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...

Displays are ubiquitous in modern life, and there is a growing need to develop active, full color, video-rate reflective displays that perform well in high-light conditions. The core of display technology is to generate or manipulate light in the visible wavelength. Colored fluids or fluids with particles can be used to tune the light intensity (greyscale) or wavelength (colors) of reflective d...

A digital imaging system was developed for measuring various physical characteristics of individual nematodes and for comparing groups of nematodes. The equipment consists of a microscope, a video camera, a video digitizer, interactive displays, and a computer. Various physical and mathematical methods were incorporated, algorithms devised, and computer software written for image acquisition, e...

A challenging task when designing a video server is to support the performance criteria of its target application i e both its desired number of simultaneous displays and the waiting tolerance of a display With a multi disk video server the placement of data has a signi cant impact on the overall performance of a system This study quanti es the tradeo s associated with alternative organization ...

This paper proposes the chart−style video playback interface PlayWatch; it displays a chart of semantic indices for locating video scenes. The main features of PlayWatch are: 1) the user understands the distribution of the scenes because PlayWatch shows the indices in order. 2) The user can access a desired scene directly through the indices since they also act as link buttons. This paper also ...

Displaying broadcast video on a MultiMedia PC, implies the use of video format conversion (VFC) techniques, as computer displays and television receivers use quite distinct scanning rasters. VFC consists of spatial scaling, deinterlacing and picture rate conversion. Although scaling is rather straightforward, the other two tasks are far from trivial, and advanced motion compensated interpolatio...

Tutorials are one of the most fundamental means of conveying knowledge. Ideally when the task involves physical or digital objects, tutorials not only describe each step with text or via audio narration but show it as well using photos or animation. In most cases, online tutorial authors capture media from handheld mobile devices to compose these documents, but increasingly they use wearable de...

background: video-based instruction has been stated as an effective method of teaching and its potentials have encouraged instructors learners to opt this method purpose: the current study has compared the students' cognitive learning in the two approaches of lecture- based and video-based teaching. methods: this quasi-experimental study was conducted on 88 senior nursing students who were rand...

One of the most promising and challenging future uses of head-mounted displays (HMDs) is in applications where virtual environments enhance rather than replace real environments. To obtain an enhanced view of the real environment, the user wears a see-through HMD to see 3D computergenerated objects superimposed on his/her real-world view. This see-through capability can be accomplished using ei...

AIM The aim of this study is to examine emotional processing of infant displays in people with Eating Disorders (EDs). BACKGROUND Social and emotional factors are implicated as causal and maintaining factors in EDs. Difficulties in emotional regulation have been mainly studied in relation to adult interactions, with less interest given to interactions with infants. METHOD A sample of 138 wo...
