OBJECTIVE Placement of a ventricular drain is one the most common neurosurgical procedures. However, higher rate successful placements with this freehand procedure desirable. The authors’ objective was to develop compact navigational augmented reality (AR)–based tool that does not require rigid patient head fixation, support surgeon during operation. METHODS Segmentation and tracking algorithms...

In a novel experimental setting, we augmented variation of traditional compassion meditation with our custom-built VR environment for multiple concurrent users. The presence another user’s avatar in shared virtual space supports social interactions and provides an active target evoked compassion. system incorporates respiration brainwave-based biofeedback to enable closed-loop interaction users...

In this paper, an augmented reality system for automotive engineering education is introduced. Main objective of the system is teaching disassemble/assemble procedure of automatic transmission of a vehicle to students, who study automotive engineering. System includes vehicle transmission, set of tools and mechanical facilities, two video cameras, computer with developed software, HMD glasses a...

This study proposes augmented reality as a tool to access Internet information from mobile devices and prototypes for markerless outdoor augmented reality application based on SIFT (Scale Invariant Feature Transform) features are implemented. They comprise a reference data set of SIFT points extracted from images of the square Place des Terreaux in Lyons. These SIFT features are projected on a ...

Students often ask why they should learn or where would use this knowledge when learning. Real-life experiences make learning more meaningful for the students. Thus, environments students could acquire real-life are important. However, due to student profile, crowded classes, inadequate course hours, technological advances, natural disasters, etc., conventional instruction methods not meet requ...
