We are experiencing a trend of personal fabrication that allows non-experts to produce highly individualized objects. Beyond 3D printing, this maker movement also approaches larger-scale production machines such as computer numerically controlled (CNC) milling machines that are available in local fabrication laboratories (FabLabs). While the user interfaces and interaction techniques of small-scale 3D printers for household use adapted to the new requirements of non-experts in the last years, such an overhaul of the interfaces for larger machinery is still missing. In this work, we explore the use of augmented reality methods to support novice users in the operation of CNC milling machines. As a first step towards better support for users, we provide a camera-supported graphical and easy-to-use interface for the measurement of raw workpieces inside the machine. In this paper, we contribute our concept CaMea alongside its' prototype implementation. We further report on the findings of a first early user study.

The proliferation of Ambient Intelligence (AmI) devices and services and their integration in smart environments creates the need for a simple yet effective way of controlling and communicating with them. Towards that direction, the application of the Trigger -- Action model has attracted a lot of research with many systems and applications having been developed following that approach. This work introduces ParlAmI, a multimodal conversational interface aiming to give its users the ability to determine the behavior of AmI environments, by creating rules using natural language as well as a GUI. The paper describes ParlAmI, its requirements and functionality, and presents the findings of a user-based evaluation which was conducted.

Workers' health and safety is a major concern for the energy industry. Emerging and future technologies have the potential to deeply improve this field, and to make the workplace safer and healthier, especially if applied in concert. However, this transformation is difficult to envision by energy companies, which are tied to well-established rules, processes and solutions. This paper presents Augmented health and safety: Future Vision, a project we performed in collaboration with a worldwide energy company, to envision how emerging technologies may transform health and safety practices in the energy industry in the near future. The project aims at enabling dialogue and foster change by encouraging the development and adoption of solutions based on new technologies. By a design fiction approach, we designed and prototyped an ecosystem of physical and digital solutions for health and safety problems aimed at presenting future scenarios and triggering discussion about how to improve workplaces. Design fiction turned out to be an effective tool for enabling dialogue and inspiring change within companies.

A key issue in studying the performance of wireless sensor networks is the study of load and, depending on the case, different definitions can be found in the literature. These definitions may vary significantly and they may not allow for further investigation of particular aspects of the network's behavior, thus impending the researcher's work. The purpose of this paper is to lift any ambiguities with respect to widely used load definitions, analyze their properties and provide for a new perspective to study wireless sensor networks' performance, particularly for the case of uniform random node deployment. First, definitions regarding the node load, the average area load and the average point load, the most widely used cases considered in the literature, are presented. Subsequently, the relation among these definitions is analytically investigated, resulting in an analytical expression between the average area load and the average load of the points within this area. As it is concluded, average load can be seen as a property of every single point, even if that point is not occupied by a sensor, which introduces a different way to tackle average load problems in wireless sensor network environments.

The interest in virtual and augmented reality increased rapidly in the last years. Recently, haptic interaction and its applications get into focus. In this paper, we suggest the exploration of virtual objects using off-the-shelf VR game controllers. These are held like a pen with both hands and were used to palpate and identify the virtual object. Our study largely coincides with comparable previous work and shows that a ready-to-use VR system can be basically used for haptic exploration. The results indicate that virtual objects are more effectively recognized with closed eyes than with open eyes. In both cases, objects with a bigger morphological difference were identified the most frequently. The limitations due to quality and quantity of tactile feedback should be tackled in future studies that utilize currently developed wearable haptic devices and haptic rendering involving all fingers or even both hands. Thus, objects could be identifiable more intuitively and haptic feedback devices for interacting with virtual objects will be further disseminated.

As the amount of readily available reading material increases, the ability to read selectively, or to skim-read, is becoming an important skill. In this paper, we report a comparative study of existing skim-reading strategies in sighted and visually impaired individuals. Using a think-aloud approach, we identified key features of visual documents that allow sighted users to adopt a highly flexible and goal-oriented approach to skim-reading. These features are mostly lost when documents are accessed in auditory form, as is commonly the case for visually impaired individuals. As a result, this group has to fall back on either less efficient or cognitively more demanding exploration strategies. From our results, we propose a list of six design implications to guide the development of future technologies assisting non-visual skimming.

Wearable technology has great potential in improving the work routines of medical professionals such as nurses and orderlies in the healthcare domain. Although wearable technology such as smartwatches can have a positive impact on the life of both patients and medical professionals, its usage is often not possible due to strict hygiene regulations. In this paper, we investigate the design space for a wearable device to support medical professionals in a hospital context that meets the requirements of the 'Bare Below the Elbows' hygiene policy. We conducted two workshops with eleven medical professionals to elicit requirements and to co-design such a wearable device. Specifically, we aimed to answer questions related to the form factor, mounting options as well as must-have functionalities and features.

Nowadays, the risk of falling in older adults is a major concern due to the severe consequences it brings to socio-economic and public health systems. Some pathologies cause mobility problems in the aged population, leading them to fall and, thus, reduce their autonomy. Other implications of ageing involve having different gait patterns and walking speed. In this paper, a non-invasive framework is proposed to study gait in elder people using data collected by a smart rollator, the i-Walker. The analysis presented in this article uses a feature extraction method and a spectral embedding to represent the information and Bayesian clustering for the knowledge discovery. The algorithm considers raw data from the i-Walker sensors along with the calculated walking speed of each individual, which has been already used in clinical studies to assess physical and cognitive status of older adults. The results obtained demonstrate that the proposed analysis has the potential to separate in clusters the people of the two groups of interest: young people and geriatric.
