Abstract
We have proposed a method to assist children with coordination difficulties or dyspraxia to improve their 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 Prehandwriting 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? Does it give benefits in terms of behavioural and motivational aspect 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 using pen and paper. Their activities and action has 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 are more motivated to use the prototypes and IWB rather than using pen and paper. The study’s contribution includes offering a new way to improve children’s prehandwriting skills using computer animation technique and touch-based devices.
Highlights
Rotoscopy is a traditional animation technique that has been comprehensively adopted in computer animation
As our research aims to give children with dyspraxia a playful and physical experience in developing their handwriting skills, we are investigating rotoscopy technique to identify whether motivation and engagement can be increased by using a performance-led embodied approach, which would allow children to practice handwriting using gross motor skills, for example bodily movement and gesture
The first study examined how children squiggle using the first module of Rotoscopy Prehandwriting Interface (RPI) prototypes called RPI (Squiggles)
Summary
Rotoscopy is a traditional animation technique that has been comprehensively adopted in computer animation It captures human movement in such a way that it can be animated in a simplified form to convey naturalistic actions [1][2]. Rotoscopy technique was invented in 1917 by Max Fleisher for his film, Out of the Inkwell It is named after projection equipment called the Rotoscope; where pre-recorded live-action film images were projected onto a frosted glass panel and re-drawn by an animator. In this example, graphics images as well as human motion and body shape from a video sequences were traced manually using rotoscopy system to get the image silhouettes, which are been transformed to 2D graphics and animation. We can create a new 2D graphics or character that are different from original object but inherits its shapes and motion
