User-centred design and experience prototyping: Design and implementation of pre-handwriting intervention to children with coordination difficulties/dyspraxia

摘要

We have proposed a method to assist children with coordination difficulties or dyspraxia to improve their pre-handwriting skills. We have chosen an animation technique called 'Rotoscopy', a method that normally been used in animation and film production and adapted it to Rotoscopy Pre-handwriting Interface (RPI) prototypes using the interactive whiteboard (IWB) as interaction device. The motivation of this research is to discover how efficient if Rotoscopy is used beyond its normal purposes; and how it gives benefits in terms of behavioural and motivational aspects rather than commercial and profit point of view. Implementation of RPI prototypes has taken place through series of workshops with a teacher and a group of children with handwriting difficulties at a special education school in Caerphilly, Cardiff, United Kingdom. In the workshops children were given pre-handwriting activities in two different environments. They have been trained to use RPI prototypes and IWB, as well as pen and paper tasks. Their activities and action have been observed and recorded using video camera. Evaluation method is based-on video analysis of children's pre-handwriting result and their reaction and motivation during the workshop. It was learnt that majority of children who used RPI prototypes and IWB have produced better results in terms of accuracy of the drawing as compared to results of pen and paper activities. Furthermore the children were more motivated to use the prototypes and IWB rather than using pen and paper. The study's contribution to knowledge includes offering a new way to improve children's pre-handwriting skills using computer animation technique and touch-based devices.
