HADRIAN: a virtual approach to design for all

This article describes research into the area of ‘design for all’. The research addresses two common needs for designers working towards developing inclusive products and environments, namely, data on users that are accessible, valid and applicable, and a means of utilising the data to assess the accessibility of designs during the early stages of development. The approach taken is through the development of a combined database and inclusive human modelling tool called HADRIAN. Data were collected on 100 people, the majority of whom are older or have some form of impairment. These individuals provide a browsable resource spanning size, shape, capability, preferences, and experiences with a range of daily activities and transport-related tasks. This is partnered with the development of a simple, CAD-based task analysis system. Tasks are carried out by the virtual individuals in the database and accessibility issues are reported, allowing excluded people to be investigated in order to understand the problems experienced and solutions identified. HADRIAN is also being expanded to include a more accessible journey planner that provides accessibility information to both end users and transport professionals. Together, HADRIAN allows more informed choices to be made either in travelling, or in the designing of products and environments.

Virtual Task Simulation for Inclusive Design

Human modelling tools provide a means to perform virtual task evaluations upon designs within the computer environment. The ability to evaluate the accommodation of a design early on in the design process before physical prototypes can be built has many advantages. These advantages are particularly relevant in supporting people in attempting to design products that are inclusive and accessible. HADRIAN is a new tool developed to provide accessible, and applicable data on people with a broad range of size, age, and ability together with a means of optimising virtual task evaluations. This paper describes the use of HADRIAN in performing a task evaluation, focusing on the underlying methodology that aims to achieve a virtual simulation that mimics a real world user trial.

Multivariate Design Inclusion using HADRIAN

This paper details the development of our computer based design tool: HADRIAN. Developed to address the area of user accommodation within design and in particular the support for ‘design for all’, HADRIAN provides an integrated database and analysis system. The data element of HADRIAN is an attempt to simplify the understanding and use of ergonomics data by the design community in addition to encouraging empathy with the end user. Anthropometry and functional abilities were collected from 100 individuals many of whom are older or have some form of disability. In addition, behavioural data was collected from the individuals performing common tasks associated with daily living and the use of transport. The individuals in the database effectively form a virtual user group that can then be used to investigate and evaluate a concept design of a product, or environment through a task analysis feature. Further developments for the HADRIAN tool also include an inclusive journey planner that allows individual travellers, or transport planners to evaluate the inclusiveness of a particular route. Together this package of tools provides a richer, more accessible set of data for human modelling and ergonomics design, and a means to assess the inclusiveness of a product, environment, or journey.
