How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Regulations restrict UAVs to fly only within direct view of the pilot, limiting their ability to support critical societal functions. One potential way to move beyond this limitation is by placing a 360-degree camera on the vehicle and using its feed to provide operators with a view that is the equivalent to being on the vehicle. This necessitates...
Phobias have historically and evolutionary been vital for humans to escape quickly or fight in dangerous situations. The anxieties that phobias evoke have made people live longer. Evolutionarily, anxiety has been good, but fear and anxiety come in unjustified situations for the civilized population in the 21st century. Some people have an extra sen...
Exposure to airborne particles causes detrimental health effects, hence their assessment in indoor environments, where people spend most of the time, is important. The influence of energy renovation and occupants' activities on airborne particle concentrations was assessed in seven occupied Swedish residences. Ultrafine particle (UFP, <100 nm) numb...
Today, just as in the early days of flying, much emphasis is put on the pilot student’s flight training before flying a real commercial aircraft. In the early stages of a pilot student’s education, they must, for example, learn different operating procedures known as flow patterns using very basic tools, such as exhaustive manuals and a so-called p...
In the digitalized era, we do less and less physical work, which in turn leads to less physical activities. Many different wearables and applications try to motivate us to exercise more but people stop using them after a couple of months. One of the reasons people stop using them is because they serve as a post-activity viewing and not as a motivat...
More and more things are getting connected to the internet, including lights, speakers, and refrigerators. These connected things are an example of what a smart home system that is part of the Internet of Things (IoT) can incorporate. IoT enables advanced services by interconnecting physical and virtual things. But, building interactive prototypes...
Lately, different wearable form factors have reached the consumer domain. Wearables enable at-a-glance access to information and can continually sense the surrounding environment. Internet of Things (IoT) researchers have focused on the main enabling factors: the integration of several technologies and communication solutions. Less effort has been...
Head-mounted displays and other wearable devices open up for innovative types of interaction for wearable augmented reality (AR). However, to design and evaluate these new types of AR user interfaces, it is essential to quickly simulate undeveloped components of the system and collect feedback from potential users early in the design process. One w...
Recently, we have seen an intensified development of head mounted displays (HMD). Some observers believe that the HMD form factor facilitates Augmented Reality (AR) technology, a technology that mixes virtual content with the users' view of the world around them. One of many interesting use cases that illustrate this is a smart home in which a user...
There are all sorts of consumer electronics in a home environment. Using "apps" to interact with each device is neither feasible nor practical in an ubicomp future. Prototyping and evaluating interaction concepts for this future is a challenge. This paper proposes four concepts for device discovery and device interaction implemented in a virtual en...
In this paper, a personal assistant and navigator system for visually impaired people will be described. The showcase presented in-tends to demonstrate how partially sighted people could be aided by the technology in performing an ordinary activity, like going to a mall and moving inside it to find a specific product. We propose an Android ap-plica...
Wizard of Oz methodology is useful when conducting user studies of a system that is in early development. It is essential to be able to simulate part of the system and to collect feedback from potential users. Using a human to act as the system is one way to do this.
The Wizard of Oz tool presented here is called WozARd and it aims at offering a se...
