Speed-Dependent Automatic Zoom Interface
By: Maj. IP Krepps
Supervisor: Mr. G. Phillips
Abstract
The current implementation of pan and zoom techniques in digital map based command and control applications suffer from numerous usability problems. Over the past several years, a number of alternative view manipulation techniques have been proposed. A technique known as speed-dependent automatic zoom, which integrates pan and zoom tools into a single integrated action demonstrates significant potential. Based on previous speed-dependent automatic zoom research, a variable floor interface was developed. A usability experiment was conducted to compare the performance of the speed-dependent automatic zoom interface with a traditional pan and zoom interface. Experimental results clearly demonstrate the overall superior performance and user preference for the speed-dependent automatic zoom interface. Implications from these findings show that a map based command and control application would benefit significantly from a speed-dependent automatic zoom map interface.
