The Psychrometric Chart tutorial is a downloadable animated tutorial application which explains the various features of the Psychrometric Chart and how it illustrates indoor or outdoor air conditions and their relation to human thermal comfort. This tutorial is written in Flash and various audio-visual techniques are incorporated to create an effective educational resource. This paper outlines ...

We present Fireflies, an exploration of bio-inspired visualization using animal swarming behaviours and plant phyllotaxis. We applied Fireflies to a Canadian attitudinal survey on HIV/AIDS. Information about the survey participants is encoded within different visual elements of fireflies; most importantly, the motion of the fireflies depicts comfort levels concerning HIV/AIDS. The bio-inspired ...

Compared to traditional 2D image techniques, stereoscopic techniques provide additional information the binocular depth, which strongly enhances the immersion. However, it may also cause visual comfort problems because it is still not a perfect representation of natural human vision but to some extent an illusion. How to fairly evaluate and understand the QoE (Quality of Experience) of stereosc...

The 3D image/video quality of experience is a multidimensional concept that depends on 2D image quality, depth quantity and visual comfort. The relationship between these parameters is not yet clearly defined. From this perspective, we aim to understand how texture complexity, depth quantity and visual comfort influence the way people observe 3D content in comparison with 2D. Six scenes with di...

In the smart home environment, efficient energy management is a challenging task. Solutions are needed to achieve a high occupant comfort level with minimum energy consumption. User comfort is measured in terms of three fundamental parameters: (a) thermal comfort, (b) visual comfort and (c) air quality. Temperature, illumination and CO2 sensors are used to collect indoor contextual information....

OBJECTIVES To compare the clinical performance of the Clearkone hybrid contact lens for the treatment of keratoconus against the habitual contact lens of the patients. METHODS A total of 33 eyes from 18 patients were fitted with the Clearkone. High- and low-contrast visual acuity (HCVA and LCVA), central corneal thickness (CCT), and contrast sensitivity acuity (CSF) were recorded with habitua...

background: creating a socket with proper fit is an important factor to ensure the comfort and control of prosthetic devices. several techniques are commonly used to cast transtibial stumps but their effect on stump shape deformation is not well understood. this study compares the dimensions, circumferences and volumes of the positive casts and also the socket comfort between two casting method...

Previous studies have shown that indoor environmental quality (IEQ) parameters may a considerable effect on office employees’ comfort, health and performance. Therefore, we initiated research program to help occupants identify IEQ they perceive as risk factors for their in an enhance comfort levels environment. Since assumed employees might different expectations related work area these differe...

The purpose of this study was to compare the influences of 4 ankle conditions (no support, bracing, taping, taping + spatting; all in football cleats) during 2 maximal-effort field drills (40-yd dash and 34-yd cutting drill) on perceptions of comfort and stability and performance outcomes. Fourteen young adult males participated. Subjects' perceptions of comfort and stability were assessed by v...
