“…However, despite its widespread use and potential value, the method of personas has also received firm criticism from design researchers. A major point of critique is the lack of possibilities to check personas' validity (Chapman & Milham, 2006), reason for several researchers to publish their efforts to validate personas (Subrahmahiyan, Higginbotham & Bisantz, 2017;Vincent & Blandford, 2014). Although these studies are valuable additions to literature, we are nowhere near a gold standard how to validate personas.…”

How to create personas to improve designs for behaviour change strategies in the public domain? Three recent cases illustrate lessons learnt and challenges encountered during persona development in the public domain. Personas were helpful to gain insight into diversity within a target group, to create empathy for its members, and to have a shared understanding when communicating about them. The main challenges encountered were 1) capturing complex behaviour with personas, as the behaviours involved were variable over time, the (legislative) environment in motion, and the target groups diverse; 2) finding the right balance between intuitive vs. evidence-based decision-making, a process we coined "taking a responsible leap of faith"; and 3) transferring personas to third parties, as free sharing of insights and tools is common in the public domain. Validation plays an important role in personas' transferability. We call for all involved researchers to share experiences with using the persona methodology in the public domain, in order to tackle the challenges, and to create a more standardised way of developing personas.

“…Augmentative and alternative communication (AAC) is a way for an individual with a speech impairment to convey a message through a range of different modes, such as facial expressions, non-speech vocalizations, personal communication books, and speech-generating devices (Subrahmaniyan, Higginbotham & Bisantz, 2017;Teachman & Gibson, 2018). AAC can vary from low-tech to high-tech methods.…”

“…When developing an AAC design, developers may not be trained to design for/with users. Another reason, researchers have given for the lack of HCD in AAC device development stems from clients' limited ability to communicate effectively to be able to fully participate in design and development (Subrahmaniyan et al, 2017).…”

“…Although SensAct easily as they conduct the AAC assessments and work with their clients on a daily basis, not the developers. In this scenario, the 'real consumer' of the AAC device is not necessarily just the client who uses the device, but rather the clinicians who prescribe and implement the AAC device (Subrahmaniyan et al, 2017). Also, from an ethical perspective, clinicians need to fully comprehend the device's capability before they can make sound recommendations to their client.…”

“…The "real consumer" of an AAC device may not be the client who uses the device itself, but rather the healthcare specialists who prescribe and implement the AAC device (Subrahmaniyan et al, 2017). SensAct developers should design a system that caters to the skills and knowledge of the healthcare specialists.…”

Improving SensAct’s Usability and Potential to Support Augmentative and Alternative Communication (AAC) Using Human-Centred Design Methods

Individuals living with speech impairments may require an augmentative and alternative communication (AAC) device to be able to speak or interact with other people. The implementation of an AAC device is fundamental to facilitate effective communication, expand social interaction, and to be part of the community. A team of developers at Bruyère-Saint-Vincent Hospital has been developing an AAC device called SensAct to fulfill those needs. Despite extensive advancements, stakeholders at the hospital feel the technology has usability issues preventing it from being implemented and used by a wider target audience. This study aims to investigate factors influencing SensAct's usability, specifically, focusing on SensAct's user interface (UI) and usability issues that arise when configuring the system for healthcare clients. Using qualitative methods from human-centred design, this study identified systemic factors that influence AAC/SensAct implementation, and three key usability issues that may undermine SensAct's ability to reach a broader audience: time constraints, the use of complex technical terms, and complex UI with minimal support. These findings informed the development of design recommendations to develop SensAct's UI. At a broader level, this study provides a basic framework to support further studies on SensAct to accomplish the goals of healthcare workers to better meet the needs of their clients.

The design and development of computer assistive technologies must be tied to the needs and goals of end users and must take into account their capabilities and preferences. In this paper, we present MeDeC@, a Methodology for the Development of Computer Assistive Technologies for people with Autism Spectrum Disorders (ASD), which relies heavily in our experience working with end users with ASD. The aim of this methodology is not to design for a broad group of users, but to design highly customizable tools so that they can be easily adapted to specific situations and small user groups. We also present two applications developed using MeDeC@ in order to test its suitability: Emo-Traductor, a web application for emotion recognition for people with Asperger Syndrome, and ReadIt, a web browser plug-in to help people with ASD with written language understanding difficulties to navigate the Internet. The results of our evaluation with end users show that the use of MeDeC@ helps developers to successfully design computer assistive technologies taking into account the special requirements and scenarios that arise when developing this kind of assistive applications.
