Navigation Time Variability: Measuring Menu Navigation Errors
نویسندگان
چکیده
The subject of errors in menu studies is typically limited to reporting error rates (i.e., the number of clicks missing target items) or even completely neglected. This paper investigates menu navigation errors in more depth. We propose the Navigation Time Variability (NTV) measure to capture the total severity of navigation errors. The severity is understood as time needed to recover from the errors committed. We present a menu study demonstrating use and value of the new measure.

Gyroscope Drift Error Analysis in the Position-Independent Navigation Algorithm of a stable platform Inertial System
This paper deals with analyzing gyroscope drift error in the position-independent navigation algorithm of a stable platform inertial system. Most of the stable platform navigation algorithms proposed in the literature have drawbacks of estimating position rates for alignment commands. Not only the estimating position rates are the basic source of position errors, but they also make the alignmen...

متن کاملThe Design and Evaluation of Graphical Radial Menus
Graphical menus provide slow performance and yet users often try to select menu commands as fast as possible. Shortcut techniques that enable users to by-pass selections from a graphical menu are fast, but are not the ultimate answer to the performance problem. Shortcut techniques pose high demands on human memory. They require much training and frequent use. They do not scale well. And they of...
متن کاملGPS/INS Integration for Vehicle Navigation based on INS Error Analysis in Kalman Filtering
The Global Positioning System (GPS) and an Inertial Navigation System (INS) are two basic navigation systems. Due to their complementary characters in many aspects, a GPS/INS integrated navigation system has been a hot research topic in the recent decade. The Micro Electrical Mechanical Sensors (MEMS) successfully solved the problems of price, size and weight with the traditional INS. Therefore...
متن کاملA Hierarchical SLAM/GPS/INS Sensor Fusion with WLFP for Flying Robo-SAR's Navigation
In this paper, we present the results of a hierarchical SLAM/GPS/INS/WLFP sensor fusion to be used in navigation system devices. Due to low quality of the inertial sensors, even a short-term GPS failure can lower the integrated navigation performance significantly. In addition, in GPS denied environments, most navigation systems need a separate assisting resource, in order to increase the avail...
