VStarcam C7824WIP HD ($50USD)

The VStarcam C7824WIP HD looked to be interesting.  However, seems to be lacking in a few categories including the picture quality which is blurry and also seems to be limited to 640x400 through the web interface. Might be interesting for research/education - as has motion for Pan:270°,Tilt:80°; night vision; GPIO (in the web interface -- nothing showing on the outside). Also, need to look at the security of these devices.  As Vint Cerf says, he fears the headline "Bank of America attacked by networked fridges" [paraphrased].

This is the image quality -- taken using the motion detection sent to email (640x400) using the night vision.  

The Visualization Studio at the University of Calgary has a VisWall with 34.5 million pixels for a resolution of 9600x3600.  It is 16 feet by 6 feet. The following are some visualizations we just explored using this technology.

About the Visualization Studio:
https://library.ucalgary.ca/faculty-instructor-support/visualization-studio

Publication Dashboard - The following image shows a Publication dashboard generated from the Synthesis literature review software. The top section displays the publication titles on a timeline.  The bottom section shows a variety of aggregated data such as author associations, journal by country (bar, pie, line, stacked bar, etc), and journal by year frequency (treemap). Two visualizations were displayed - Overview of the Canadian Community Health Survey and Overview of Ebola publications.

Forest Ranger - The following visualization shows an automated analysis of the Canadian Community Health Survey. Since there are hundreds of Forest Plots showing the association between outcome and exposure, the VisWall is a good medium for displaying all this data.  When a association looks interesting it can be expanded on the right side of the VisWall. The software that generated these forest plots is called ForestRanger.  

Verbal Autopsy - The following visualization is displaying a Decision Tree based upon the WHO Verbal Autopsy (VA) questionnaire. The VA questionnaire is 17 pages in length and the goal of this project is to establish a 20 question system in which the questions are asked. At present there are 4,000 pathways (sequence of questions) in this decision tree.  

Forest Ranger (2014) - ForestRanger is an application for visualizing large amount of Forest Plots generated from cross sectional surveys (i.e. Canadian Community Health Survey - CCHS).  The Forest Plot(s) report on the association between outcome and exposure variables (i.e. Stroke versus Hypertension adjusted by sex and age) broken down by survey year (i.e. 2008, 2007, 2006, 2005, etc.).  For a chronic disease series of reports there could be 20 variables reported on which would correspond to approximately 400 charts.  ForestRanger allows a researcher to quickly see which associations are increasing or decreasing or have the greatest Odds Ratios (OR) of the associations.  The researcher can then click on the chart of interest and the larger report appears on the right hand side.  ForestRanger can be used for visualizing any directory of PDFs.
