dc.description.abstractAccurate location information in a mobile map application is imperative within specialized domains like agricultural field research where users often carry out location-finding tasks. This is particularly relevant in agricultural research where field plots are small and similar in visual appearance. Location inaccuracy can result in difficulties determining the exact location of a target plot, leading to increased time and manual effort for plot identification. While smartphone map applications are widely used for wayfinding, GPS accuracy may not be sufficient for location-finding tasks in agricultural contexts, especially when the error in location accuracy equals or exceeds the size of the target plot. There is little known about smartphone GPS reliability and user experience during these tasks, and how inaccuracy affects user performance and trust in location information for agricultural field research tasks. This thesis investigates the effects of GPS accuracy on the usability of a map application for finding locations in agricultural field research. Two empirical studies were conducted to evaluate smartphone GPS accuracy and the influence of error rates on user performance and trust in the system while performing location-finding tasks in an agricultural field research scenario. The results from these studies establish a direct correlation between high error rates and diminished performance, resulting in reduced trust in the provided location information. Additionally, the results highlight various strategies employed to mitigate the reduced accuracy. This new knowledge can improve user experience in location-based applications through the implementation of best practices to provide better user support.
