Title
A study of touchless versus touch-based interactions with bacterial biofilm images
Abstract
Bacteria reproduce simply and rapidly by doubling their contents and then splitting in two. The majority of bacteria in the human body are countered by the human immune system, however some pathogenic bacteria survive and cause disease. Enabling of remote control and visualization of pathogenic species can reduce direct exposure of researchers. The visualization of augmented biological data can also speed up the extraction of useful information. This can be achieved using contactless interactions with viewed scenes, by the use of camera based gesture recognition technologies. Utilising an immersive environment such as a 3-D hemispherical dome for visualization can also enhance user experience when exploring complex interior structures and morphology of bacteria during the course of biofilm formation. Our aim is to uncover limitations of current technology for the design of a real-time natural contactless interactive system. In this work, Human Computer Interaction (HCI) experiments are carried out with Creative Interactive Gesture Camera as a touchless input device to track a user's hand gestures and translate them into the natural field of view or point of focus. In experiments, the touchless interface is compared with a touch-based system using an iPad device during a task-oriented user study. Conclusions are drawn based on statistical analysis of user experience in interaction experiments with microscopy images of bacteria in bacterial biofilm formation. Future investigations will use an the dome immersive environment where 3D bacterium shapes will be visualized from their 2D images.
