“…Metaverse has been believed to blur the boundary between the physical and virtual worlds (Soliman et al ., 2017; Suh and Prophet, 2018) as well as the boundary between utility and hedonism, thus making metaverse technologies akin to dual-purposed ISs (Hamari and Koivisto, 2015; Lee and Kim, 2022; Köse et al ., 2019; Koivisto and Hamari, 2019; Kool and Agrawal, 2016; Wu and Lu, 2013). Since user acceptance is an important facet of a successfully implemented new technology (Davis, 1993; Dillon and Morris, 1996), a considerable amount of research has focused on the acceptance of the metaverse, and the TAM model is the most commonly used theoretical framework (see, e.g.…”

PurposeIn recent years, there has been significant interest in adopting XR (extended reality) technologies such as VR (virtual reality) and AR (augmented reality), particularly in retail. However, extending activities through reality-mediation is still mostly believed to offer an inferior experience due to their shortcomings in usability, wearability, graphical fidelity, etc. This study aims to address the research gap by experimentally examining the acceptance of metaverse shopping.Design/methodology/approachThis study conducts a 2 (VR: with vs. without) × 2 (AR: with vs. without) between-subjects laboratory experiment involving 157 participants in simulated daily shopping environments. This study builds a physical brick-and-mortar store at the campus and stocked it with approximately 600 products with accompanying product information and pricing. The XR devices and a 3D laser scanner were used in constructing the three XR shopping conditions.FindingsResults indicate that XR can offer an experience comparable to, or even surpassing, traditional shopping in terms of its instrumental and hedonic aspects, regardless of a slightly reduced perception of usability. AR negatively affected perceived ease of use, while VR significantly increased perceived enjoyment. It is surprising that the lower perceived ease of use appeared to be disconnected from the attitude toward metaverse shopping.Originality/valueThis study provides important experimental evidence on the acceptance of XR shopping, and the finding that low perceived ease of use may not always be detrimental adds to the theory of technology adoption as a whole. Additionally, it provides an important reference point for future randomized controlled studies exploring the effects of technology on adoption.

“…Debatably, the pictograms and logograms are devised to meet certain requirements. Driven by the smallness of screen size of modern gadgets, texters innovatively develop a set of techniques including abbreviation, graphones, word or phrase shortening, and so forth (Crystal, 2008;Gorney, 2012;Kool & Agrawal, 2016;Waldrone et al, 2016;Zappavigna, 2012). Nonetheless, Nenagh and Abbie (2017) traced 728 Australian undergraduates' textisms (from 2009 to 2015), and the findings showed a decline of textese.…”

This cross-sectional study examined the distribution of electronic texting patterns in academic writing and effects of textese on EFL learners' writing performance. It also explored teachers' perspectives on this phenomenon. Data were gleaned from 60 undergraduates enrolled for a license degree in English language and literature and 10 of their professors who were familiar with writing skills of this body of informants. A corpus of texts derived from exam scripts, assignments, and lecture notes was analyzed, and the teachers were interviewed. The results revealed that learners tend to transfer some patterns of instant messaging (IM) into their writing. However, this remains rather limited to morphosyntactic features and some other paralinguistic features and local-based contents. The phenomenon was pervasive across the sample in a descending order; learners at the entry level e-texted more than their seniors did. Besides, heavy texters used this deformed variety of English to compensate low writing proficiency in terms of spelling, word selection, and sentence structures. Additionally, texting was apparently evident in note-taking more than in answer sheets and assignments. The study concludes that textese is not a surrogate for the Standard English but an addition to it with a variance of scope and purpose of usage.

“…For audio coding, a famous demonstration at the AT&T Bell Labs in the early 1990s showed that exploiting the input signal characteristics and human auditory perception dramatically lowered the signal-to-quantizationnoise ratio required for perceptually transparent audio coding. In particular, the demonstration, which is now often referred to as the "13dB miracle" [20,21], showed that the quantization noise corresponding to a segment-wise SNR of 13 dB is inaudible if the noise spectrum is shaped according to the human auditory system. Based on this observation, the underlying hypothesis of our work is that the requirements to the TIR can be dramatically lowered if the input signal characteristic and the human auditory perception are taken into account, and we here take a first step to confirm this hypothesis.…”

The creation of sound zones has been an active research topic for approximately two decades. Many sound zone control methods have been proposed, and the best approaches result in a target to interferer ratio (TIR) of about 15 dB in a practical setup. Unfortunately, this is far from a TIR of about 25 dB which is currently believed necessary to make sound zones commercially viable. However, state-of-the-art sound zone control methods take neither the input signal characteristics nor human auditory perception into account. In this paper, we show how a recently proposed sound zone control framework called VAST can be extended into perceptual VAST (P-VAST) which takes input signal characteristics and human auditory perception into account. We also make a proof-of-concept simulation and an AB preference test which both show that P-VAST outperforms traditional sound zone control methods in terms of perceptually meaningful metrics such as STOI and PESQ in a fairly simple setup .
