The Tinmith-Hand user interface uses: ! Tracking of the head and hands to provide 3D cursors (fig 2) ! Direct manipulation and image plane techniques for the manipulation of 3D objects close up or far away ! Custom pinch gloves (fig 2,3) that are used to control a new type of menuing system ! Each menu item is mapped to a unique finger on the gloves, and the user traverses the menu using only s...

Purpose – The different senses of the term information in physical, biological and social interpretations, and the possibility of connections between them, are addressed. Special attention is paid to Hofkirchner's Unified Theory of Information (UTI), proposing an integrated view in which the notion of information gets additional properties as one moves from the physical to the biological and th...

James Paul Gee’s Unified Discourse Analysis: Language, Reality, Virtual Worlds, and Video Games not only offers a comprehensive theoretical framework that can be used to analyze discourse, video games, and action, but also explores the underlying commonalities that unite these seemingly disparate domains. The root of Gee’s theory is that “conversations” are not limited to talk, but also include...

Augmented Reality (AR) and Mixed (MR) have been two of the most explosive research topics in last few years. Head-Mounted Devices (HMDs) are essential intermediums for using AR MR technology, playing an important role progress these areas. Behavioral with users is one way evaluating technical effectiveness HMDs. In addition, technology dependent upon virtual interactions real environment. Thus,...

Anytime a robot manipulator is controlled via visual feedback, the transformation between and camera frame must be known. However, in case where cameras can only capture portion of order to better perceive environment being interacted with, there greater sensitivity errors calibration base-to-camera transform. A secondary source uncertainty during robotic control are inaccuracies joint angle me...

In this paper, the optimal design of supplementary controller parameters of a unified powerflow controller(UPFC) for damping low-frequency oscillations in a weakly connected systemis investigated. The individual design of the UPFC controller, using hybrid particle swarmoptimization and gravitational search algorithm (PSOGSA)technique under 3 loadingoperating conditions, is discussed. The effect...
