Employee acceptability of wearable mental workload monitoring in industry 4.0 : a pilot study on motivational and contextual framing

As Industry 4.0 will greatly challenge employee mental workload (MWL), research on objective wearable MWL-monitoring is in high demand. However, numerous research lines validating such technology might become redundant when employees eventually object to its implementation. In a pilot study, we manipulated two ways in which employees might perceive MWL-monitoring initiatives. We found that framing the technology in terms of serving intrinsic goals (e.g., improving health) together with an autonomy-supportive context (e.g., allowing discussion) yields higher user acceptability when compared to framing in terms of extrinsic goals (e.g., increasing productivity) together with a controlling context (e.g., mandating use). User acceptability still panned out neutral in case of the former, however - feeding into our own and suggested future work

Tactons: structured tactile messages for non-visual information display

Tactile displays are now becoming available in a form that can be easily used in a user interface. This paper describes a new form of tactile output. Tactons, or tactile icons, are structured, abstract messages that can be used to communicate messages non-visually. A range of different parameters can be used for Tacton construction including: frequency, amplitude and duration of a tactile pulse, plus other parameters such as rhythm and location. Tactons have the potential to improve interaction in a range of different areas, particularly where the visual display is overloaded, limited in size or not available, such as interfaces for blind people or in mobile and wearable devices. This paper describes Tactons, the parameters used to construct them and some possible ways to design them. Examples of where Tactons might prove useful in user interfaces are given

A pathway to independence : wayfinding systems which adapt to a visually impaired person's context

Despite an increased amount of technologies and systems designed to address the navigational requirements of the visually impaired community of approximately 7.4 million in Europe, current research has failed to sufficiently address the human issues associated to their design and use. As more types of sensing technologies are developed to facilitate visually impaired travellers for different navigational purposes (local vs. distant and indoor vs. outdoor), an effective process of synchronisation is required. This synchronisation is represented through context-aware computing, which allows contextual information to not just be sensed (like most current wayfinding systems), but also adapted, discovered and augmented. In this paper, three user studies concerning the suitability of different types of navigational information for visually impaired and sighted people are described. For such systems to be effective, human cognitive maps, models and intentions need to be the focus of further research, in order to provide information that is tailored to a user's task, situation or environment. Methodologies aimed at establishing these issues need to be demonstrated through a multidisciplinary framework

Adding generic contextual capabilities to wearable computers

Context-awareness has an increasingly important role to play in the development of wearable computing systems. In order to better define this role we have identified four generic contextual capabilities: sensing, adaptation, resource discovery, and augmentation. A prototype application has been constructed to explore how some of these capabilities could be deployed in a wearable system designed to aid an ecologist's observations of giraffe in a Kenyan game reserve. However, despite the benefits of context-awareness demonstrated in this prototype, widespread innovation of these capabilities is currently stifled by the difficulty in obtaining the contextual data. To remedy this situation the Contextual Information Service (CIS) is introduced. Installed on the user's wearable computer, the CIS provides a common point of access for clients to obtain, manipulate and model contextual information independently of the underlying plethora of data formats and sensor interface mechanisms

Ubiquitous computing: Anytime, anyplace, anywhere?

Computers are ubiquitous, in terms that they are everywhere, but does this mean the same as ubiquitous computing? Views are divided. The convergent device (one-does-all) view posits the computer as a tool through which anything, and indeed everything, can be done (Licklider & Taylor, 1968). The divergent device (many-do-all) view, by contrast, offers a world where microprocessors are embedded in everything and communicating with one another (Weiser, 1991). This debate is implicitly present in this issue, with examples of the convergent device in Crook & Barrowcliff's paper and in Gay et al's paper, and examples of the divergent devices in Thomas & Gellersen's paper and Baber's paper. I suspect both streams of technology are likely to co-exist

New Technologies and the Impact on Personality Rights in Brazil

As technology continues to evolve at an exponentially increasing pace, it transforms our lives and societies, thus shaping our perceptions of reality with high speed and impacting the relationship between the individual and the society, including businesses and, as a result, the legal system. The young area of law is trying to explore the effects of new technologies in our relationships with it, as well as identify the best use of new technologies to reduce the gap among new technology, new societal behaviors and various legal systems. The purpose of this paper is to examine the current uses of wearable technologies in Brazil and the legal issues emerging from the various uses of these technologies and their impact on personality rights. So, to what extent do the Brazilian users of emerging technologies appreciate the terms and conditions agreed by themselves and their impact on personality rights? The authors used empirical quantitative data from a cross-section of Brazilian users to explore the level of awareness in regards to the terms and conditions associated with the use of emerging technologies and the impact on their personality rights. The authors found that the large majority of these users of technology are unaware of the adverse impact of the agreed terms and conditions on their personality rights. Furthermore, they are also unaware of the basics of how the technology operates and therefore are unable to enforce their rights. The research is based on data collected by using only one survey with a sample of 500 students from three universities in three Brazilian States with an age range between 18 and 40 years old. This paper extends the previous research on the impact of emerging technologies on personality rights and demonstrates with empirical data that there is a serious risk of erosion of such rights. Furthermore, this research provides a unique insight into the users of emerging technologies in the emerging Brazilian market and the impact on the Brazilian legal system

User Driven Innovation: Incorporating Disabled Lead Users in Early Phase Product Development

How can disabled non-designers play a leading role in product development? As part of early phase product ideation, designers often rely on methods (Pahl & Beitz, 1996, Chapter 4). These methods help designers develop appropriate solutions to design problems. However, ideation processes may also involve non-designers. These could be end-users, managers, domain experts or other stakeholders. A very specific form of user involvement is through lead users. Lead users can be identified as: 1) being at the leading edge of an important market trend, and experiencing needs that will later be experienced by many users in that market, and 2) anticipating relatively high benefits from obtaining a solution to their needs. This motivates them to participate. They are often a limited group of persons with specialized skills or experiences (Urban & von Hippel, 1988). In this paper discuss the involvement of disabled lead users in early product development. We will focus on generative methods used for the creation of a wearable mobility device. The device consists, in part, of a 3D, time-of-flight DepthSense camera by Softkinetic, combined with a wearable tactile display developed by Elitac, two technology manufacturers. In addition to reflecting on our approach, we also introduce relevant research themes involving disabled lead users

Affective Medicine: a review of Affective Computing efforts in Medical Informatics

Background: Affective computing (AC) is concerned with emotional interactions performed with and through computers. It is defined as “computing that relates to, arises from, or deliberately influences emotions”. AC enables investigation and understanding of the relation between human emotions and health as well as application of assistive and useful technologies in the medical domain. Objectives: 1) To review the general state of the art in AC and its applications in medicine, and 2) to establish synergies between the research communities of AC and medical informatics. Methods: Aspects related to the human affective state as a determinant of the human health are discussed, coupled with an illustration of significant AC research and related literature output. Moreover, affective communication channels are described and their range of application fields is explored through illustrative examples. Results: The presented conferences, European research projects and research publications illustrate the recent increase of interest in the AC area by the medical community. Tele-home healthcare, AmI, ubiquitous monitoring, e-learning and virtual communities with emotionally expressive characters for elderly or impaired people are few areas where the potential of AC has been realized and applications have emerged. Conclusions: A number of gaps can potentially be overcome through the synergy of AC and medical informatics. The application of AC technologies parallels the advancement of the existing state of the art and the introduction of new methods. The amount of work and projects reviewed in this paper witness an ambitious and optimistic synergetic future of the affective medicine field
