Inclusive gaming
We frame the act of playing games with others as a way to reinforce social bonds, reduce stigma, enhance social support and inclusion.
In this work, we introduce the Living Framework for Cooperative Games (LFCG), a framework derived from a multi-step systematic analysis of 129 cooperative games with contributions of eleven researchers. We describe how LFCG can be used as a tool for analyses and ideation, and as a shared language for describing a game’s design. LFCG is published as a web application to facilitate use and appropriation. It supports the creation, dissemination and aggregation of game reports and specifications; and enables stakeholders to extend and publish custom versions. Lastly, we discuss using a research-driven approach for formalising game structures and the advantages of community contributions for consolidation and reach.

Disparate skill levels or expertise may result in unbalanced multiplayer experiences, where players feel frustrated, unchallenged, or left out. Some games employ player balancing mechanisms, such as matchmaking to group players according to their rank or, in racing games, players who lag behind receiving powerful boosts to catch up. We add to the understanding of player balancing in multiplayer gaming. First with a theoretical model that captures seven high-level design categories. Second, with a study where participant pairs experienced and gave their perspectives on seven different balancing mechanics in a racing game. Our results outline the importance of preserving a sense of merit and agency, while avoiding an obtrusive effect on the gameplay.

For families, where abilities, motivations, and availability vary widely, opportunities for intergenerational play are limited. Designing games that cater to these differences remains an open challenge. In this paper, we first identify barriers related with time and expertise. Next, we propose asymmetric game design and asynchronous play to reconcile children's and adults' requirements; and interdependent gameplay mechanics to foster real-world interactions. Following this approach, we designed a testbed game and conducted a mixed-methods remote study with six pairs of adult-child family members. Our results showcase how asymmetric, asynchronous experiences can be leveraged to create novel gaming experiences that meet the requirements of family play. We discuss how interdependent progress can be designed to promote real-world interactions, creating pervasive conversational topics that permeate the family routine.

In this work, we analyze over 70 hours of YouTube videos, where blind content-creators play visual-centric games. We point out the various strategies employed by players to overcome barriers that permeate mainstream games. We reflect on ways to enable and improve blind players’ experience with these games, shedding light on the positive and negative consequences of apparently benign design choices. Our observations underline how game elements are appropriated for accessibility, the incidental consequences of audio design, and the trade-offs between accessibility, agency, and engagement.

We explore a set of techniques that augment or are even embedded in the game design to facilitate navigation and spatial awareness of virtual environments. We conducted a user study where seven blind participants faced a number of navigational tasks in a virtual environment with these techniques and shared their perspectives on the experience. We contribute with an exploration of a catalog of techniques used to facilitate the navigation of virtual spaces and a reflection of their impact on players' experience, highlighting avenues for future work in the field.

Social virtual environments are becoming more prevalent, replicating and sometimes replacing real-world interactions. Nowadays, such environments are not accessible and end up excluding blind people, due to their strong visual components. In this study, we designed and explored multiple navigation and feedback techniques assessing social acceptability, ease of use, and efficiency. We developed a virtual environment composed of six scenarios to analyze different navigation methods (Free Exploration, Teleport, Auto-Walk, and Co-Pilot) and awareness cues in group conversations (Audio Cues While In-Group Footsteps and In-Group Teleport), and conducted a user study with 8 blind and 8 sighted participants. Our results indicate that participants tend to privilege autonomy and room awareness over efficiency and navigation ease and disapprove of intrusive actions that may jeopardize privacy.

We explore the use of games to inconspicuously train gestures. We designed and developed a set of accessible games, enabling users to practice smartphone gestures. We evaluated the games with 8 blind users and conducted remote interviews. Our results show how purposeful accessible games could be important in the process of training and discovering smartphone gestures, as they offer a playful method of learning. This, in turn, increases autonomy and inclusion, as this process becomes easier and more engaging.

We explore ability-based asymmetric roles as a design approach to create engaging and challenging mixed-ability play. Our team designed and developed two collaborative testbed games exploring asymmetric interdependent roles. In a remote study with 13 mixed-visual-ability pairs we assessed how roles affected perceptions of engagement, competence, and autonomy, using a mixed-methods approach. The games provided an engaging and challenging experience, in which differences in visual ability were not limiting. Our results underline how experiences unequal by design can give rise to an equitable joint experience.

We share multiplayer gaming experiences of people with visual impairments collected from interviews with 10 adults and 10 minors, and 140 responses to an online survey. We include the perspectives of 17 sighted people who play with someone who has a visual impairment, collected in a second online survey. Our focus is on group play, particularly on the problems and opportunities that arise from mixed-visual-ability scenarios. These show that people with visual impairments are playing diverse games, but face limitations in playing with others who have different visual abilities.

We present audio puzzle games, an interactive way of playing with music by rebuilding a song, just like the original image jigsaw puzzle, broken into pieces which are by turn randomly shuffled. The audio mode design followed a participatory approach starting from a version similar to the visual one, but around music instead of images. We report on an evaluation with 13 blind people using the proposed game application with three different songs randomly distributed.

Sled Racing is a simple racing game, where each player controls a penguin sitting on a floater going down an ice track. Based on an existing open-source game, this prototype adds options to enable player balancing mechanics (also known as catch-up mechanics) which seek to bring players closer in performance. These mechanics include speed boosts, new obstacles, and other changes to the gameplay.
