An introduction to the person-centred approach as an attitude for participatory design

This paper is one of three talks which reflect on the use of participatory design methods, especially in the context of design for mental health and wellbeing. In them we: introduce the Person-Centred Approach as a framework for conducting Participatory Design; outline the method of Interpersonal Process Recall (IPR); and present a heuristic case study of these approaches being developed by a multidisciplinary design research team with Mind, a UK mental health charity. In this paper, we introduce the Person-Centred Approach (PCA) as found in psychotherapy, education and conciliation processes. We propose that this approach can help the field of Participatory Design recognise that researchers and research teams constructively inform their practice through the attitudes they bring to what is necessarily a relational situation. The PCA will be of interest to researchers working with mental health and wellbeing communities in particular, but may also be valuable in offering a framework for Participatory Design as a broad field of practice. The paper describes different modes of practice to be found in psychotherapy and outlines key aspects of the PCA, before discussing its implications for doing Participatory Design

An introduction to IPR as a Participatory Design research method

This paper outlines the method of Interpersonal Process Recall (IPR) as a Participatory Design method, especially in the context of design for mental health and wellbeing. IPR is more commonly used in psychotherapy and other helping professions to help trainees and practitioners and their clients reflect on their process, using AV recordings of interactions for the facilitation of deep and accurate recall. We propose that it can provide a mechanism for reflection on team working and relational aspects of Participatory Design. The paper discusses the rationale for using IPR and the ways in which the method relate to phenomenological inquiry (including the Person-Centred Approach); it describes an IPR research method protocol, and finishes with a discussion of the implications for Participatory Design methodologies

Sensitivity analysis modelling for microscale multiphysics robust engineering design

Sensitivity Analysis (SA) plays an important role in the development of any practical engineering model. It can help to reveal the sources and mechanisms of variability that provide the key to understanding system uncertainty. SA can also be used to calibrate simulation models for closer agreement with experimental results. Robust Engineering Design (RED) seeks to exploit such knowledge in the search for design solutions that are optimal in terms of performance in the face of variability. Microscale and multiphysics problems present challenges to modelling due to their complexity, which puts increased demands on computational methods. For example, in developing a model of a piezoelectric actuator, the process of calibration is prolonged by the number of parameters that are difficult to verify with the physical device. In the approach presented in this paper, normalised sensitivity coefficients are determined directly and accurately using the governing finite element model formulation, offering an efficient means of identifying parameters that affect the output of the model, leading to increased accuracy and knowledge of system performance in the face of variability

Bond graph based sensitivity and uncertainty analysis modelling for micro-scale multiphysics robust engineering design

Components within micro-scale engineering systems are often at the limits of commercial miniaturization and this can cause unexpected behavior and variation in performance. As such, modelling and analysis of system robustness plays an important role in product development. Here schematic bond graphs are used as a front end in a sensitivity analysis based strategy for modelling robustness in multiphysics micro-scale engineering systems. As an example, the analysis is applied to a behind-the-ear (BTE) hearing aid. By using bond graphs to model power flow through components within different physical domains of the hearing aid, a set of differential equations to describe the system dynamics is collated. Based on these equations, sensitivity analysis calculations are used to approximately model the nature and the sources of output uncertainty during system operation. These calculations represent a robustness evaluation of the current hearing aid design and offer a means of identifying potential for improved designs of multiphysics systems by way of key parameter identification
