Beyond the Bezel: Utilizing Multiple Monitor High-Resolution Displays for Viewing Geospatial DataLuebbering, Candice Rae 11 June 2007 (has links)
Computers have vastly expanded capabilities for storing, creating, and manipulating spatial data, yet viewing area is still generally constrained to a single monitor. With this viewing window limitation, panning and zooming are required to view the full details of a map or image and, because of the large sizes of typical database, usually only in small portions. Multiple monitor configurations provide an attainable, low cost way for individuals to create large, high-resolution desktop displays. This increased screen real estate is particularly useful for viewing and interpreting rich and complex geospatial datasets because both context and amount of detail can be simultaneously increased, reducing reliance on virtual navigation to obtain the desired balance between context and scale. To evaluate the utility of multiple monitor displays for geospatial data, this experiment involved a variety of map and image reading tasks using both raster and vector data under three different monitor conditions: one monitor (1280 x 1024 pixels), four monitors (2560 x 2048 pixels), and nine monitors (3840 x 3072 pixels). Fifty-seven subjects took the test on one of the three display configurations. A computer program captured each subject's performance by recording answers, mouse click locations, viewing areas, tool usage, and elapsed time. A post-experiment questionnaire obtained additional qualitative feedback about subjects' experience with the tasks and display configuration. Overall, subjects did perform more efficiently on the larger display configurations as evidenced by a reduction in test completion time and in the amount of virtual navigation (mouse clicks) used to finish the test. Tool usage also differed among monitor conditions with navigation tools (zooming and panning) dominating on the single monitor while selecting tools (tools used to provide answers) predominated on the nine monitor display. While overall test results indicated the effectiveness of the larger displays, task-level analyses showed that specific performance varied considerably from task to task. The larger displays were the most efficient on some tasks, while other tasks showed similar results among all displays or even the single monitor as the most efficient. The best performance improvements occurred between the one and four monitor conditions, with the nine monitor condition mostly providing only modest additional improvement. Subjects rated the four monitor display size as the most ideal. / Master of Science

Lagringsmätning för AD-information / Measurement Storage for AD-informationIshak, Michel January 2012 (has links)
Målet med detta projekt var att hjälpa IT-Mästaren att kunna fakturera sina kunder på ett smidigare sätt. Deras dåvarande lösning av kundernas dataanvändning var tidskrävande och ineffektivt, därför ville de automatisera systemet. Det nya systemet skulle användas för att administrera kundernas servrar med hjälp av ett grafiskt gränssnitt och sedan kontakta dem för att få fram olika värden för respektive kund som ska presenteras på IT-Mästarens hemsida. På så sätt skulle de kunna fakturera sina kunder på ett mer effektivt sätt och även få bättre överblick av kundernas användning. I och med utvecklingen utav detta system så fördjupande jag mig dels i egna kända områden men jag lärde mig också nya kunskaper. Det gällde inte enbart teknisk utveckling utan också undersökning av exempelvis hämtningen av alla data som skulle göras. Jag använde utvalda metoder för att kunna utföra detta projekt på ett smidigt och bra sätt. Metoderna beskrivs i rapporten. / The goal of this project was that the IT-Mästaren wanted to be able to bill their customers in a more comfortable way. Their solution of the customer’s server usage of that time was time consuming and inefficient, therefore they wanted to automate the system. The new system should manage their customer’s servers by using a graphical interface and then contact them to get different values for each customer to be presented at the IT-Mästaren's website. In this way they could bill their customers more efficiently and get a better understanding of their customers’ use. With the development of this system I immersed in my own known areas and I also learned new knowledge. It was not only about technical development but also investigationamong other thingslike retrieval of all the data that should be collected. I used selected methods in order to perform this project in a smooth and effective manner. The methods are described in the report.
