The Utilisation of LEGO and Other Materials as Prototyping Tools in the Co-Creation Process
This paper aims to investigate the usefulness of LEGO and other materials as prototyping tools in the co-creation process involving multiple stakeholders. The results demonstrate that using LEGO and other materials as prototypes in the co-creation process helps designers and stakeholders to explore, evaluate and modify ideas three-dimensionally to validate design solutions, idea generation and evaluation. This study believes that LEGO and other materials are efficient co-design prototyping tools to ensure its main purpose for team and strategy building in enhancing participant's ability to deliver more contribution during group discussions.

Low-resolution prototyping : ideation tool and implementation of structured methodology
textLow-resolution prototyping is acknowledged as a critical step in the engineering design process, but when and how physical representations of early conceptual models should be produced is often convoluted. In this research, two studies were conducted using low-resolution prototypes and materials. In the first study, student teams were tasked with generating potential solutions to a broad-scoped engineering design task. The use of physical artifacts was studied as it relates to both ideation as well as team communication. Building upon this, teams were then assigned to construct a concept they developed, and quantitative measures were taken to assess system performance. Teams with access to physical artifacts during ideation produced a higher number of concepts as well as better performing systems. In the second study, a systematic tool was created to guide engineering teams through the low-resolution prototype design and evaluation processes. This tool is designed to have a broad application, and to assist teams in outlining a specific approach to constructing and evaluating early-stage physical models. The tool itself was evaluated to determine its effect, if any, on designers' decisions to iterate and improve concepts, as well as their decisions to conduct further concept generation based on the results of prototyping. The design and evaluation guides were then provided to undergraduate design teams and any effects due to student exposure to the guides were analyzed. Teams used them throughout their design process. Results were gathered regarding the teams' subjective views on the guides as well as their overall low-resolution prototyping process. Low-resolution physical prototyping is becoming more accessible to engineering teams of all types, and decisions on when and how resources should be allocated to this process still remain somewhat unstructured. Implementation during the ideation phase, as well as development of a systematic method for embodiment following concept generation, are two stages of design in which low-resolution prototyping appear to be effective towards achieving a successful design outcome.Mechanical Engineerin
Lightweight Interaction Modeling in Evolutionary Prototyping
The paper discusses a systematic integration of evolutionary and exploratory prototyping of interactive systems by a lightweight use of formal methods. Formal models guide the development of the underdesigned evolutionary prototype. In combination with techniques from Design Rationale, they implement theexploration and assessment of possible solutions to open design questions. Models and corresponding tool support are used to express design options and to make them more accessible to a broader audience by the creation of parallel model-guided throwaway extensions of the current evolutionary prototype. They are also used to describe design constraints (for example, in terms of tasks or in terms of actions on artifacts) and to assess design options against these criteria. The suggested approach is demonstrated through an example design scenario that shows an intertwining of different design activities and discusses the role of formal models. In particular, the scenario describes a coupling of HOPS models, QOC diagrams, and Java prototypes
LEGO and Low-fidelity Materials as prototyping Tools in Co-Creation Activities involving Multidisciplinary Participants
This study examines co-creation prototyping with LEGO and low-fidelity materials. 122 people from the fields of design, the pure sciences, forestry, and tourism are involved in this 6-hour co-creation program. The advantages of early design prototyping with LEGO and low-fidelity materials are examined in this study. LEGO and low-fidelity materials enable multidisciplinary participants to explore, analyse, and modify ideas in three dimensions, validating design solutions, idea formulation, and idea evaluation. It can be concluded that LEGO and low-fidelity materials are good co-design prototyping tools for team and strategy building because they motivate members to participate more during group discussions, manage design modifications, and demonstrate new design directions.

Design prototyping methods
textProduct development is often modeled as a cycle between phases of designing, building, and testing. This work will explore early stage build efforts of product design, which is also known as prototyping. Prototyping is a critical determinant of product success. Research shows that different approaches to prototyping can greatly affect design outcome. This work provides an integrated overview, and expansion of the existing work on design prototyping methods. Following the introduction, an extensive literature review of design prototyping tools, techniques, and methods is provided. These sources are indexed and comparatively reviewed. The capabilities of a novel hybrid prototyping technique is explored through a design case study. Next, insights from the review are integrated in a context independent prototyping strategy method. The method is developed with heuristics extracted from the literature, and additional insights from experimental studies. The technique is then experimentally evaluated. Finally, results of an extensive study of an online design repository are provided. The results include five key principles for prototype design and fabrication. The presence of these principles in the repository is validated through a novel crowd-sourced online study. The outcome effects of deploying these principles to design teams is experimentally evaluated. Overall, this research provides a guide to prototyping which includes a systematically indexed review and comparison of the existing work, as well as a novel method, and principles for design and fabrication.Mechanical Engineerin
Harnessing Different Motivational Frames via Mobile Phones to Promote Daily Physical Activity and Reduce Sedentary Behavior in Aging Adults
abstract: Mobile devices are a promising channel for delivering just-in-time guidance and support for improving key daily health behaviors. Despite an explosion of mobile phone applications aimed at physical activity and other health behaviors, few have been based on theoretically derived constructs and empirical evidence. Eighty adults ages 45 years and older who were insufficiently physically active, engaged in prolonged daily sitting, and were new to smartphone technology, participated in iterative design development and feasibility testing of three daily activity smartphone applications based on motivational frames drawn from behavioral science theory and evidence. An “analytically” framed custom application focused on personalized goal setting, self-monitoring, and active problem solving around barriers to behavior change. A “socially” framed custom application focused on social comparisons, norms, and support. An “affectively” framed custom application focused on operant conditioning principles of reinforcement scheduling and emotional transference to an avatar, whose movements and behaviors reflected the physical activity and sedentary levels of the user. To explore the applications' initial efficacy in changing regular physical activity and leisure-time sitting, behavioral changes were assessed across eight weeks in 68 participants using the CHAMPS physical activity questionnaire and the Australian sedentary behavior questionnaire. User acceptability of and satisfaction with the applications was explored via a post-intervention user survey. The results indicated that the three applications were sufficiently robust to significantly improve regular moderate-to-vigorous intensity physical activity and decrease leisure-time sitting during the 8-week behavioral adoption period. Acceptability of the applications was confirmed in the post-intervention surveys for this sample of midlife and older adults new to smartphone technology. Preliminary data exploring sustained use of the applications across a longer time period yielded promising results. The results support further systematic investigation of the efficacy of the applications for changing these key health-promoting behaviors.The article is published at http://journals.plos.org/plosone/article?id=10.1371/journal.pone.006261
