The interest in enhancing video game interactions through wearable technology has grown, yet accessible gaming with wearables remains underexplored. This study employs participatory design fiction, enabling disabled gamers to envision a future with tailored gaming wearables while critiquing technology. We conducted a two-phase study. Phase one involved in-depth interviews with upper limb motor disability participants; we developed a fictitious gaming wearable by analyzing the data using reflexive thematic analysis. A smaller group iterated on the wearable in phase two to ideate on ideal futures with accessible gaming wearables. Using data and dialogic/performance analysis, we crafted a design fiction diegetic prototype as a tech review video. This research highlights disabled gamers' unique needs and experiences around gaming wearables. It offers an innovative diegetic prototype for accessible gaming tech. Our methodological contribution merges narrative inquiry and dialogic/performance analysis in participatory design fiction research, providing a valuable approach for future studies.

We present Adaptic, a novel "hybrid" active/passive haptic device that can change shape to act as a proxy for a range of virtual objects in VR. We use Adaptic with haptic retargeting to redirect the user's hand to provide haptic feedback for several virtual objects in arm's reach using only a single prop. To evaluate the effectiveness of Adaptic with haptic retargeting, we conducted a within-subjects experiment employing a docking task to compare Adaptic to non-matching proxy objects (i.e., Styrofoam balls) and matching shape props. In our study, Adaptic sat on a desk in front of the user and changed shapes between grasps, to provide matching tactile feedback for various virtual objects placed in different virtual locations. Results indicate that the illusion was convincing: users felt they were manipulating several virtual objects in different virtual locations with a single Adaptic device. Docking performance (completion time and accuracy) with Adaptic was comparable to props without haptic retargeting.

Direct manipulation has been established as the main interaction paradigm for Computer-Aided Design (CAD) for decades. It provides fast, incremental, and reversible actions that allow for an iterative process on a visual representation of the result. Despite its numerous advantages, some users prefer a programming-based approach where they describe the 3D model they design with a specific programming language, such as OpenSCAD. It allows users to create complex structured geometries and facilitates abstraction. Unfortunately, most current knowledge about CAD practices only focuses on direct manipulation programs. In this study, we interviewed 20 programming-based CAD users to understand their motivations and challenges. Our findings reveal that this programming-oriented population presents difficulties in the design process in tasks such as 3D spatial understanding, validation and code debugging, creation of organic shapes, and code-view navigation.

Parametric Computer-aided design (CAD) enables the creation of reusable models by integrating variables into geometric properties, facilitating customization without a complete redesign. However, creating parametric designs in programming-based CAD presents significant challenges. Users define models in a code editor using a programming language, with the application generating a visual representation in a viewport. This process involves complex programming and arithmetic expressions to describe geometric properties, linking various object properties to create parametric designs. Unfortunately, these applications lack assistance, making the process unnecessarily demanding. We propose a solution that allows users to retrieve parametric expressions from the visual representation for reuse in the code, streamlining the design process. We demonstrated this concept through a proof-of-concept implemented in the programming-based CAD application, OpenSCAD, and conducted an experiment with 11 users. Our findings suggest that this solution could significantly reduce design errors, improve interactivity and engagement in the design process, and lower the entry barrier for newcomers by reducing the mathematical skills typically required in programming-based CAD applications

3D Computer-Aided Design (CAD) users need to overcome several obstacles to benefit from the flexibility of programmatic interface tools. Besides the barriers of any programming language, users face challenges inherent to 3D spatial interaction. Scripting simple operations, such as moving an element in 3D space, can be significantly more challenging than performing the same task using direct manipulation. We introduce the concept of bidirectional programming for Constructive Solid Geometry (CSG) CAD tools, informed by interviews we performed with programmatic interface users. We describe how users can navigate and edit the 3D model using direct manipulation in the view or code editing while the system ensures consistency between both spaces. We also detail a proof-of-concept implementation using a modified version of OpenSCAD.

Significant obstacles persist in meeting the accessibility needs of computer and smartphone users with mild-to-moderate upper limb motor impairments as they use their devices at work and home. Multimodal input can help, but has not been widely adopted. We build on existing literature with a discovery survey and semistructured follow-up interviews in which we identify common themes related to the limitations of today’s solutions and the ad hoc workarounds which are adopted. We ran a series of co-design workshop sessions to understand the potential of modern “physical computing” electronic device prototyping technologies to provide new and effective input options for our target user base. We present the resulting prototype solutions and describe the technology choices made. Finally, we discuss how the co-design process, in conjunction with access to suitable physical prototyping technologies, can be a powerful approach for designing accessibility-focused input systems.
