Techno-Trust and Rational Trust in Technology – A Conceptual Investigation
Part 2: Methodological; International audience; Trust is essential when using technology. If people do not trust new technology, they do not accept it. If people do not accept new technologies such as autonomous ships, their development is hampered in the absence of financial support. The importance of trust brings into question the essential conceptual components of phenomena that contribute to trust. This knowledge is required for the basis of investigating trust in technology. Especially, it is important to understand why humans trust. The reasons can be intuitive but they can also be supported by rational arguments. The latter type of trust can be called rational trust. A beneficial way…
Ubiquitous Co-Driver System and Its Effects on the Situation Awareness of the Driver
The aim of this paper is to explore the effects of ubiquitous computing in cars on the situation awareness and expectations of the driver. In a driving simulation environment with participants using a co-driver system, we investigated how people took and recovered from misinformation provided by the system. The system presented safety-critical information about the upcoming curves on the road, but in the experiment part of the messages contained false information. The effects of this information on participants’ behavior were investigated. On the grounds of the experiment, we discuss two approaches for investigating drivers’ situational awareness, which are based on either mental workload o…
Utilizing Experience Goals in Design of Industrial Systems
The core idea of experience-driven design is to define the intended experience before functionality and technology. This is a radical idea for companies that have built their competences around specific technologies. Although many technology companies are willing to shift their focus towards experience-driven design, reports on real-life cases about the utilization of this design approach are rare. As part of an industry-led research program, we introduced experience-driven design to metal industry companies with experience goals as the key technique. Four design cases in three companies showed that the goals are useful in keeping the focus on user experience, but several challenges are sti…
Radical innovation by theoretical abstraction - a challenge for the user-centred designer
AbstractIt is generally accepted that scientific disciplines such as psychology, sociology, and anthropology contribute beneficially to design by providing understanding of users’ needs, experiences, and desires. Arguably, however, these disciplines have more to contribute, because they include theories and models that can be applied as design frames and principles. More specifically, goal-setting, visualization, thematization, and conceptual reconfiguration are general mechanisms through which theories translate into design contributions. Actualizing radical design solutions via these mechanisms is discussed: theories provide appropriate means of abstraction, which allows ‘distance’ from u…
Defining user experience goals to guide the design of industrial systems
The key prerequisite for experience-driven design is to define what experience to design for. User experience (UX) goals concretise the intended experience. Based on our own case studies from industrial environments and a literature study, we propose five different approaches to acquiring insight and inspiration for UX goal setting: Brand, Theory, Empathy, Technology, and Vision. Each approach brings in a different viewpoint, thus supporting the multidisciplinary character of UX. The Brand approach ensures that the UX goals are in line with the company's brand promise. The Theory approach utilises the available scientific knowledge of human behaviour. The Empathy approach focuses on knowing…
Context-sensitive distraction warnings : effects on drivers' visual behavior and acceptance
In this study, we investigated the effects of context-sensitive distraction warnings on drivers' in-car glance behaviors and acceptance. The studied prototype warning application functions on a smart phone. The novelty of the application is its proactive and context-sensitive approach to the adjustment of warning thresholds according to the estimated visual demands of the driving situation ahead. In our study, novice and experienced drivers conducted in-car tasks with a smart phone on a test track with and without the warnings. The application gave a warning if the driver's gaze was recognized to remain on the smart phone over a situation-specific threshold time, or if the driver was approa…
User experience targets as design drivers:A case study on the development of a remote crane operator station
In recent years, the notion of user experience, or UX, as an essential aspect to be addressed in the design and development of technologies has been increasingly discussed. In this paper, we present a case study in which we have used UX targets as the main design drivers and focus areas in developing a new remote operator station user interface for container cranes. UX targets describe the experiential qualities to which the product design should aim at. However, taking UX targets into consideration during product design is challenging, because only little is known about how they would be best operationalized to serve the different phases of the design process. Through our case study, we de…
Evaluation of user experience goal fulfillment
In this paper, the results of a user experience (UX) goal evaluation study are reported. The study was carried out as a part of a research and development project of a novel remote operator station (ROS) for container gantry crane operation in port yards. The objectives of the study were both to compare the UXs of two different user interface concepts and to give feedback on how well the UX goals experience of safe operation, sense of control, and feeling of presence are fulfilled with the developed ROS prototype. According to the results, the experience of safe operation and feeling of presence were not supported with the current version of the system. However, there was much better suppor…
Designing and Evaluating Ubicomp Characteristics of Intelligent In-Car Systems
In this paper, we present a preliminary taxonomy for designing and evaluating intelligent systems from the viewpoint of ubiquitous computing (ubicomp). As an example of intelligent systems, we examine a few novel in-car systems, which are already commercially available. We also discuss some ergonomics issues related to the design of in-car systems and argue that rationale for solving these issues can be found from the ideal qualities of ubicomp systems. The five characteristics we define to be ideal for genuine ubicomp systems are context-awareness, natural interaction methods, invisibility, support for everyday tasks, and interconnectivity. Based on these characteristics, we create a frame…
A preliminary framework for differentiating the paradigms of human-technology interaction research
The purpose of this paper is to clarify the differences between approaches in the research field of human-technology interaction. We are especially interested in individuating user psychology from the more traditional paradigms. Therefore, we suggest a preliminary theoretical framework of criteria for distinguishing and individuating the different interaction research paradigms. The framework consists of five dimensions in which the paradigms may vary from each other. In this paper, we also discuss how ubiquitous computing is related to some of the dimensions. In addition, we focus on defining the new elements user psychology can bring to the discussion and analysis of human-technology inte…
