This paper presents experiences on using five different self-report methods, two adopted from literature and three self-created, for collecting information about emotional responses to mobile applications. These methods were used in nine separate field experiments done in naturalistic settings. Based on our experiments, we can argue that all of these(More)
Today’s applications such as ubiquitous systems are more and more aware of user’s habits and the context of use. The features of products and the context of use will affect the human’s experiences and preferences about the use of device. Thus, user experience in user-product interaction has been regarded as an important research topic in the mobile(More)
The effect of bovine lactoferrin (Lf) was studied in experimental Escherichia coli mastitis, using enrofloxacin as a comparator. Mastitis was induced in six clinically healthy primiparous dairy cows by infusing 1500 colony-forming units of E. coli into a single udder quarter. The challenge was repeated into a contralateral quarter of the same cows 3 weeks(More)
This paper presents a context-aware mobile application for office-type working purposes. Via the user tests we have evaluated if this kind of application can support worker's daily life. In the experiments we had real users in real working environment. Our investigation illustrates that workers could utilize context-aware features to ease up their working(More)
Ambient Intelligence or ubiquitous computing is the technology vision of the future. Ambient Intelligence will provide applications and services to users anywhere and anytime. To ensure acceptability and pleasurability, Ambient Intelligence systems should also be socially intelligent. This requires research and design sensitive to the user’s emotions. 3E is(More)
One of the essentials for the breakthrough of ubiquitous computing, a.k.a. computers everywhere, is to develop methods that reduce the demand and relieve the effort needed for conscious control by users. Solutions that incorporate sensor-based adaptation have been offered, especially in the field of mobile applications. Whether these methods succeed or not(More)
In the future, ubiquitous applications, services and environments will need adaptivity and context awareness in order to adapt to their users' requirements and needs. Before these kinds of applications can be developed, we need to know when adaptivity is at an adequate level. This article introduces a framework (dimensions and degrees) for evaluating(More)
