ATM

Environmental Issues

Safety of money. robust?

Trade off between security and screen viewing angles

Can't build for adjustability? out side. must be robust.

Think of future. other banks? need consistancy

Screen glare

Hex-spindle model?

Target Population

Users change over time, people in a rush, diff moods, get money out when drunk?

Accessability for disabled users is very important in this instance. It is law, legal requirements? state the law involved, thus this could effect having 2 at different heights? or must they go in side?

Age and disabilities

Generally public systems like ATMS have to cater for a wide variety of users

Everybody needs money

Users

Cleaners

Secure Van people

This effects where the device can be installed. also worth looking for building drawings inorder to work out where it would be possible. or consulating a builder.

worth doing some interviews with these users earlier rather than later. to keep their perspective in mind

Public

Aware of limiting user & their needs. State this. upper or lower boundries /clearance / sightlines/reach

Application of guidelines & Anthropometry

Spatial arrangement of controls

Feel, sensitivity, size, labelling affordances etc 27/10 lecture notes

Focus on needs of limiting User in this section

Cultural differences? in UK

novice / expert

individual / group i.e for elderly or imparied visual / auditory

Zone of convenient reach for input card / get money

ATM guidlines VS anthropometric data? i.e user expects the ATM to look / act in the same way - user will have appropriate mental model

Sightlines, size of text, buttons, layout

Mockups to use for fitting trials?

Trial design with representative sample of users

Dynamic Fitting Trial

Dynamic / task related anthropmetery

Both are psychophysics, ie the data are judgements of acceptability by people

Development of ergonomic design limitations

the dpeth / height of the ATm should be in the zone of reach, ZCR for as many users as possible.

The text screen should be of sufficient size to see

the buttons should be large & durable enough to whether both the outdoor and constant use of the system, aswell as big enough for the 95% of users hands.

Height of cill should be low enough so that a whll chair can see the screen

Optimal viewing angle Vs need to accomodate variety of heights

Biometrics

FAR has to be 0%?

Iris

Walking Posture

Finger

Palm

Voice

Culture

Japan use palm recognition because they dont like to touch tings

User Requirements

Fast? efficently? without exerting effort?

Observations, how do people use cash points now? e.g do they need somewhere to rest their purse or walet?

Task Considerations

Error Analysis. use adv & disadvs from ppt

HTA will identify missmatches between the task and users. Bodyspace. Page13 good info on here

Photographic analysis of other cash points as an idea board type thing

Error Analysis

View Balance

Get Money

Task Analysis on what needs to be done to get cash

Decision (cognitive task)

Derived

Info required, inputted, feedback

automatic

inherent knowledge

Action

Posture

Workspace design

Effort

Biomechanics

manipulative skill

Design of controls

once done, eqip necces % spec enviro become clear

Important info bits

Page 20 of PE booklet has ergonomic design approach

HOW AND WHERE IT IS TO BE INSTALLED

DIMENSIONS OF DEVICE

LAYOUT OF DISPLAYS AND CONTROLS

Explain what each stage is, how to do it, and what kind of things we get out of it
