Abstract:

The ageing of the population is a reality. Along with this ageing, the prevalence of disability and diversity in the population is increasing. The World Health Organisation estimates that there are more than one billion people with disabilities in the world. Disability results from the interaction of people with impairments and environmental barriers. These barriers can range from architectural, cultural and social barriers to limitations in the use of devices. We are therefore facing an increasingly diverse society that, among other measures, requires accessible products and services.

Given this reality, the aim of this thesis is to develop and validate the INKLUGI PRO and INKLUDIRE tools in order to support designers in obtaining more accessible products/services.

INKLUGI PRO combines People-Centred Design tools (observations and interviews) with Hierarchical Task Analysis and exclusion calculation tools in three application phases: (i) to know the mode of interaction, (ii) to analyse the skills demanded and (iii) to estimate the number of people who have difficulties or cannot use a product/service. Thanks to this, INKLUGI PRO enables the comparison of the level of accessibility of different products, identifies the critical points of the interfaces pointing out the design features that limit their use and facilitates decision making in Inclusive Design processes.

The INKLUDIRE design guidelines are created, on the one hand, to help improve the accessibility gaps identified in the INKLUGI PRO evaluation and, on the other hand, to help specify the features or attributes of products to make them accessible. INKLUDIRE are based on 1,301 accessibility guidelines that are classified into 6 groups according to the capability they impact on: vision, hearing, cognition, mobility, dexterity and touch.

The validation of both tools is carried out in the household appliances sector, as the presence of this type of products in Spanish households is over 80% (in large household appliances). In order to find out about the accessibility measures promoted by the sector, 91 brands of household appliances were analysed, concluding that none of them works comprehensively on accessibility. Once this deficiency has been identified, the INKLUGI PRO and INKLUDIRE tools are applied in 5 case studies of household appliance interfaces. The application of these tools in the design process allows the development of accessible interfaces as demonstrated in the hob for visually impaired people at the Centro Stirling.
