- Virtual Reality (VR) is used for a variety of applications ranging from entertainment to psychological medicine. VR has been demonstrated to influence higher order cognitive functions and cortical plasticity, with implications on phobia and stroke treatment. An integral part for successful VR is a high sense of presence - a feeling of 'being there' in the virtual scenario. The underlying cognitive and perceptive functions causing presence in VR scenarios are however not completely known. It is evident that the brain function is influenced by drugs, such as ethanol, potentially confounding cortical plasticity, also in VR. As ethanol is ubiquitous and forms part of daily life, understanding the effects of ethanol on presence and user experience, the attitudes and emotions about using VR applications, is important. This exploratory study aims at contributing towards an understanding of how low-dose ethanol intake influences presence, user experience and their relationship in a validated VR context. It was found that low-level ethanol consumption did influence presence and user experience, but on a minimal level. In contrast, correlations between presence and user experience were strongly influenced by low-dose ethanol. Ethanol consumption may consequently alter cognitive and perceptive functions related to the connections between presence and user experience.

"Touch me" - Workshop on tactile user experience evaluation methods
- 2014
-
Ingår i: Proceeding CHI EA '14 CHI '14 Extended Abstracts on Human Factors in Computing Systems. - New York, NY, USA : Association for Computing Machinery (ACM). - 9781450324748 ; , s. 41-44

Konferensbidrag (refereegranskat)abstract
- In this workshop we plan to explore the possibilities and challenges of physical objects and materials for evaluating the User Experience (UX) of interactive systems. These objects should face shortfalls of current UX evaluation methods and allow for a qualitative (or even quantitative), playful and holistic evaluation of UX - without interfering with the users' personal experiences during interaction. This provides a tactile enhancement to a solely visual stimulation as used in classical evaluation methods. The workshop serves as a basis for networking and community building with interested HCI researchers, designers and practitioners and should encourage further development of the field of tactile UX evaluation.

Two actors : Providers and consumers inform the design of an ambient energy saving display with persuasive strategies
- 2013

Ingår i: CEUR Workshop Proceedings. - : CEUR-WS.

Konferensbidrag (refereegranskat)abstract
- Ambient persuasive displays could be a potential way to raise awareness and lower the energy consumption in private households. There already exist a range of products in this direction. However, none of them seem to have any longterm persuasive effects. We argue that this effect could only be enabled by involving providers and potential users in the design process of an ambient persuasive display, which aims to lower energy consumption. In this paper, we present the results of five expert interviews with energy consultants and a participatory design workshop with six potential consumers. We focused on the ideal persuasive strategies as the requirement. In here, we show the commonalities and differences between these two stakeholders, demonstrating the relevance of taking both sides into account in the design to support behavior change systems.

Co-designing for NFC and ATMs: an inspirational bits approach
- 2013. - 7
-
Konferensbidrag (refereegranskat)abstract
- This paper addresses the field of mobile payment through Near Field Communication (NFC) and Automated Teller Machines (ATMs). We report how we used the Inspirational Bits method to inspire the design of novel NFC usage scenarios and application ideas for ATMs in a joint industry and academia project. We describe a set of small applications exposing different properties of NFC (henceforth, referred to as NFC-Bits) and how they informed and inspired collaborative design ideas for different use cases. The NFC-Bits reveal a broad range of NFC characteristics in a playful manner. We outline some of the developed use cases and describe features of MyPocketATM, an application stemmed from these ideas.
