How do I choose a Dino Lite microscope   We have a wide variety of different models available to suit a range of different applications. Some of the differences include magnification, resolution, type of lighting, and other hardware and software features. To help you determine the best model for your application we have made available the following resources Product Filter. Feature Comparison. Nomenclature. How do I use the Dino Lite Digital Microscope   Part A. Place the illuminated specimen on the center of the microscope stage. Always start observing using the lowest magnification with the microscope. Aim the specimen through the objective lens. Focus the microscope by slowly turning the coarse Adjustment Focus Knob, for different magnifications, until an image forms ,slowly adjust the focus back and forth to get the best focus, or to reveal hidden structure at different depths of the specimen being examined. To increase magnification, rotate the magnifications or the Objective Lens depending on the models of the Microscope 6. Focusing becomes more critical when using higher magnifications as the objective lens would need to come closer to the specimen to obtain a focus. Use the same techniques cautions in coarse and fine focusing as described above and use care so that the Objective Lens does not come in direct contact with the specimen when achieving a final focus.

The TV Video models utilize NTSC analog format which provides no delay images, whereas the USB models use a digital format which may cause a slight delay when focusing. The current Dino. Capture measurement functions have been tested by major LCD manufacturers to be within a 5 margin of error under 2. When examining LCD panels it may be necessary to apply a thin coat of oil baby oil, etc to the panel surface in order to view sub pixels. The hard coating HC applied to the LCD panel at the factory may make this necessary in order to view the pixels beyond the polarize level.

A more advanced camera model was introduced by Tsai 1986, 1987. It has become one of the most widely used camera calibration algorithms and recently found. Using multiple Dino Lite devices simultaneously on one computer   The number of simultaneous Dino Lite devices supported depends on the operating system and hardware resources, ranging from 2 to 6 devices in most cases. Windows There is no software restriction on the number of Dino Lite microscopes that can be used simultaneously. The total that can successfully be used will depend on the hardware resources of the computer. Particularly, the number of PCI USB 2. In general, most modern computers will be able to run at least two and up to six microscopes simultaneously. Mac OS The Dino. Xcope software will currently display from a maximum of four Dino Lite cameras. The total number of cameras that can successfully be used will depend on the hardware resources of the computer. Particularly, the number of PCI USB 2. If you are running Windows on top of Mac OS and want to use multiple cameras we suggest using Bootcamp rather than parallels. Trouble displaying from exactly two Dino Lite devices simultaneously This generally occurs when the device is connected to an older USB 1. USB 2. 0 port. If the device is connect to a USB hubsplitter or USB extension cable, that device may also only support the older USB 1. To resolve this issue Make sure the device is connected to a USB 2. Connect the device directly to the computer rather than through a hub or extension cable. If the device is connected to the front of the computer, try a USB port on the back of the computer. Try a different USB port Try lowering the Dino Lite display resolution certain models Lower the maximum frame rate set in the DC2. Trouble displaying from more than two Dino Lite devices simultaneously When trying to use three or more Dino Lite microscopes simultaneously on one computer all microscopes light up, but some show only a black screen in the software. Possible causes include Most common Windows Mac A PCI USB Controller This issue most likely indicates that the PCI USB controller does not have enough bandwidth for all the microscopes. If the computer has multiple USB controllers such as one group of USB ports in the front and one in the back of the computer, try to distribute the Dino Lites evenly among the USB controllers. If there is only one USB controller installed, you may need to add another PCI USB controller in order to run three or more microscopes. B Video Memory If distributing the Dino Lite microscopes evenly among the PCI USB controllers does not solve the problem, another possiblity may be that the computer does not have enough graphics memory to support multiple cameras especially if the computer has integrated graphics. In this case, you may need to add a discrete graphics card or upgrade the graphics card. C USB hub or different ports Sometimes connecting some or all of the Dino Lites to a USB hub or different USB ports can help resolve this issue. If using a USB hub, ensure it is at least a USB 2. Mac OS Windows Virtualization D Bootcamp not Parallels If you are running Windows on top of Mac OS and want to use multiple cameras we suggest using Bootcamp rather than Parallels. Other possible resolutions. Make sure the device is connected to a USB 2. Connect the device directly to the computer rather than through a hub or extension cable. If the device is connected to the front of the computer, try a USB port on the back of the computer. Try a different USB port. Try lowering the Dino Lite display resolutioncertain models Lower the maximum frame rate set in the DC2. Uninstall other web cam type devices which may potentially conflict with the Dino Lite.

