“…This further stresses the need to provide easy access to usability evaluation information, as provided by the IUT through the Wiki page. By considering usability as a whole, WRD developers are encouraged to consider and evaluate user needs in the early technology readiness stages, which will likely increase the quality and quantity of target user involvement and thus promote UCD (Santos et al, 2021 ; Meyer et al, 2022 ).…”

Wearable robotic devices (WRD) are still struggling to fulfill their vast potential. Inadequate daily life usability is one of the main hindrances to increased technology acceptance. Improving usability evaluation practices during the development of WRD could help address these limitations. In this work, we present the design and validation of a novel online platform aiming to fill this gap, the Interactive Usability Toolbox (IUT). This platform consists of a public website that offers an interactive, context-specific search within a database of 154 user research methods and educational information about usability. In a dedicated study, the effect of this platform to support usability evaluation was investigated. Twelve WRD experts were asked to complete the task of defining usability evaluation protocols for two specific use cases. The platform was provided to support one of the use cases. The quality and composition of the proposed protocols were assessed by (i) two blinded reviewers, (ii) the participants themselves, and (iii) the study coordinators. We showed that using the IUT significantly affected the proposed evaluation focus, shifting protocols from mainly effectiveness-oriented to more user-focused studies. The protocol quality, as rated by the external reviewers, remained equivalent to those designed with conventional strategies. A mixed-method usability evaluation of the platform yielded an overall positive image, with detailed suggestions for further improvements. The IUT is expected to positively affect the evaluation and development of WRD through its educational value, the context-specific recommendations supporting ongoing benchmarking endeavors, and highlighting the value of qualitative user research.

“…Design ideas for new systems are tested out on potential users with a prototype that is relatively quick and inexpensive to construct (Fay, 1991). Prototypes are an efficient communication tool for the user involvement (UI) process translating the language of engineering into the language of users and vice versa, allowing discussion among these stakeholders (Dos Santos, 2021). The use of prototypes allows users to express their opinion and enrich product design while fostering the creation of new knowledge for the engineering team (Dos Santos, 2021).…”

The use of prototypes allows users to express their opinion and enrich product design while fostering the creation of new knowledge for the engineering team (Dos Santos, 2021). A goal of low fidelity prototyping like the Wizard of Oz approach is to explore innovation with technologies that may exist but are not yet prototyped, the main example being an unfinished design (Arnowitz, 2007).…”

The current COVID pandemic saw a surge in the demand for vegetable seeds in the Philippines. Local farmers continued to try new vegetable crops using seeds in small packets Seed distributors struggled to keep up with the increased demand. This positive market development amidst the uncertain times necessitated the need for an improved sales forecasting system for business organizations distributing seed products. This study aimed to develop a low fidelity prototype for an in-month seed sales forecasting system. A systems analysis of the current process observed in typical seed distribution operations confirmed an opportunity for a computer-based forecasting system. During the Systems Design phase, a Hierarchical Input-Process-Output chart, a Use Case Diagram, and Data Flow Diagrams were generated. Microsoft Access was used to develop the database. Tables, queries, forms, and reports were likewise generated. Low fidelity prototyping was used using Justinmind. Compared to the current process, the new system provided several advantages. Flexibility and capability were afforded to a seed distributor, in strengthening the forecasting process to cope with the growing demand for vegetable seeds amidst the uncertainties brought about by the pandemic. An exciting opportunity is an application to the development of a coexistence system for genetically modified (GM) crop seed production. More importantly, highlighting the tools and processes leading up to the development of a simple, low-fidelity prototype provided great academic opportunities, particularly in the design of improved agricultural systems,
