User Acceptance

ABSTRACT Academic Marketing is on the rise in Germany. So is Social Media Marketing. In this paper we present a concept for academic marketing based on a social media marketing strategy developed and implemented at the Environmental Campus Birkenfeld, a site of Trier University of Applied Sciences. We discuss the development and implementation of this strategy starting from an evaluation of the use and needs of social media of students, professors and other university staff. This survey provides the basis for the requirements analysis for a platform for internal and external communication, whose structure is presented here. We outline some considerations about launching such a platform and we report some very first results in terms of user acceptance and feedback.

We present the design, implementation, deployment and evaluation of a novel urban computing infrastructure called UBI-hotspot. It is effectively a large interactive public display embedded with other computing resources. We have deployed a network of UBI-hotspots around downtown Oulu, Finland, to establish a public laboratory for conducting experimental ubiquitous computing research in authentic urban setting with diverse real users and with sufficient scale and time span. We focus on the first version of the UBI-hotspot which offers a wide range of services via different interaction modalities. We analyze the usage and user acceptance of the UBI-hotspots from qualitative and quantitative data collected over a period of eight months. Our first observations show that this type of infrastructure may be a useful addition to the urban space.

Multimedia Messaging Services (MMS) is a new medium that enriches people's personal communication with their business partners, friends, or family. Following the success of Short Message Services, MMS has the potential to be the next mobile commerce “killer application” which is useful and popular among consumers; however, little is known about why people intend to accept and use it. Building upon the motivational theory and media richness theory, the research model captures both extrinsic (e.g., perceived usefulness and perceived ease of use) and intrinsic (e.g., perceived enjoyment) motivators as well as perceived media richness to explain user intention to use MMS. An online survey was conducted and 207 completed questionnaires were collected. By integrating the motivation and the media richness perspectives, the research model explains 65% of the variance. In addition, the results present strong support to the existing theoretical links as well as to those newly hypothesized in this study. Implications from the current investigation for research and practice are provided.

User studies need to be perform on the new technology such as Mixed reality
(MR) before it reach maturity. In this paper we would like to reveal the study that has been
done to determine users' perception and acceptance on the mixed reality prototype, named
Mixed Reality Regenerative Concept (MRRC). The aim of MRRC is to increase users
understanding on regenerative concept and tissue engineering.

This research investigates the applicability of Davis' technology acceptance model to user acceptance of a knowledge management information system. It addresses two important questions: "Does the technology acceptance model explain user acceptance and usage of an information system implemented to support knowledge management objectives?" ''Can previous technology acceptance model user acceptance research serve as a basis for investigation of user acceptance of knowledge management information technology systems?" This study provides preliminary evidence that previous information technology acceptance research based on the technology acceptance model, may serve as a foundation for research of knowledge management system user acceptance. Relationships among primary TAM constructs are in substantive agreement with those characteristic of previous TAM research. Significant positive relationships between perceived usefulness, ease of use, and system usage were consistent with previous TAM research. The observed mediating role of perceived usefulness in the relationship between ease of use and usage was also in consonance with earlier findings. The findings are significant because they suggest that the considerable body of previous TAM related information technology research may be usefully applied to the knowledge management domain, and promote further investigation of factors affecting the user acceptance and usage of knowledge management information systems.

This paper presents the design and implementation of a distributed virtual reality (VR) platform that was developed to support the training of multiple users who must perform complex tasks in which situation assessment and critical thinking are the primary components of success. The system is fully immersive and multimodal, and users are represented as tracked, full-body figures. The system supports the manipulation of virtual objects, allowing users to act upon the environment in a natural manner. The underlying intelligent simulation component creates an interactive, responsive world in which the consequences of such actions are presented within a realistic, time-critical scenario. The focus of this work has been on the training of medical emergency-response personnel. BioSimMER, an application of the system to training first responders to an act of bio-terrorism, has been implemented and is presented throughout the paper as a concrete example of how the underlying platform archit...

Building on recent unique, yet potentially complementary, approaches to understanding the formation of user perceptions about technology (Venkatesh, 1999; Venkatesh & Speier, 1999), the present work reanalyzes the data from both studies to develop an integrated model of technology acceptance. The integrated model specifically examines the influence of pre-training and training environment interventions (termed user acceptance enablers) to understand how user perceptions are formed prior to system implementation. The model is then further extended and tested using longitudinal data in a field setting. The results indicate that the integrated model emerged as a better predictor of user behavior when compared to the existing models.

Errors in requirements specifications have been identified as a major contributor to costly software project failures. It would be highly beneficial if information systems developers could verify requirements by predicting workplace acceptance of a new system based on user evaluations of its specifications measured during the earliest stages of the development project, ideally before building a working prototype. However, conventional wisdom among system developers asserts that prospective users must have direct hands-on experience with at least a working prototype of a new system before they can provide assessments that accurately reflect future usage behavior after workplace implementation. The present research demonstrates that this assumption is only partially true. Specifically, it is true that stable and predictive assessments of a system's perceived ease of use should be based on direct behavioral experience using the system. However, stable and behaviorally predictive measures of perceived usefulness can be captured from target users who have received information about a system's functionality, but have not had direct hands-on usage experience. This distinction is key because, compared to ease of use, usefulness is generally much more strongly linked to future usage intentions and behaviors in the workplace. Two longitudinal field experiments show that preprototype usefulness measures can closely approximate hands-on based usefulness measures, and are significantly predictive of usage intentions and behavior up to six months after workplace implementation. The present findings open the door toward research on how user acceptance testing may be done much earlier in the system development process than has traditionally been the case. Such preprototype user acceptance tests have greater informational value than their postprototype counterparts because they are captured when only a relatively small proportion of project costs have been incurred and there is greater flexibility to modify a new system's design attributes. Implications are discussed for future research to confirm the robustness of the present findings and to better understand the practical potential and limitations of preprototype user acceptance testing.

Most Brain–Computer Interface (BCI) research aims at helping people who are severely paralyzed to regain control over their environment and to communicate with their social environment. There has been a tremendous increase in BCI research the last years, which might lead to the belief that we are close to a commercially available BCI applications to patients. However, studies with users from the future target group (those who are indeed paralyzed) are still outnumbered by studies on technical aspects of BCI applications and studies with healthy young participants. This might explain why the number of patients who use a BCI in daily life, without experts from a BCI group being present, can be counted on one hand.

—Personal Health Records (PHRs) can be considered as one of the most important health technologies. PHRs enroll the patients directly to their health decision making through giving them the authority to control and share their health information. Testing the user acceptance toward new technology is a vital process. Over the previous decades many models have been used and the latest one was UTAUT2. UTAUT2 have been widely used in e-business and gaming user acceptance researches, whereas, it has been rarely used in health field. This study proposes a combination of UTAUT2 and PMT in order to investigate the user acceptance of PHRs. Relevant factors may be added at the literature review stage. The final model will be used as a framework to investigate the user acceptance of PHRs in Malaysia.
