Determinants of player acceptance of mobile social network games: An application of extended technology acceptance model

In recent years, mobile devices and social network games (SNGs) have gained wide popularity among the mainstream users. The present study aims to investigate the psychological elements that may contribute to user behaviors regarding mobile-social network games (M-SNGs). This study introduces an integrated model for M-SNGs. Statistical results from an online survey of players of M-SNGs indicate that the proposed research model effectively demonstrates and examines player acceptance of and attitudes toward M-SNGs. This research model is valid, and illustrates not only perceived enjoyment and usefulness as determinant variables of intention to use among players, but also perceived mobility together with perceived control and skill as motivational factors for players. The results also describe that satisfaction has a moderate role, which in turn has significant effects on multiple connections in the research model. Both theoretical and practical implications are provided based on the findings.

An Integrated Adoption Model of Mobile Cloud Services: Exploration of Key Determinants and Extension of Technology Acceptance Model

This study identifies and investigates a number of cognitive factors that contribute to shaping user perceptions of and attitude toward mobile cloud computing services by integrating these factors with the technology acceptance model. A structural equation modeling analysis is employed on data collected from 1099 survey samples, and results reveal that user acceptance of mobile cloud services is largely affected by perceived mobility, connectedness, security, quality of service and system, and satisfaction. Both theoretical and practical implications of the studys findings are discussed.

The effects of screen-size and communication modality on psychology of mobile device users

Does screen-size matter in mobile devices? There appears to be a move toward larger screens, with recent launches of Apples iPad and Samsungs Galaxy Tab, but do these devices undercut the perceived mobility and affect user attitudes toward the technology? To answer these and related questions, the present study examines the effects of screen-size and communication modality (text vs. video) on mobile device users perception of mobility and content as well as attitudes toward technology acceptance. Preliminary data from a between-subjects experiment show that smaller screen-size elicited greater perceived mobility while larger screen-size was key to greater enjoyment. News story in video format played a crucial role in providing greater enjoyment and newsworthiness of the news story while news in text format was perceived to be easier to use on a mobile device. Design implications and limitations are discussed, as we prepare for a constructive replication.

User acceptance of long‐term evolution (LTE) services: An application of extended technology acceptance model

Purpose – The aim of this paper is to propose an integrated path model in order to explore user acceptance of long‐term evolution (LTE) services by examining potential causal relationships between key psychological factors and user intention to use the services.Design/methodology/approach – Online survey data collected from 1,344 users are analysed with the structural equation modelling (SEM) method.Findings – Results reveal that satisfaction is the most crucial factor contributing to user intention to use LTE services. Other factors, including perceived usefulness, attitude, and system and service quality, also have notable impacts on user intention. Furthermore, system and service quality is affected by both perceived processing speed and perceived mobility, while perceived usefulness is primarily influenced by perceived adaptivity. In addition, four factors (perceived usefulness, adaptivity, processing speed, and system and service quality) are found to be major determinants of the user attitudes towar...

Factors influencing users' employment of mobile map services

This study introduces an integrated research model to examine user acceptance of mobile map services, hypothesizing potential causal connections between key cognitive factors and users intention to use the services. This study determined potential variables that may be significantly related to perceived usefulness of mobile map services through in-depth interviews with two groups: a user and an expert group. Collected data of 1109 users who took part in the internet survey were analyzed using structural equation modeling. The results indicate that satisfaction with and perceived usefulness of the mobile map services were the most significant antecedents of users attitude toward the services and behavioral intention to use them. Users attitude and flow state also affected their intention to use the services, while perceived locational accuracy, service, and display quality had notable effects on attitude. This study demonstrates the significant effects of these and other examined factors, and the findings reveal that flow played a multiple moderating roles significantly affecting various connections in the integrated research model. Both theoretical and practical implications are discussed.

What drives successful social networking services? A comparative analysis of user acceptance of Facebook and Twitter

Abstract This study identifies perceived mobility, security, connectedness, system and service quality, usefulness, attitude, and flow experience as key motivational factors for using social networking services (SNSs), and develops a theoretical model that explicates the process in which users adopt Facebook and Twitter by integrating these factors with the technology acceptance model (TAM). While results of structural equation modeling (SEM) on the collected data (N = 2,214) verified the validity and reliability of the research model, Facebook and Twitter users were found to emphasize different motivational factors when deciding to use SNSs. The implications of notable findings and directions for future studies are discussed.

Caregiving role in human–robot interaction: A study of the mediating effects of perceived benefit and social presence

Abstract This study investigates whether assigning a caregiving role to a robot or to its human interactant has psychological effects on the quality of human–robot interaction (HRI). College students interacted with a social robot in a between-subjects experiment ( N xa0=xa060) with two manipulated conditions: one where the robot played the role of an ophthalmologist (with participants serving as patients) and one where participants played the role of the ophthalmologist (with the robot serving as the patient). Results suggest that being a recipient of caregiving acts leads users to form more positive perceptions of the robot than being an ostensible caregiver to the robot. Results also indicate that perceived benefit of being in a relationship with the robot mediates the effects of the caregiving role on relationship satisfaction with—and trust towards—the robot while feelings of social presence mediate the effects on humanlike-ness and intelligence of the robot. These findings demonstrate the applicability of the Computers Are Social Actors (CASA) paradigm to the context of HRI.

Modeling the user acceptance of long-term evolution (LTE) services

With an integrated framework, this paper aims to analyze user perception and acceptance toward long-term evolution (LTE) services, focusing on factors that may influence the intention to use. We conducted a web-based survey of 1,192 users to test our research model. We employed structural equation modeling (SEM) as the analysis method. The results of the integrated model analysis indicate that system satisfaction is a core determinant of intention to use LTE services. The model also found that other factors, including perceived usefulness and system and service quality, significantly affect intention to use these services. In addition, both perceived adaptivity and processing speed significantly influence perceived usefulness and service quality, respectively. These factors also play key roles in determining users’ attitudes. This paper is of value to researchers and engineers designing and improving LTE services for use via mobile phones.

Understanding driver adoption of car navigation systems using the extended technology acceptance model

This study proposes an integrated research model for investigating driver adoption of car navigation systems. We consider the potential causal connections between core cognitive and psychological factors and driver intention to use these systems. We extracted possible factors that may significantly affect the perceived usability of car navigation systems from in-depth interviews with two groups of individuals: an expert group and a driver group. Data collected from Nu2009=u20091045 drivers via an online survey were analysed by structural equation modelling. The results showed that the service & display quality components of the systems were the most significant determinants of driver attitude and intention to use car navigation systems. Two other factors, namely attitude and perceived usefulness, also had impacts on driver intention. Moreover, both satisfaction and service & display quality were affected by perceived system reliability, while usefulness was affected by both perceived locational accuracy and satisfaction. Satisfaction also significantly affected perceived ease of use. In addition, we introduced new external variables to the technology acceptance model (TAM) and validated the causal connections proposed by the original TAM. The present study provides valuable insights into the core factors that significantly affect driver perspectives of and intention to use car navigation systems.
