In this paper we describe the results of a study which compares explicit synchronous collaborative web search with searching the web individually when users are utilizing the web for the purpose of social planning tasks, in specific travel planning. We explore both co-located and distributed collaborative search within groups of two and three participants. The distributed collaborative search i...

We discuss the physiological metrics that can be measured with electroencephalography (EEG) and functional near infrared spectroscopy (fNIRs). We address the functional and practical limitations of each device, and technical issues to be mindful of when combining the devices. We also present machine learning methods that can be used on concurrent recordings of EEG and fNIRs data. We discuss an ...

Communications between buildings and their occupants through multimodal Human Computer Interactions (HCI) can dramatically enhance the way buildings are experienced. Although building performance data is becoming more readily available, no research has been established to enable visualization of and interaction with this information in a robust way. This paper will present a method that will al...

Much of HCI concentrates on how to critique existing designs. What is more difficult is figuring out how to generate successful new designs, especially designs that are grounded in the real-world needs of the users. While it may be tempting to simply start building prototypes, it is almost always better to start by generating a collection of ideas. Ideas, even impractical or silly, help to crea...

In this position paper I argue for the merits of the experiencesampling method for HCI research and a wider scientific community and for the support of the method through publicly available, freely configurable tools. I will take a critical look at some of the relevant tools available. On that basis some recommendations for the design of ESM tools are given and a design space for ESM tools is s...

This position paper proposes to investigate the use of logs as a resource to (re)design interactive systems. By understanding what information should be captured in application logs and using mining techniques to identify the users’ behavior patterns, we hope to extract valuable information to inform HCI (re)design decisions.

This paper surveys the use of inferential statistics over the last two BCS HCI conferences and the last year (2006) of two leading HCI journals. Of the 80 papers covered, 41 used some form of inferential statistics. However, all but one had some form of problem of reporting or analysis that undermined the value or the validity of the statistical testing and hence the research findings. This pap...
