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

Error Analysis

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

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

Error Analysis. use adv & disadvs from ppt

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

Fast? efficently? without exerting effort?

Culture

Japan use palm recognition because they dont like to touch tings

Voice

Palm

Finger

Walking Posture

Iris

FAR has to be 0%?

Optimal viewing angle Vs need to accomodate variety of heights

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

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.

The text screen should be of sufficient size to see

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

Dynamic Fitting Trial

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

Dynamic / task related anthropmetery

Trial design with representative sample of users

Mockups to use for fitting trials?

Sightlines, size of text, buttons, layout

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

Zone of convenient reach for input card / get money

Focus on needs of limiting User in this section

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

novice / expert

Cultural differences? in UK

Spatial arrangement of controls

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

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

Users

Public

Secure Van people

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

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.

Cleaners

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

Everybody needs money

Age and disabilities

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?

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

Hex-spindle model?

Screen glare

Think of future. other banks? need consistancy

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

Trade off between security and screen viewing angles

Safety of money. robust?
