layout – QWERTY

  • Standardised layout

but …

  • non-alphanumeric keys are placed differently
  • accented symbols needed for different scripts
  • minor differences between UK and USA keyboards
  • QWERTY arrangement not optimal for typing
  • layout to prevent typewriters jamming!
  • Alternative designs allow faster typing but large social

base of QWERTY typists produces reluctance to change.

special keyboards

• designs to reduce fatigue for RSI

• for one handed use

e.g. the Maltron left-handed keyboard

Chord keyboards

only a few keys - four or 5

letters typed as combination of keypresses

compact size

  • ideal for portable applications

short learning time

  • keypresses reflect letter shape

fast

  • once you have trained

BUT - social resistance, plus fatigue after extended use

NEW – niche market for some wearables

Handwriting recognition

• Text can be input into the computer, using a

pen and a digesting tablet

  • natural interaction

• Technical problems:

  • capturing all useful information - stroke path,

pressure, etc. in a natural manner

  • segmenting joined up writing into individual letters
  • interpreting individual letters
  • coping with different styles of handwriting

• Used in PDAs, and tablet computers …

… leave the keyboard on the desk!

Speech recognition

• Improving rapidly

• Most successful when:

  • single user – initial training and learns peculiarities
  • limited vocabulary systems

• Problems with

  • external noise interfering
  • imprecision of pronunciation
  • large vocabularies
  • different speakers

positioning, pointing and drawing

mouse, touchpad

trackballs, joysticks etc.

touch screens, tablets

eyegaze, cursors
