“…In this paper, we have necessarily focused on how the field of prosthetics has and can inform work in HCI, but we have largely ignored how HCI can inform and play a role in prosthetics research and practice. From improved prosthetics training [152] to empowering amputees to create their own assistive tools [73], to a better understanding of how people value their prosthetic devices [19], the breadth of HCI research has already made an important impact and still has much to offer the field of prosthetics. We believe these two fields offer an ideal area for continued cross-fertilization that we have only begun to explore.…”

Electromyography (EMG) has been explored as an HCI input modality following a long history of success for prosthesis control. While EMG has the potential to address a range of hands-free interaction needs, it has yet to be widely accepted outside of prosthetics due to a perceived lack of robustness and intuitiveness. To understand how EMG input systems can be better designed, we sampled the ACM digital library to identify limitations in the approaches taken. Leveraging these works in combination with our research group's extensive interdisciplinary experience in this field, four themes emerged (1) interaction design, (2) model design, (3) system evaluation, and (4) reproducibility. Using these themes, we provide a step-by-step framework for designing EMG-based input systems to strengthen the foundation on which EMG-based interactions are built. Additionally, we provide a call-to-action for researchers to unlock the hidden potential of EMG as a widely applicable and highly usable input modality.

“…3D printing technology became widely available in the second decade of the 21st century and empowered accessibility communities to create Do-It-Yourself (DIY) assistive technologies (Hurst and Tobias, 2011). Accessibility communities have been widely successful in designing DIY artefacts with a wide variety of prototypes, including upper limb prosthetics (Hofmann et al, 2016), customised thumb splints (Hofmann et al, 2019), wheelchair transfer boards (Hofmann et al, 2019), and tactile 3D printed objects to support special education for visually impaired (Buehler et al, 2014).…”

“…Its applications are not only confined to rapid prototyping, and printing tool parts and aesthetic models. The accessibility community has started to use democratized manufacturing to make society more inclusive for people with disabilities [Baldwin et al 2017;Banovic et al 2013;Hofmann et al 2016b;Hofmann 2015]. The Enable community [The Future 2018] uses 3D printing to print custom prosthesis.…”

Desktop-manufacturing techniques like 3D printing are increasingly popular because they reduce the cost and complexity of producing customized objects on demand. Unfortunately, the vibrant communities of early adopters, often referred to as łmakers,ž are not well-served by currently available software pipelines. Users today must compose idiosyncratic sequences of tools which are typically superposed variants of proprietary software originally designed for expert specialists. This paper proposes fundamental programming-languages techniques to bring improved rigor, reduced complexity, and new functionality to the computer-aided design (CAD) software pipeline for applications like 3D-printing. Compositionality, denotational semantics, compiler correctness, and program synthesis all play key roles in our approach, starting from the perspective that solid geometry is a programming language. Specifically, we define a purely functional language for CAD called λCAD and a polygon surface-mesh intermediate representation. We then define denotational semantics of both languages to 3D solids and a compiler from CAD to mesh accompanied by a proof of semantics preservation. We illustrate the utility of this foundation by developing a novel synthesis algorithm based on evaluation contexts to łreverse compilež difficult-to-edit meshes downloaded from online maker communities back to more-editable CAD programs. All our prototypes have been implemented in OCaml to enable further exploration of functional programming for desktop manufacturing.
