In this paper we discuss augmented reality (AR) displays in a general sense, within the context of reality-virtuality (RV) continuum, encompassing large class `mixed reality' (MR) displays, which also includes virtuality (AV). MR are defined by means seven examples existing display concepts real objects and virtual juxtaposed. Essential factors distinguish different systems from each other presented, first table nature underlying scene, how it is viewed, observer's reference to compared,...

A number of properties—aptness, topic-vehicle similarity, vehicle conventionality—have recently been used to explain a metaphorsi-mile distinction. This paper argues that interpretive diversity better explains metaphor-simile distinction than these properties. Interpretive refers the semantic richness figurative interpretation pair and is determined depending on both features involved in uniformity salience distribution those features. The view predicts interpretively more diverse pairs...

Recent metaphor research has revealed that comprehension involves both categorization and comparison processes. This finding triggered the following central question: Which property determines choice between these two processes for comprehension? Three competing views have been proposed to answer this conventionality view (Bowdle & Gentner, 2005), aptness (Glucksberg Haught, 2006b), interpretive diversity (Utsumi, 2007); views, respectively, argue vehicle conventionality, aptness, determine...

A hearer's perception of an utterance as sarcastic depends on integration the heard statement, discourse context, and prosody utterance, well evaluation incongruity among these aspects. The effect in sarcasm comprehension is evident everyday conversation, but little known about its underlying mechanism or neural substrates. To elucidate underpinnings auditory modality, we conducted a functional MRI experiment with 21 adult participants. participants were provided short vignette which child...

Abstract The pervasive use of distributional semantic models or word embeddings for both cognitive modeling and practical application is because their remarkable ability to represent the meanings words. However, relatively little effort has been made explore what types information are encoded in vectors. Knowing internal knowledge embedded vectors important using models. Therefore, this paper, we attempt identify by conducting a computational experiment Binder et al.'s (2016) featural...

By applying network robot technologies, recommendation methods from E-Commerce are incorporated in a retail shop the real world. We constructed an experimental environment where communication robots recommend specific items to customers according their purchasing behavior as observed by networked sensors. A scenario is implemented with three and investigated through experiment. The results indicate that participants stayed longer front of shelves when tried interact them were influenced...

Previous metaphor studies have paid much attention to nominal metaphors and predicative metaphors, but little has been given adjective metaphors. Although some focused on they only examined differences in the acceptability of various types This paper explores cognitive effects evoked by Three psychological experiments revealed that (1) especially those modified color adjectives, tend evoke negative effect; (2) although meanings are basically affected their vehicles, when a vehicle neutral...

This paper presents a unified theory of verbal irony for developing computational model irony. The claims that an ironic utterance implicitly communicates the fact its situation is surrounded by environment which has three properties, but hearers can assume to be even when they recognize it only two properties. Implicit communication properties accomplished in such way alludes speaker's expectation, violates pragmatic principles, and implies emotional attitude. also describes method...

Some people have difficulty participating in social activities due to COVID-19 or other factors such as age, physical cognitive state, appearance, and gender hindrance. We propose a concept of active participation with cybernetic avatars (CAs) that are tele-operated robots CG agents. also the CA platform, which is software platform connects CAs tele-operators, make it easier for various locations participate society using CAs. In this paper, we three types connection methods environment...

A number of studies on network analysis have focused language networks based free word association, which reflects human lexical knowledge, and demonstrated the small-world scale-free properties in association network. Nevertheless, there been very few attempts at applying to distributional semantic models, despite fact that these models studied extensively as computational or cognitive knowledge. In this paper, we analyze three properties, namely, small-world, scale-free, hierarchical...

A dominant theory of humor comprehension suggests that people understand by first perceiving some incongruity in an expression and then resolving it. This is called "the incongruity-resolution theory." Experimental studies have investigated the neural basis comprehension, multiple substrates been proposed; however, specific substrate for resolution still unknown. The reason may be phase, despite its importance has not successfully distinguished from perception phase because both phases occur...

In this article, we address the problem of how people understand predicative metaphors such as "The rumor flew through office," and argue that are understood indirect (or two-stage) categorizations. categorization process, verb (e.g., fly) a metaphor evokes an intermediate entity, which in turn metaphoric category actions or states "to spread rapidly soon disappear") to be attributed target noun rumor), rather than directly evoking argued by Glucksberg's (2001) Glucksberg, S. 2001....

We examined whether a machine-learning-based automated scoring system can mimic the human similarity task performance. trained bidirectional encoder representations from transformer-model based on semantic test (SST), which presented participants with word pair and asked them to write about how two concepts were similar. In Experiment 1, fivefold cross validation, we showed model combination of responses (N = 1600) classification criteria (which is rubric SST; N 616) scored correct labels...

This study examines the ability of nonnegative matrix factorization (NMF) as a method for constructing semantic spaces, in which meaning each word is represented by high-dimensional vector. The performance two tests (i.e., multiple-choice synonym test and association test) compared between NMF latent analysis (LSA), most popular spaces. As result, it was found that did not outperform LSA either test. finding indicates less effective acquiring meanings than expected literature; other words,...

This lack understanding particularly problematic when vectors are regarded as model representation abstract concepts. paper attempts reveal internal by analysis using Binder et al.'s (2016)...

Automated driving and auxiliary functions are expected to improve safety efficiency, reduce the burden on drivers. These assist change task of driver not control vehicle but monitor operation, which could lead new kind stress. In this paper, stress during automated follow-up is evaluated based subjective evaluation physiological measurement in a simulator environment. We confirmed that anxiety due acceleration / deceleration intensity varies depending inter-vehicle distance.
