Sylvain Malacria is a Post-Doctoral researcher in the HCI lab with Prof. Cockburn at the University of Canterbury, New-Zealand. His research interests are in the areas of human-computer interaction (HCI), with additional focus on designing new interaction techniques. He especially focuses on understanding and improving the transition from novice to expert mode in graphical interfaces. During his Ph.D., he worked on identifying which type of resources (software and hardware) can be used to enrich the input bandwidth.

Most interfaces support more than one interaction modality for accessing the same function. Intermodal expertise improvement concerns the transition from slower "novice" modalities to faster "expert" ones that ultimately offer a higher performance ceiling. Several factors can act as deterrents to users switching to the expert modality, such as requiring to memorize an abstract mapping between a user action and the activated command, or the perception of performance with different modalities. In this talk, I will be presenting my work toward Improving user's intermodal expertise with software applications. In particular, I will explain the design and evaluation of systems for helping users to improve their intermodal expertise while interacting with desktop computers and touch-sensitive surfaces.
