Usability Evaluation Methods for Gesture-Based Games: A Systematic Review

Area of Science:

• Human-Computer Interaction
• Game Design
• Usability Engineering

Background:

• Gestural interaction systems are increasingly integrated into games for entertainment and health benefits.
• Evaluating the usability of these gesture-based interfaces is crucial for balancing functionality and user-friendliness.
• Motion-sensing devices expand the possibilities for immersive and interactive experiences.

Approach:

• A systematic review was conducted on 1427 studies from major electronic databases (IEEE, ACM, Springer, Science Direct).
• Ten studies met the eligibility criteria, focusing on gesture-based games, motion-sensing devices (Kinect, Wii), and usability evaluation methods.
• Data extraction centered on usability methods employed, interface issues encountered, and strategies for developing effective gesture-based games.

Key Points:

• No standardized usability evaluation methods were found across the reviewed studies, with diverse analysis variables and instruments used.
• Questionnaires were the most common evaluation instrument (70%), followed by interviews (30%) and observation/video recording (20%).
• A significant portion (60%) of studies utilized gesture-based serious games for evaluating elderly participants in rehabilitation, indicating a specific need for tailored protocols.

Conclusions:

• The field requires a standardized usability evaluation method for serious games, particularly those designed for older adults.
• Developing a specific methodology and test protocol can enhance user comfort, welfare, and confidence in gesture-based gaming interfaces.
• Addressing age-specific needs and limitations is essential for creating truly user-friendly interfaces for diverse populations.
