The application works by pointing a smartphone or a wrist- worn sensor kit towards a physical venue location of interest. By retrieving information about the venue pointed at over various APIs, the application presents these to the users via high quality text-to-speech synthesis, negating the need to interact with the smartphone, which can be kept in a user{\textquoteright}s pocket at all times. Here, we discuss the implementation details of our prototype and outline future research directions.}, keywords = {gestural interaction, location based services, multimodal interaction, wrist sensors}, doi = {10.1109/PERCOMW.2018.8480136}, author = {Andreas Komninos and Stylianos Sarakinos and Lydia Marini and John Garofalakis} }
