HCIs - Disabled Access

Examples of user requirements that should be taken into account when designing a user interface for use by disabled people.

• Visually impaired people can have their screens configured using large fonts.

• Magnify areas of the screen for people with poor eyesight.

• Visually impaired people can also use special Braille keyboards to enter the data and can use Braille printers to produce output which other blind people can read.

• Visual messages on screen instead of sound for the deaf.

• Use of correct colour schemes for colour blind people.

• Use large mouse or trackerball for people with poor co-ordination.

• Blow pipes (sip and puff switches) or eye movements for entering text controlling devices for those who cannot use their arms, etc.

• Brainwave controlled devices for physically handicapped with no arm/hand movement.

  • e.g. Mind controlled device i.e. Ipsihand can help stroke patients move their hands (See https://www.wired.co.uk/article/brain-implants-stroke-patients-paralysis)
