“…The subject’s body was represented by either a male or female avatar to improve immersion ( Slater, 2009 ). The representation of the walking frame, followed the hybrid prototyping approach ( Exner et al, 2016 ). It was physically present and touched by the subjects, as well as also equipped with a tracker and visually represented in the VR.…”

Older pedestrians are at a high risk of becoming victims of car accidents because they tend not to pay sufficient attention to upcoming traffic. Within our research project, an assistance system for older pedestrians has been developed. It detects the street and communicates with the users through a vibrotactile interface. Two evaluation studies have been carried out in order to understand the potential benefits and drawbacks of the developed assistance system. One study was conducted in a virtual environment (VR) with 23 participants, aged 65+. The other experiment was a field test in a real street environment with 26 participants, aged 65+. Objective dependent variables in both experiments were checking for traffic (operationalized via head tracking) and stopping in front of the street (VR study), i.e., approaching time (field test). Workload and acceptance served as subjective dependent variables. Analysis of the VR experiment showed significantly more head rotation with the assistance system than without it, as well as significantly more with cars than without cars. The same was true for the frequency of stopping. No significant difference was found concerning workload. With regard to acceptance, the majority of participants indicated that the system was supportive and able to reduce risks in traffic. In the field test, results for head rotation confirmed the findings of the VR study. Analysis showed a marginally significant higher head rotation frequency with the alarm system than without, and significantly different patterns of checking for traffic at marked and unmarked crossings. However, unlike in the VR study, no differences were found in approaching time with and without the assistance system. Approaching time was slower at marked crossings. No difference was found with regard to workload, meaning the use of the assistance system did not increase the subjectively perceived workload of participants. Analysis of the acceptance questionnaire showed a positive attachment to the assistance system. However, most reported that they did not experience any advantage from the use of the system, and expressed no intention to buy such a system for themselves.

“…material) and approaches (type of prototype / way in which it is used) are better suited to different purposes, roles, activities, etc., due to their inherent properties. For example, (Bähr and Möller, 2016;Exner et al, 2016;Liker and Pereira, 2018) all discuss the benefits of virtual or mixed prototyping (combined physical/virtual) over purely physical, including increased flexibility, higher fidelity, and increased potential for automated or advanced analysis. Similarly, Pei (2011) discusses utility across four levels of Visual Design Representation (sketch, drawing, prototype, model making), Stowe (2008) across levels of system scope (amongst several delineations), and Camburn (2017) across many forms of prototyping media in an excellent review of prototyping state of the art.…”

Still others have claimed alignment between media and forms of learning (Real et al, 2021), levels of stakeholder accessibility (Isa and Liem, 2014;Verlinden and Horváth, 2009), support of collaboration (Bähr and Möller, 2016;Exner et al, 2016;Verlinden and Horváth, 2009), and model management (Tseng et al, 1997;Zorriassatine et al, 2003). However, while such directionality between the inherent properties of prototyping media and their utility for different design activities is widely accepted, there is to date no clear framing or overview of such properties as a set that would then enable fair comparison between media and approaches.…”

“…Interactivity: Different media provide the potential for different modes of interaction, which in turn enable different forms of learning for the designer (Bähr and Möller, 2016) and across different stakeholder groups (Ahmed and Demirel, 2020). Enabling high fidelity interactions at earlier stages of design through (e.g., mixed reality prototypes) brings forward important design decisions (Exner et al, 2016;Kent et al, 2021a), while the tangibility and realism of physical prototypes gives interactive freedom, but often a more limited range of possible interaction types than virtual (Isa and Liem, 2014).…”

How Should We Prototype? Establishing the Affordances of Prototyping Media and Approaches

et al. 2023

The breadth of media and approaches used when prototyping are vast, with each holding inherent properties that vary their suitability for a given prototyping activity.While several have established classifications of types and purposes of prototypes, there is little by way of guidance for designers on how select and strategise prototyping given their activity needs, or how the prototype chosen may influence their process, success or efficiency.This paper presents nine affordances of prototypes derived from literature, together characterising the properties of prototyping media or approaches that affect their suitability across prototyping activities.The affordances are illustrated through application to physical and digital classes of prototypes and four real prototype cases, showing descriptive capability, inherent differences between the media, and enabling direct and consistent comparison.By mapping affordances across many media and approaches, this work enables better method selection to align with activity needs, better description and comparison of media and approaches, and the ability the broadly interrogate and direct future development of prototyping technologies.
