the aim of the present study was to investigate coaches and young athletes' self-efficacy andyoung athletes' enjoyment from physical activity. the study examined the effect of self-efficacy on enjoyment from physical activity in young athletes using structural equation model (sem) and lisrel software. results showed thatcoaches' self-efficacyhad no significant effects onstudents&...

farming organic vegetable and crops have grown as a market desiring commodity. weed control in farms has been costly and laborous and it has always been hard to achieve a proper weeding. a few chemicals are commonly applied in organic farming. thermal weeding with flame burners seems a good solution; however, it has its own drawbacks, such as; damaging the main crops, low performance, being inf...

With the introduction of a new head-mounted displays models on the consumer market, the interest to those devices raised dramatically in the recent past. Although only a few wireless head-mounted display models are available today, there is a certain range of applications where those are required. Existing solutions that allow using conventional head-mounted displays for such applications wirel...

In this paper, we described the imagination scenarios of a touch-less interaction technology for hemiplegia, which can support either hand or foot interaction with the smartphone or head mounted device (HMD). The computer vision interaction technology is implemented in our previous work, which provides a core support for gesture interaction by accurately detecting and tracking the hand or foot ...

Conventional head-mounted displays (HMDs) consisting of a pair of miniature projection lenses, beam splitters, and miniature displays mounted on the helmet, as well as phase conjugate material placed strategically in the environment have been redesigned to integrate the phase-conjugate material into a complete see-through embodiment. Some initial efforts of demonstrating the concept was followe...

One obstacle to safety in the operating room is anesthesiologist distraction -having to shift attention back and forth from the patient to vital sign monitor while performing either routine or emergency procedures. The purpose of this study was to measure the decrease in anesthesiologist distraction made possible by using a head-mounted, see-through personal display (HMD) using retinal scanning...

Visual function of lens accommodation was measured while subjects used stereoscopic vision in a head mounted display (HMD). Eyesight with stereoscopic Landolt ring images displayed on HMD was also studied. In addition, the recognized size of virtual stereoscopic images was estimated using the HMD. Accommodation to virtual objects was seen when subjects viewed stereoscopic images of 3D computer ...

In this paper we propose a definition for Peripheral Head-Mounted Display (PHMD) for Near Field Displays. This paper introduces a taxonomy for head-mounted displays that is based on the property of its functionality and the ability of our human eye to perceive peripheral information, instead of being technology-dependent. The aim of this paper is to help designers to understand the perception o...

This paper describes a methodology based on human judgments of memory awareness states for assessing the simulation fidelity of a Virtual Environment (VE) in relation to its real scene counterpart. In order to demonstrate the distinction between task performance based approaches and additional human evaluation of cognitive awareness states, a photorealistic VE was created. Resulting scenes disp...
