Haptic perception is context dependent, suggesting that haptic cues in one particular domain of applications may not be suitable for another. Literature suggests that options should be given to users to allow customisation of feedback received to fit their needs. How these options should be presented has not been investigated. Also, little has been reported with respect to haptic cues in drawing, a fundamental domain in art. This research explores haptic sensations that artists recognise in a drawing environment and investigates design representations to support those sensations. It addresses these inter related questions: (1) What are the haptic features involved in drawing (2) What haptic cues are suitable for a drawing application and how to integrate them (3) In such an application, do users prefer to interact with an interface design that has a "fixed haptic" sensation or its "variable haptic" counterpart (4) If a variable haptic design is preferred, do users prefer to interact with haptic information represented in the system using an interface metaphor that involves a real world object-based representation whose underlying haptic sensation feels similar to its real world counterpart, or a textual description of the underlying feature that corresponds to an intuitive haptic sensation These questions were addressed in three practical aspects of research work: a study to capture the design requirements, implementation of the haptic interfaces, and a main evaluation study. The first study resulted in a taxonomy of haptic cues for drawing. The haptic cues for a drawing application were integrated into two different types of interface. The integration was motivated by the role and reification of metaphor to make haptic information concrete. An evaluation study tested users' preferences on these design representations suggesting a preference for a variation of force feedback. The findings suggest that both designs have potential to be accepted by users.
