This study introduces a novel interaction model for 3D virtual worlds, translating natural walking gestures into virtual navigation. A "virtual bike" device facilitates intuitive movement, overcoming traditional interface limitations.

Area of Science:

Human-Computer Interaction
Virtual Reality
Computer Science

Background:

Virtual world navigation is often complex and inefficient, relying on artificial interfaces like buttons and key sequences.
Simple actions such as changing viewpoint can be challenging in current 3D environments.
Existing interaction metaphors can lead to unnatural and cumbersome user experiences.

Purpose of the Study:

To develop an intuitive interaction model for navigating three-dimensional virtual worlds.
To create a non-WIMP (Window, Icon, Menu, Pointer) interface that uses natural user gestures.
To enhance user immersion and efficiency in virtual environments.

Main Methods:

An interaction model was designed to interpret natural user gestures from real-world walking.

A prototype device, the "virtual bike," was developed to test the interaction model.

Users navigated a virtual environment using the "virtual bike" to mimic real-world biking.

Main Results:

The proposed model allows for natural gesture-based navigation in 3D virtual worlds.
The "virtual bike" enabled users to move through the virtual environment intuitively.
The system demonstrated a more natural and potentially efficient alternative to traditional interfaces.

Conclusions:

Natural gesture interpretation offers a promising approach to improve 3D virtual world navigation.
The "virtual bike" serves as an effective tool for demonstrating intuitive virtual environment interaction.
This non-WIMP interface model enhances user experience by aligning virtual actions with real-world movements.