Alyze a MATLAB toolbox for the analysis of eye movement data. In recent psychophysiological research, eye tracking methodology has been widely used to obtain reaction parameters from eye movement data to analyze cognitive processes underlying visual behavior. Eye movements are classified into two basic components the movements of the eye itself called saccades and the times between movements when the eye remains in a single position called fixations. Fixations typically occur only with the reception of sensory information, and vision is generally suppressed during saccades Matin, 1. Eye movements are closely linked to visual attention therefore, many studies have used the analysis of saccadic target regions to investigate the link between eye movements and covert attention. Some of these studies have shown that attention is always oriented in the same direction as saccades Deubel Schneider, 1. Hoffman Subramaniam, 1. Irwin Gordon, 1. Kowler, Anderson, Dosher, Blaser, 1. Others have shown that attention and eye movements can be dissociated Awh, Armstrong, Moore, 2. Hunt Kingstone, 2. A recent article Golomb, Marino, Chun, Mazer, 2. Other studies have investigated situations in which multiple objects must be tracked and have found that eye gaze is directed more toward the centroid of the target group than to any single target Fehd Seiffert, 2. Huff, Papenmeier, Jahn, Hesse, 2. The relationship between attention and eye movements has also been discussed in some literature reviews Rayner, 2. Theeuwes, Belopolsky, Olivers, 2. Research into visual behavior is motivated by applied psychological questions the main topics of such research include the processing of facial expressions in social cognition Brassen, Gamer, Rose, Buchel, 2. Domes et al., 2. 01. Gamer, Zurowski, Buchel, 2. Liu et al., 2. 01. Stigchel, Imants, Richard Ridderinkhof, 2. Cho Thompson, 2. Myung et al., 2. Eye movement data must undergo a principal processing pipeline including the following modules. The first module is preprocessing, such as blink detection and filtering. The second module is an event detection of patterns in eye movement, such as fixations and saccades. The third module is the generation of analysis parameters from these events for further statistical analysis. Finally, the fourth module includes different visualization and stimulus overlay techniques of the eye movement data, such as heat maps and gaze plots. In addition to this main data processing queue, there is also the separation of visual stimuli regions of interest ROIs, in case these subregions have special psychological meanings. While this processing queue has largely remained consistent since the beginning of eye tracking research, the analysis paradigm can be further developed Some of these different approaches to eye movement data processing are mentioned below. There exist various methods for detecting events in the raw data, such as algorithms for blink detection Morris, Blenkhorn, Farhan, 2. Blignaut, 2. 00. 9 Nystrom Holmqvist, 2. Salvucci Goldberg, 2. Widdel, 1. 98. 4, and saccade detection Fischer, Biscaldi, Otto, 1. The analysis of eye movement in response to dynamic visual stimuli and dynamic ROIs Papenmeier Huff, 2. Reimer Sodhi, 2. Some researchers have focused on the model based analysis of the eye tracking data to explain sequences of eye movement patterns with assumptions for underlying cognitive models. Goldberg Helfman, 2. Salvucci Anderson, 2. The present article presents the software Gaze. Alyze, a MATLAB toolbox for the offline batch analysis of eye tracking data. Gaze. Alyze was developed to analyze gaze data for static visual stimuli and to obtain parameters from fixations and saccades for further visualization and statistical analysis. Gaze. Alyze is suitable for application in research on visual attention in the cognitive processing of visual stimuli and for measurement of volitional control of behavior that is sensitive to fronto striatal dysfunction, such as the antisaccade task. Gaze. Alyze can utilize various algorithms according to choice and is an open source software Users can change and extend analysis steps. Gaze. Alyze is a universal analysis software and includes import capabilities for different eye tracking data types and, therefore, is useful for data pooling. Gaze. Alyze also includes features of data quality analysis and artifact control, such as reports of global and trial wise validation parameters or correction strategies to handle scan path drifts in fixed head settings. Gaze. Alyze stores the experimental settings in study related control scripts for easy overview and editing. Our intent was to design an application that allows the management of the entire offline processing and analysis of eye movement data containing capabilities such as extendibility, universality, and quality control, as well as batch processing of file sets. Gaze. Alyze uses modules for blink detection, filtering, and event detection from ILAB 3. Gitelman, 2. 00. 2, a MATLAB toolbox for processing eye movement data. The Gaze. Alyze data structure can also be loaded into the ILAB software. Gaze. Alyze mainly expands the capabilities of ILAB by providing the following utilities the batch processing of data file sets, the analysis and export of detected eye movement events such as fixations and saccades, and visualization capabilities in the form of heat maps. Besides ILAB, other free open source software tools are available for offline eye movement analysis. There are two freeware tools programmed in C, which run only on Windows computers. A very well designed application is OGAMA Vosskuhler, Nordmeier, Kuchinke, Jacobs, 2. Structured Query Language SQL database. The other C based software is ASTEF Camilli, Nacchia, Terenzi, Di Nocera, 2. Index as a measure of the spatial dispersion of the fixation distribution.
