									             Text input and young
                    children
              A study of current
              practice

Introduction
     The purpose is to ascertain how schools
     use the PC as a tool for young children
     writing – identifying problems and
     suggesting strategies for overcoming
     these. In particular, to establish if any
     alternative input devices are being
     used.

Motivation
     Lecturer in Computing at UCLAN –
     working towards a PhD – input devices
     and writing
     Mother – ‘Where’s the ‘m’ on the
     keyboard mummy?’
     Interest in language impaired children
     and their interaction with the computer

Topics of Discussion
     Three main areas
         Evidence from earlier research
         Evidence from local survey
         Investigation into possible future ideas

Government Statistics
     Primary schools have £24 per child to
     spend on computers
     13 children per computer
     52% schools use computers
     ‘substantially’ for English
     36% machines over 5 years old

Local survey findings
     Supporting information and examples
     Availability and usage
     Problems encountered
     Typical applications used

Details of the Survey
     Random selection of schools sent two
     questionnaires each
         IT survey
         Writing survey
     Findings
         Children typically have 30 mins. Per week
          on a machine
         Between 1.5 and 2.5 machines per class

Comments by teachers
     School tries to ensure equal access
     Children get frustrated if the work looks
     different from their written piece – ‘a’
     and ‘t’ typically
     Infant children not familiar with the
     keyboard – getting capital letters
     Some children are slow typists

29/09/2012        J C Read - UCLAN 2000     14
Possible New Developments
     Natural language technologies
         ‘Disobedient’ interfaces
         Voice recognition
         Handwriting recognition




29/09/2012            J C Read - UCLAN 2000   15
Early results
     Keyboard usage
         55 Characters in 12 minutes
     Voice input
         Low accuracy rates with young children
         Difficult to train
     Handwritten input
         Little training needed
         80%+ accuracy

29/09/2012             J C Read - UCLAN 2000       16
What findings suggest further
study?
     Keyboard mastery may be especially
     hard for some children- which ones?
     Voice and Pen input are the way
     forward for adult interfaces – is this the
     same for children?
     How will children react to ‘disobedient’
     interfaces?

29/09/2012         J C Read - UCLAN 2000     17
Where to next?
     Building a test environment to enable
     comparisons to be made between the
     performance of interfaces
     Devising a method of measuring the
     satisfaction of children using devices
     Making modifications to ‘intelligent’ and
     ‘disobedient’ features as required

   Thank you!
   Any questions?
