Stereoscopy is commonly used in film and interactive media to provide depth perception, but is not the only method available to meet this need. This paper examines fish tank virtual reality as an alternative to stereoscopy. A study was conducted using three methods of depth perception projection: a stereoscopic image, a fish tank virtual reality (VR) image, and a combination of stereoscopic and...

Mycobacterium marinum, the cause of chronic systemic infections in fish, occasionally causes granulomatous skin and soft tissue lesions in humans. Cutaneous mycobacterial infection in two patients owing to unusual circumstances is presented in this report. The first patient was infected through improper hygienic behavior, while infection in the second patient was previously misdiagnosed as rheu...

We have developed a virtual fish tank in which computer users are represented by animated fish. The actions and interactions of the fish in the tank are meant to reflect the actions of users in the real world. Our first attempt at creating a programming environment that allowed people to customize their own fish did not work very well because users did not want to explicitly write programs to c...

Fish tank VR systems provide head coupled perspective projected stereo images on a display device of limited dimensions that resides at a fixed location. Therefore, fish tank VR systems provide only a limited virtual workspace. As a result, such systems are less suited for displaying virtual worlds that extend beyond the available workspace and depth perception problems arise when objects that ...

Lines of fish (Girardinus falcatus) obtained through selective breeding showing different degree and direction of behavioural lateralization in a variety of tasks were tested for their ability for spatial reorientation. In the first experiment, fish were required to reorient themselves after passive disorientation in a rectangular tank in the presence of a salient feature (a blue wall). Lateral...

Zebrafish in our laboratory are usually bred by removing the fish from the recirculating aquatic system and placing them into 1-2 L spawning tanks. These spawning tanks consist of a bottom reservoir, a lid, and an insert that fits in closely into the bottom reservoir. When the fish breed, the eggs fall through holes of the insert and into the reservoir, thus preventing them from being cannibali...

introduction: mycobacterium marinum infection is the most common nontuberculous mycobacterial skin lesions. it results from skin injury and contact with contaminated water, fish, or shellfish; its infections have low frequency, nonspecific symptoms and lack of specific identification methods that can alter correct diagnosis.this study designed about cases that reported from iran and comparing t...

The effects of wall color stimuli on diving, and the effects of depth stimuli on scototaxis, were assessed in zebrafish. Three groups of fish were confined to a black, a white, or a transparent tank, and tested for depth preference. Two groups of fish were confined to a deep or a shallow tank, and tested for black-white preference. As predicted, fish preferred the deep half of a split-tank over...
