Purpose of Gesture Modelling

> Create a database of Irish Sign Language gestures

> Database will consist of multiple models i.e. 3D model and human models

Creating 3D Gestures> Set up arm movements

in 3D modelling software

> Adjust hand and fingers to produce different gestures e.g. alphabet gestures

> Render all possible combinations

> Organise entire set of frames for manipulation by Database creation software

Recording Live Gestures

> Download video to a PC and extract individual frames

> Organise entire set of frames for manipulation by Database creation software

> Set up lighting, camera and scene background

> Record series of gestures for each model

Next Steps

> Enlarge the range of gestures and variety of models in the Database

> Increase efficiency of live video set up and recording time

> Fully automate generation of 3D model gestures

> Document 3D gesture setup steps and best practices used
