A basic issue in the development of see-through display systems is obtaining precise calibration for the system in relation to the user. Unlike immersive head-mounted displays (HMDs) where only virtual objects are displayed, even small discrepancies in the location of the virtual images can be dis-orienting. Moreover, any discrepancies in global scaling or distortions of virtual objects impairs...

In many construction building systems courses, two-dimensional (2D) diagrams are used in text books and by the instructors as teaching aid. This conventional approach may not be sufficient enough to convey the actual representation of the building system. It can lead to confusion and misunderstanding to students who are particularly new to the subject matter in hand. Research has suggested that...

There are various designs of tools and equipment used for harvesting the crops and threshing it separately. Sickles, hand tools and reapers for grain crops and diggers for tuber crops and rhizomes, operated with different power sources are used. Combine harvesters, both tractor mounted and self-propelled, are being very widely used for different grain crops. Functional requirements and principl...

While Virtual Reality applications are increasingly attracting the attention of developers and business analysts, the behaviour of users watching 360-degree (i.e. omnidirectional) videos has not been thoroughly studied yet. This paper introduces a dataset of head movements of users watching 360-degree videos on a Head-Mounted Display (HMD). The dataset includes data collected from 59 users watc...

This paper examines the effect that changing arena (i.e. an immersive CAVE or head mounted display) and adding an augmented barrier has on the sense of place and presence in two photo-realistic virtual environments. Twenty eight subjects (17 male, 11 female) mainly undergraduate students or staff took part. The paper summarises two experiments that used a range of data capture methods including...

New generations of smart phone based stereoscopic HMDs (Head Mounted displays) enter the mass market. As in content production for Cinema as well as for 3DTV, human factors and specific viewing conditions must be considered for the creation of new stereoscopic contents on smart phones. This article analyzes the stereoscopic viewing conditions in smart phone based HMDs and demonstrates how the v...

The purpose of the design project is to apply and commercialise laboratory research into a marketable product. To apply design method and the correct technological specifications to the final product, utilize comp uter aided integrated design, Reverse Engineering and Rapid Prototyping technique to complete the industry design and develop a product design strategy that can bring the product to m...

For the NARVIS project two critical stages of minimal invasive spinal trauma surgery have been identi ed that can be improved with advanced visualization of imaging data. The stages port placement and pedicle screw placement require anatomical imaging data in order give the surgeon su cient information for performing his task. Port placement is a very early stage of the procedure that determine...
