A TV minimization strategy incorporated into commonly used PET reconstruction algorithms was useful for reducing the occurrence of artifacts due to gaps between detector modules in small-diameter PET scanners.
Reading is central to learning and communicating, however, divided attention in the form of distraction may be present in learning environments, resulting in a limited understanding of the reading material. This paper presents a novel system that can spatio-temporally detect divided attention in users during two different reading applications: typical document reading and speed reading. Eye tracking and electroencephalography (EEG) monitor the user during reading and provide a classifier with data to decide the user's attention state. The multimodal data informs the system where the user was distracted spatially in the user interface and when the user was distracted. Classification was evaluated with two exploratory experiments. The first experiment was designed to divide the user's attention with a multitasking scenario. The second experiment was designed to divide the users attention by simulating a real-world scenario where the reader is interrupted by unpredictable audio distractions. Results from both experiments show that divided attention may be detected spatiotemporally well above chance on a single-trial basis.
This paper investigates the concept and development of Bio-Sonic Sense, an artistic interpretation of bio sonars, as an attempt to create a cross-species experience. It examines the potential of sensory transformation through technology-specifically, transcoding visual to audio-with the purpose of communicating the mechanisms of ultrasonic communication employed by marine mammals. Bio-Sonic sense is the result of using artistic practice and critical play, in order to disseminate the effects of noise pollution on marine life. This paper proposes that those practices should be explored as methods that can design for the use of technics as tools that can expand the human senses, thus allowing the exploration of non-human "worlds".
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
