      Sims, Ruth; Marshall, Russell; Summerskill, Steve; Gyi, Diane E.; Case, Keith; Loughborough University (2012)
      For the last decade research by the Loughborough Design School in the UK has lead a computer-based tool called HADRIAN has been developed to encourage empathy between design professionals, policy makers, commissioning clients and potential end-users, including people who are older or who may have some form of impairment. The tool provides a means to evaluate the accessibility and inclusiveness of a design by simulating the abilities of older and disabled people and performing virtual user trials where potential barriers introduced by the proposed design can be identified and rectified before the design is implemented in the real world. This paper presents and discusses three validation trials conducted to evaluate the simulation capabilities of HADRIAN compared to real people interacting with the same tasks. Trials included two laboratory-based tasks and one field trial at a railways station.
    • Using Hadrian for eliciting virtual user feedback in 'Design For All'

      Marshall, Russell; Porter, J. Mark; Case, Keith; Sims, Ruth; Gyi, Diane E.; Loughborough University (2004)
      Design for All' is an approach to product, environment or service design that aims to maximise the usability of a particular design. However, a key concept of this approach is not to tailor designs to the user in a bespoke fashion, but rather to provide a single solution that accommodates the needs of all users including those who are older or disabled. In order to support the designer / design team in ‘Design for All’ a computer aided design and analysis tool has been developed. The tool, known as HADRIAN, has been developed to address two critical factors. The first factor is the provision of accurate and applicable data on the target users including a broad spectrum of size, shape, age and ability. The second factor is an efficient and effective means of utilising the data for ergonomics evaluations during the concept stages of design. HADRIAN’s database and task analysis tool work in combination with the existing human modelling system SAMMIE. The system as a whole allows assessment of a design against the population in the database providing a means to elicit some of the feedback that might be gained by real user trials at a stage in the design process when physical mock-ups and user group selection would be prohibitively time consuming and expensive.
    • Validation of the HADRIAN system using an ATM evaluation case study

      The HADRIAN human modelling system is under development as part of the EPSRC funded AUNT-SUE project. The HADRIAN system aims to foster a 'design for all' ethos by allowing ergonomists and designers to see the effects of different kinds of disability on the physical capabilities of elderly and people with disabilities. This system is based upon the long established SAMMIE system, and uses data collected from 102 people, 79 of whom are registered as disabled, or have age related mobility issues. The HADRIAN system allows three dimensional CAD data of new products to be imported, with a subsequent automated analysis using all of the 102 sample members. The following paper describes the process and results gathered from a validation study using an ATM design as a case study. The results indicated that fine tuning of the behavioural data built into HADRIAN would improve the accuracy of an automated product analysis.

    • Virtual fitting trails using SAMMIE and HADRIAN

      Marshall, Russell; Porter, J. Mark; Case, Keith; Sims, Ruth; Gyi, Diane E.; Loughborough University (2003)
      Fitting trials are a common technique employed in ergonomics evaluation. Fitting trials employ a panel of users carefully selected to be representative of the population at which the product, or environment, has been targeted. The panel are then used to evaluate the design against a set of criteria in order to determine a level of suitability of the design. Whilst traditionally this process has taken place with real people and full size mock-ups, increasingly the process is becoming computer supported and makes use of CAD models and human manikins in a ‘virtual’ fitting trial. The use of these technologies can clearly play a key role in supporting user-centred design, however, there are a number of shortcomings in the current technology, data, and infrastructure used for computer aided ergonomics evaluations in design. This paper will introduce HADRIAN, a computer aided ergonomics analysis tool developed at Loughborough University. HADRIAN works together with the existing system SAMMIE. The paper will focus on the novel aspects of the systems demonstrating how, together they may be employed to not only make virtual fitting trails more efficacious but also encourage empathy with the end user.
    • Virtual task analysis in 'design for all'.

      Marshall, Russell; Case, Keith; Porter, J. Mark; Gyi, Diane E.; Sims, Ruth; Loughborough University (2003)
      Design for All’ or ‘Inclusive Design’ is an approach to product, environment or service design that aims to maximise the applicability of a particular design. However, the concept is not to tailor designs in a bespoke fashion, but rather to provide a single solution that accommodates the needs of all users including those who are older or disabled. In order to educate and support the designer in their endeavours to ‘Design for All’ a computer aided design and analysis tool has been developed. The tool, known as HADRIAN, has been developed to meet two key areas of deficiency in existing approaches. HADRIAN provides improved data for the designer with a sample database of 100 individuals across a broad spectrum of ages and abilities. HADRIAN also provides a means of using this data for ergonomics evaluations through a task analysis tool. Working in combination with the existing human modelling system SAMMIE the system allows the designer to assess their designs against the population in the database to determine the percentage who are effectively ‘designed out’.
    • Virtual task simulation for inclusive design.

      Marshall, Russell; Case, Keith; Summerskill, Steve; Sims, Ruth; Gyi, Diane E.; Davis, Peter; Loughborough University (2009)
      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.

      Anthropometric data are often described in terms of percentiles and too often digital human models are synthesised from such data using a single percentile value for all body dimensions. The poor correlation between body dimensions means that products may be evaluated against models of humans that do not exist. Alternative digital approaches try to minimise this difficulty using pre-defined families of manikins to represent human diversity, whereas in the real world carefully selected real people take part in ‘fitting trials’. HADRIAN is a digital human modeling system which uses discrete data sets for individuals rather than statistical populations. A task description language is used to execute the evaluative capabilities of the underlying SAMMIE human modelling system as though a ‘real’ fitting trial was being conducted. The approach is described with a focus on the elderly and disabled and their potential exclusion from public transport systems.
