE WEB

● Fidelity - how technology facilitates presence/immersion.

● Immersion - level of which a user feels connected to multi-modal sensory input.

● Presence - how “present” a user feels inside a virtual environment.

● Realism - the extent to which the virtual reality accurately represents the real environment it seeks to simulate.

THE IMMERSIVE USER EXPERIENCE

SteamVR

● Web based interface that presents web pages as tiles/cards.

● Fits user’s current mental model of the web

JanusVR

● Portal based interface presents each website as an individual world within the MultiVerse.

● Users are navigate through the environment in portals.

APPLICATION AREA

Cognitive Walkthrough

Users participated in a scenario in which they were asked to navigate to a website and retrieve specific information.

○ Conditions: SteamVR | JanusVR○ Tasks: Navigate, Retrieve

Information, Consume Media, Send Information

○ Metrics: Accuracy, Time, Non-Critical Errors, Critical Errors, Presence, Simulator Sickness

Heuristic Evaluation

Both applications were evaluated based on immersive user experience heuristics to detect possible design inadequacies

○ Heuristics: Core principles (learnable, understandable, habitual, memorable), tracking consistency, ease of detection, state & transitions, dynamic feedback, error recovery & prevention.

SUGGESTIONS FROM HEURISTIC EVALUATION

A productive iteration of the immersive web combines both methodologies and provides the orientation of web pages as tiles as well as portal for transport to different worlds in the MultiVerse.

● Standardization○ webVR

● Scalability ○ Transcend online & offline personas

● Adaptability ○ Mixed Reality

● True Haptic Feedback○ Sound Waves

● Photorealism○ True Immersion
