ItemSituational Awareness and Systems for Driver-Assistance( 2017-01-04)Low level of driver’s situation awareness (SA) and high level of cognitive load are considered as reasons of vehicle accidents. Cognitive load is higher when driving abroad because of unfamiliarity with differences in international traffic rules or vehicle configurations. This paper aims to objectively assess the driver’s SA when performing lane changing tasks under unfamiliar driving conditions. We conducted an experiment using a right-hand driving simulator and a left-hand simulated traffic scenario to collect the temporal information about SA such as time, location, and speed as well as lane changing errors. Overall, the participants show low SA in curved roads and road networks, but high SA in straight roads. The results state that speed does not affect the lane changing performance on straight roads and road networks but significantly affects the lane changing performance on curved roads. These findings can be used to design a SA system for driver-assistance in unfamiliar driving conditions considering drivers’ cognitive load.
ItemShopWithMe!: Collaborative Information Searching and Shopping for Online Retail( 2017-01-04)We present research on the development and evaluation of a collaborative search and shopping system for online retail tasks based on domain specific product requirements. We describe the design rationale for the system development and inclusion of collaborative features, including search, chat, clip-board, product suggestions, shared views, and shopping cart with a focus on how these features are used for collaborative online retail shopping and information searching and sharing. Our research goal is to understand whether collaborative search tools are useful in supporting actual collaborative online retail shopping tasks for experience goods. We describe system development and report findings from preliminary user studies of the system, using mixed methods analysis, with an emphasis on the qualitative findings. The findings highlight that systems for the online shopping domain can support searching, shared views, and group communication to aid in collaborative shopping for experience goods by improving information sharing among group members. Implications are that ecommerce systems, websites, and web apps should support collaboration based on product types.
ItemA Context-Aware Mobile Solution for Assisting Tourists in a Smart Environment( 2017-01-04)The cultural heritage of the italian territory is an impressive breadth of resources, unfortunately still little known today. Such a cultural heritage should be valued for the purpose is to better understand the Italian citizens their cultural identity, is to make known to the citizens of other nations the history of the place, with its story and its characters, and the life of the inhabitants, with their own traditions and customs. \ \ In this paper, it is introduced an adaptive Context-Aware app able to collect not-structured data, belonging to heterogeneous sources and develop tailored recommendations for the user, in order to support a tourist inside a town. The solution found takes advantage of information technologies, like Internet of Thing and Internet of Services and the objective is reached through the use of a system of description of the context through a graphical formalism named Context Dimension Tree. \ \ The system described was implemented in the city of Salerno in Italy and the results of a questionnaire distributed to the users show great appreciation.
