Pseudo-haptics, a form of haptic illusion exploiting the brain's capabilities and limitations, has been studied for about a decade. Various interaction techniques making use of it emerged in different fields. However, important questions remain unanswered concerning the nature and the fundamentals of pseudo-haptics, the problems frequently encountered, and sophisticated means supporting the development of new systems and applications. We provide the theoretical background needed to understand the key mechanisms involved in the perception of / interaction with pseudo-haptic phenomena. We synthesise a framework resting on two theories of human perception, cognition and action: The Interacting Cognitive Subsystems model by Barnard et al. and the Bayesian multimodal cue integration framework by Ernst et al. Based on this synthesis and in order to test its utility, we discuss a recent pseudo-haptics example. Finally, we derive system design recommendations meant to facilitate the advancement in the field of pseudo-haptics for user interface researchers and practitioners.

1The Perception of Lighting Inconsistencies in Composite Outdoor Scenes
"... It is known that humans can be insensitive to large changes in illumination. For example, if an object of interest is extracted from one digital photograph and inserted into another, we do not always notice the differences in illumination between the object and its new background. This inability to ..."

It is known that humans can be insensitive to large changes in illumination. For example, if an object of interest is extracted from one digital photograph and inserted into another, we do not always notice the differences in illumination between the object and its new background. This inability to spot illumination inconsistencies is often the key to success in digital “doctoring” operations. We present a set of experiments in which we explore the perception of illumination in outdoor scenes. Our results can be used to predict when and why inconsistencies go unnoticed. Applications of the knowledge gained from our studies include smarter digital “cut-and-paste ” and digital “fake ” detection tools, and image-based composite scene backgrounds for layout and pre-visualization.
