Validation of the HADRIAN system using an ATM evaluation case study

Abstract

Abstract. 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 disabled people. 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.

Supporting a Design Driven Approach to Social Inclusion and Accessibility in Transport

“…More insights would be generated and there is a greater likelihood that conflicting requirements would be highlighted and subsequently support an opportunity to evaluate any necessary trade-offs if an intervention were to be made. Validation work with the database does support this claim with many of the insights generated by the use of HADRIAN reflecting those observed in real-world evaluations (Marshall et al, 2013;Summerskill et al, 2009). Yet the issue of representativeness is still a potential concern.…”

Supporting Inclusive Design of Mobile Devices with a Context Model

“…The system includes a database drawing from an anthropometric survey with 100 individuals with a wide range of abilities (Marshall, Case et al 2004). The aim pursued in this approach is to detect accessibility issues during the interaction between users and ATM (automatic teller machines) machines (Summerskill, Marshall et al 2009). One of the disadvantages is that the digital human models in HADRIAN are based on a series of movements and forces that are not the maximum, but, instead the comfortable range for each specific task under analysis (Porter, Case et al 2004).…”

Digital human modeling (DHM) for improving work environment for specially-abled and elderly

“…The elderly having age-related impairments and specially-abled persons (covering a wide range of disability) were selected as respondents. The HADRIAN software was validated by comparing the results of HADRIAN manikins with the actual users while performing the task such as retrieving a ticket from the machine, using ATM to obtain cash or using the lift at the railway station [44]. Hogberg et al [45] developed digital human models of the elderly by modifying the anthropometric and joint range of motion data.…”
