Measurement of users' perception and visual behaviors to anthropomorphic design cues chatbots can improve our understanding potentially optimize chatbot design. However, as two typical basic features, how appearances conversational styles jointly affect remains unclear. Therefore, this study conducted an eye-tracking experiment explore behaviors. Results indicate that human-like increased chatbots' social presence, trust in chatbots, satisfaction with chatbots. In contrast, on behaviors,...

This study investigates how the sound of a hair dryer influences users’ perceptions its quality, using functional near-infrared spectroscopy (fNIRS) to measure prefrontal cortex (PFC) activation. Eighteen participants were involved in within-subject evaluation experiment where they assessed perceived quality dryers with three different levels: no sound, low and high sound. The results show that levels rated as having higher caused greater increases oxygenated hemoglobin (HbO) concentration...

Numerous studies have emerged on the external human–machine interface (eHMI) to facilitate communication between automated vehicles (AVs) and other road users. However, it remains be determined which eHMI modality location are proper for pedestrian–AV interaction. Therefore, a video-based, eye-tracking study was performed investigate how pedestrians responded AVs with eHMIs in different modalities (flashing text, smiley, light band, sweeping pedestrian icon, arrow, bar) locations (grill,...

Abstract To improve the interaction between drivers and in‐vehicle information system (IVIS), various intelligent agents, such as robot virtual voice‐only have been integrated into vehicles. However, it is not yet clear which type of agent best suited to driving context. This study aims investigate effect embodiment on drivers' perceived usability cognitive workload. In a within‐subject simulated experiment, 22 participants interacted with three different agents (smartphone agent, agent)....

Generating kansei profiles for products represent fundamental aspects of engineering (KE). Conventionally, the semantic differential (SD) method has been extensively employed to construct product profiles, aiming delve into consumers’ perceptions products. However, this approach is associated with significant time consumption and inefficiency. In light this, we introduce an innovative evaluation that incorporates preferences, thereby enhancing efficiency process. This comprises three...

Assessing design solutions via domain-specific emotions has been widely concerned and explored in the field of affective design. However, examination accommodation individual differences have not settled sufficiently literature. To address this research gap, paper proposes a descriptive approach to draw calibrated collective emotion patterns survey-based assessment. A 'Repertory Grid Interview linked with Rate-All-That-Apply' (RGI/RATA) procedure is firstly conducted elicit code individual's...

Human-robot touch interaction plays an essential role in emotional support and human mental health support. The of therapeutic robots such as Paro has been widely investigated. However, the impact humanoid robotic on social regulation users' emotions is still unknown. Therefore, a mixed experiment was conducted with type (grip versus contact) between-subjects factor presence during movie reception (with without touch) within-subjects factor. subjective perception emotion, ECG, fNIRS signals...

Recently in ergonomics and human factors community, there have been calls for incorporating affective aspects, such as pleasure aesthetics, product development. This study presents a systematic approach to modelling Kansei, which is users' subjective feeling impression, by combining variable precision rough sets (VPRS) association rule mining. The design element reducts corresponding each Kansei attribute are firstly extracted using β-partition quality-based reduction algorithm....

AbstractThe present study aimed to investigate how facial features, including ratio, eye shape, and mouth presence, influence users’ perceptions of social robots in terms anthropomorphism, trustworthiness, overall impressions. Using electroencephalogram (EEG) eye-tracking technologies, we conducted a 2 (face ratio) × (eye shape) (with or without mouth) full factorial experiment designed within-subject. EEG signals pupil diameters were recorded while participants viewed images with different...
