“…The mental arithmetic task was designed to cause mental workload (MWL) based on previous studies ( So et al, 2017 ; Jost et al, 2019 ) and was divided into two task levels: low- and high-MWL. The low-MWL task consisted of easy questions involving single-digit addition and subtraction (i.e., 3+2, 4–1, with numbers ranging from 1 to 9).…”

The aim of this study was to determine the effect of heartbeat-evoked potentials (HEPs) on the performance of an event-related potential (ERP)-based classification of mental workload (MWL). We produced low- and high-MWLs using a mental arithmetic task and measured the ERP response of 14 participants. ERP trials were divided into three conditions based on the effect of HEPs on ERPs: ERPHEP, containing the heartbeat in a period of 280–700ms in ERP epochs after the target; ERPA-HEP, not including the heartbeat within the same period; and ERPT, all trials including ERPA-HEP and ERPHEP. We then compared MWL classification performance using the amplitude and latency of the P600 ERP among the three conditions. The ERPA-HEP condition achieved an accuracy of 100% using a radial basis function-support vector machine (with 10-fold cross-validation), showing an increase of 14.3 and 28.6% in accuracy compared to ERPT (85.7%) and ERPHEP (71.4%), respectively. The results suggest that evoked potentials caused by heartbeat overlapped or interfered with the ERPs and weakened the ERP response to stimuli. This study reveals the effect of the evoked potentials induced by heartbeats on the performance of the MWL classification based on ERPs.

Wireless virtual reality integrated multidisciplinary technology, combined with related industries and fields, has changed the way of human-computer interaction and opened up a new field of user experience. In recent years, with the rapid improvement of computer technology and hardware conditions, interactive technology has developed rapidly. The existing wireless virtual reality interactive system is too single and cannot be used in multiple environments. The original system requires a large number of sensor equipment, the cost is high, and the traditional perception technology is too restrictive and cannot realize human-computer interaction more naturally. This paper proposes a dual intention perception algorithm based on the fusion of touch (obtained by experimental simulation equipment), hearing, and vision. The algorithm can perceive the user’s operation intention through the user’s natural behavior and can identify the user’s two intentions at the same time. This paper proposes a navigational interactive mode, which provides users with multimodal intelligent navigation through intelligent perception of user intent and experimental progress. We determine the impact model of the interactive system effect evaluation and analyze its effect evaluation strategy in depth and then further quantify the indicators under the four effect dimensions of information perception, artistic reflection, social entertainment, and aesthetic experience. A combination of qualitative and quantitative methods was used to carry out relevant research on effect evaluation, usability test, and questionnaire interview. The experimental results show that this interactive system has better entertainment effects than other forms of film and television animation, but still needs to pay attention to and strengthen the construction and embodiment of film and television animation content, as well as the optimization and perfection of the fault-tolerant mechanism in the design process.

“…there might be no reference system), the balancing process applies to every game utilised for game elicitation. Reasons for this are the inherent interaction design and visualisation components of a game that influence humans' cognitive resources during the play activity [25]. Hence, another layer -the interaction layer (IL) -emerges in the design process as mapping GL to SL requires designed abstraction from real-world interaction in an STS.…”

Socio-technical systems are creating work environments that are data-driven and real-time oriented. While algorithms can assist in this complex environment, decision making still predominantly relies on humans. An inadequate presentation of information and limited conception of decision outcomes are thereby potential sources of human error. Misperceptions of feedback and time-delayed effects, for example, contribute to the bullwhip effect observed in supply chains. In this case study, we applied the novel approach of game elicitation (GE) to explore human-centred assistance strategies for delayed-effect decision making. We designed a gaming simulation of a supply chain shortage incident to observe four logistics experts and four non-experts trying to balance the distribution system. Qualitative content analysis of thinking aloud protocols and reflective interviews yielded design suggestions for data presentation, monitoring, and learning regarding delayed-effect decisions. Findings suggest applicability in further domains of digital society, such as privacy decision making.
