In this project, we aim to develop and evaluate displays of automation uncertainty that aid in the transition of control from automated to manual driving. Currently, we are focused on two manipulations of these displays. The first manipulation, metric, is manipulated by presenting system reliability information (Reliability) or the level of engagement necessary for the driver (Required Driver Engagement, RDE). The second manipulation, modality, is manipulated by presenting the information visually, auditorily, or with a combination of visual and auditory information (multimodal).

This project will bring together the static (e.g., sidewalk condition, street networks, characteristics of land use) and dynamic (e.g., traffic volumes, weather, and light quality) characteristics of the environment that are monitored close to real time into one decision support system for route planning.

Text messaging is a functionality that has been widely used in user studies due to its presence in smartphones and feature phones alike. However, the ability to use cell phones for data collection has been limited to researchers that have programming abilities. We present SMSPress, a web-based SMS management system that allows non-technical users to configure SMS studies, and schedule text messages for delivery to participants via a web-interface. We establish the requirements for such a system and present the results from two case studies.
