In this paper we discuss Augmented Reality (AR) displays in a general sense, within the context of a Reality-Virtuality (RV) continuum, encompassing a large class of "Mixed Reality" (MR) displays, which also includes Augmented Virtuality (AV). MR displays are defined by means of seven examples of existing display concepts in which real objects and virtual(More)
This paper details the design and evaluation of the <i>Delphian Desktop</i>, a mechanism for online spatial prediction of cursor movements in a Windows-Icons-Menus-Pointers (WIMP) environment. Interaction with WIMP-based interfaces often becomes a spatially challenging task when the physical interaction mediators are the common mouse and a high resolution,(More)
Like the prehistoric twig and stone, tangible user interfaces (TUIs) are objects manipulated by humans. Tangible user interface success will depend on how well they exploit spatiality, the intuitive spatial skills humans have with the objects they use. In this paper, we carefully examine the relationship between humans and physical objects, and related(More)
An ideal stereoscopic display system for multiple users is proposed. It allows three or more people to simultaneously observe individual stereoscopic image pairs from their own viewpoints. The system tracks the head positions of all of the users and generates distortion-free images for each eye of each user. The system consists of a normal display and a(More)
ActiveCube is a novel user interface that allows intuitive interaction with computers. ActiveCube allows users to construct and interact with three-dimensional (3D) environments using physical cubes equipped with input/output devices. Spatial, temporal, and functional consistency is always maintained between the physical object and its corresponding(More)
In this paper, we extensively evaluate the effectiveness of using a user's social media activities for estimating degree of depression. As ground truth data, we use the results of a web-based questionnaire for measuring degree of depression of Twitter users. We extract several features from the activity histories of Twitter users. By leveraging these(More)
We propose a manipulation technique to intuitively control the “bird’s eye” overview display of an entire large-scale virtual environment in a display system that present a user with both overviews (global views) and a life-size virtual environment (local view) simultaneously. It enables efficient navigation even in enormous and complicated environments(More)
A natural and intuitive method is proposed to help a user manipulate an object in a virtual environment. The method does not need to assign special properties to the object faces in advance and does not require special hardware. Instead, it uses only the visual constraints of motion among object faces that are dynamically selected by a real-time collision(More)
