Research Background and Problem Statement

• Identified Issues or Challenges:

  • Digital games are often designed for a single type of player, lacking support for specific groups such as those with visual impairments.
  • Individuals with visual impairments are often limited to audio games and cannot participate in mainstream multiplayer games with sighted players, leading to community isolation.
  • Game design efforts to achieve accessibility often simplify the experience, which can result in unbalanced gameplay or a lack of engagement for players.

• Importance of the Problem:

  • Mixed-ability gaming scenarios are crucial for social inclusion and accessible design, as they help mitigate the limitations caused by ability differences, reduce barriers, and promote social integration.

• Research Motivation and Related Work:

  • Existing research on games for visually impaired players primarily focuses on single-player scenarios or retrofitting mainstream games, the latter of which involves significant modifications with limited effectiveness.
  • Drawing inspiration from asymmetric game mechanics (e.g., differences in roles, goals, or information) that enhance team collaboration and social connection, the authors propose a novel approach to incorporate ability-based asymmetry into mixed-ability games.

Proposed Solution

• Proposed Solution by the Authors:

  • The authors designed two cooperative game prototypes with asymmetric roles: Rescue: Under Pressure and Rescue: Mayday.
  • In each game, roles are divided into two complementary types: one focusing on visual tasks (e.g., map navigation and object manipulation) and the other on auditory tasks (e.g., environmental awareness and decision-making based on audio cues).
  • The interdependence between roles addresses the challenge of "collaboration limitations due to visual differences" while ensuring equality in role tasks.

• Innovative Aspects:

  • The study redefines the mixed-ability gaming experience by proposing that "inclusivity arises from designed asymmetry rather than mere equalization."
  • By integrating asymmetric mechanics and ability-based design, the games create an equal and challenging space for players with different abilities.

• Implementation Steps and Key Technologies:

  1. Game Design:
     • The games were designed using the three-layer model (mechanics, dynamics, aesthetics) to ensure tight integration of role interdependence and ability-based collaboration.
     • Key tasks were matched to player abilities, such as visual challenges (navigation, exploration) and auditory challenges (audio feedback analysis).
  2. Technical Implementation:
     • The games were developed using Unity, offering audio and keyboard accessibility options, along with interfaces specifically designed for visually impaired players.
  3. User Research:
     • Remote user studies were conducted to evaluate the impact of the games on players with mixed visual abilities, using quantitative questionnaires (UPEQ) and qualitative interviews.

Research Findings

• Key Findings:

  • Game testing revealed that the asymmetric role tasks designed for visual and auditory abilities did not make players feel limited by their abilities; instead, they fostered mutual appreciation of each other's strengths during collaboration.
  • The prototypes provided equal participation opportunities for mixed-ability players, enhancing social interaction.
  • Players showed strong interest in the challenges presented by the games, although some participants expressed a desire for more diverse game content.

• Advantages:

  • Compared to existing accessible games, this design effectively balances collaboration and contribution among players with different abilities.
  • The role tasks ensured fairness in task allocation while fostering strong interdependence, enhancing the sense of collaboration.

• Experimental or Evaluation Results:

  • Overall, players rated their experiences in both games highly, with Rescue: Under Pressure receiving slightly higher ratings than Rescue: Mayday.
  • Regardless of player group (visually impaired or sighted), participants reported high levels of engagement, autonomy, and competence.

• Limitations and Future Directions:

  • Limitations:
    • The game design is specifically tailored for mixed-ability scenarios and does not address the independent gaming needs of visually impaired users.
    • Both games are early prototypes, and their content and mechanics may not sustain long-term player engagement.
  • Future Directions:
    • Expand role task mechanisms to support more diverse interaction forms, such as multiplayer modes or non-mixed-ability scenarios.
    • Broaden the scope to consider other ability differences (e.g., auditory or motor impairments) to provide more inclusive designs.
