Towards Smart Gaming Olfactory Displays

Area of Science:

• Human-Computer Interaction
• Sensory Feedback Systems
• Olfactory Technology

Background:

• Olfactory displays can enrich multimedia experiences but are often expensive, limited, and lack intelligent control.
• Current systems are typically experiment-specific, hindering broader application and modification.
• A significant gap exists in automated and adaptable scent delivery for interactive media.

Purpose of the Study:

• To propose and develop a low-cost, adaptable, and intelligent olfactory display system.
• To enable precise control over scent release quantity and timing.
• To integrate scent delivery with multimedia content, particularly gaming.

Main Methods:

• Development of a smart olfactory display with capacity for 24 aromas and aroma absorption.
• Implementation of a control algorithm for automated scent release decisions.
• Creation of a device controller application supporting timed, subtitle-based, and external software triggers.

Main Results:

• The developed olfactory display is low-cost, easy to build, and supports up to 24 aromas with quantity control.
• The system features aroma absorption for air purification between scent releases.
• User evaluation with 15 subjects demonstrated high accuracy in scent delivery timing (1.5-minute intervals).

Conclusions:

• The proposed smart olfactory display offers a powerful, cost-effective solution for integrating scent into digital experiences.
• The intelligent control algorithm and adaptable design overcome limitations of previous olfactory displays.
• This technology significantly enhances immersion in applications like virtual reality and gaming through synchronized scent delivery.
