Integrated physical product-digital application systems support autistic children, but component collaboration and evidence generation remain underexamined. Following PRISMA 2020, six databases were searched (2015-2025); two reviewers screened studies involving autistic participants aged ≤ 18 years and appraised artifact and evaluation reporting using DSR-oriented appraisal. Of 7,245 records, 20 studies were included. Social interaction was the most common target, followed by emotional skills and attention. Studies were concentrated among school-aged children and in structured educational or clinical settings. Applications most frequently served as content or training hubs, followed by personalizers or decision engines; other roles were uncommon. DSR-oriented reporting adequacy was high in five studies, acceptable in four, and low in eleven. More complete evidence chains generally involved clearer component roles, stronger links between system functions and outcomes, and more transparent evaluation procedures. Research themes expanded over time but remained parallel and heterogeneous rather than forming a unified cumulative pathway. The findings suggest that progress may depend less on technological variety than on stable links among user requirements, system architecture, implementation conditions, and long-term outcome assessment. We propose an evidence-oriented heuristic framework covering deployment controllability, outcome verifiability and evaluation-chain complexity, which supports cumulative evidence generation for tangible-digital autism interventions.
Adjustable-volume sockets are an emerging technology in the prosthetics marketplace. Current methods of adjustment use predominately passive mechanisms. In the future, electronic actuation will be of interest. This advancement requires a seamless and intuitive user interface. Prosthesis users (n = 5), certified prosthetists (n = 5) and prosthetic students (n = 13) were introduced to four interface prototypes. Participants interacted with a testing suite that included an electronically adjustable-volume socket, fob prototype and software interface. Participant preferences and survey responses were recorded through documentation and video. Prosthesis users and certified prosthetists preferred a simple pear-shaped design with prominent buttons for tightening and loosening the socket. Four of five prosthesis users considered a physical fob more desirable than a phone app. Prosthetists suggested implementing versatile attachment of the fob by lanyard or keychain, mounting on the outside of the socket or placing in a pocket. Prosthesis users and prosthetists preferred interfaces that minimized barriers connecting to and controlling the adjustable-volume socket. Ease of use and reliability need to be preserved as additional enhancements are added. For example, remote patient monitoring data should be presented in a phone app, but direct control of the socket should remain separate with the fob.
