Oliveira, Flavio T. P., Aula, Anne and Russell, Daniel M. (2009): Discriminating the relevance of web search results with measures of pupil size. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 2209-2212. Available online
“The overwhelming amount of information on the web makes it critical for users to quickly and accurately evaluate the relevance of content. Here we tested whether pupil size can be used to discriminate the perceived relevance of web search results. Our findings revealed that measures of pupil size carry information that can be used to discriminate the relevance of text and image web search results, but the low signal-to-noise ratio poses challenges that need to be overcome when using this technique in naturalistic settings. Despite these challenges, our findings highlight the promise that pupillometry has as a technique that can be used to assess interest and relevance in web interaction in a non-intrusive and objective way.”

Aula, Anne and Kellar, Melanie (2009): Multilingual search strategies. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 3865-3870. Available online
“We explored the search strategies of multilingual searchers, i.e., users who use multiple languages when searching for information. We wanted to understand factors that determine the language multilingual searchers choose to search in, if they switch languages within a search task, and if they encounter challenges when searching in a non-native language. Our results indicate that availability and perceived quality of information were the primary reasons for searching in a non-native language. Language switching within a search only occurred when information could not be found with the original search language. We also observed a language-related use case where the goal was not to find information in a typical sense, but rather to check for correct phrases in the non-native language using search engines. Our research highlights several areas of future work for further understanding the multilingual search process.”

“Teenagers are often presented as comfortable users of technology. To better understand this assumption, we asked 27 teenagers to complete a survey about the previous day's media use; we then interviewed the participants about these entries. The participants actively used computers for information, communication and entertainment. Most of the comments about technology were positive, but our study also revealed problems in the teenagers' computer use. They had stories about parents and teachers restricting their use of the web and there were several instances in which the teens themselves found the web to be offensive, inappropriate and unreliable.”

“We analyzed the patterns of coordination between users' eye movements and mouse movements when scanning a web search results page, using data gathered from a study with 32 participants. We discovered 3 patterns of active mouse usage: following the eye vertically with the mouse, following the eye horizontally with the mouse, and using the mouse to mark a promising result.”

Majaranta, Päivi, MacKenzie, I. Scott, Aula, Anne and Räihä, Kari-Jouko (2006): Effects of feedback and dwell time on eye typing speed and accuracy. In Universal Access in the Information Society, 5 (2) pp. 199-208
“Eye typing provides a means of communication that is especially useful for people with disabilities. However, most related research addresses technical issues in eye typing systems, and largely ignores design issues. This paper reports experiments studying the impact of auditory and visual feedback on user performance and experience. Results show that feedback impacts typing speed, accuracy, gaze behavior, and subjective experience. Also, the feedback should be matched with the dwell time. Short dwell times require simplified feedback to support the typing rhythm, whereas long dwell times allow extra information on the eye typing process. Both short and long dwell times benefit from combined visual and auditory feedback. Six guidelines for designing feedback for gaze-based text entry are provided.”

Kaki, Mika and Aula, Anne (2005): Findex: improving search result use through automatic filtering categories. In Interacting with Computers, 17 (2) pp. 187-206
“Long result lists from web search engines can be tedious to use. We designed a text categorization algorithm and a filtering user interface to address the problem. The Findex system provides an overview of the results by presenting a list of the most frequent words and phrases as result categories next to the actual results. Selecting a category (word or phrase) filters the result list to show only the results containing it. An experiment with 20 participants was conducted to compare the category design to the de facto standard solution (Google-type ranked list interface). Results show that the users were 25% faster and 21% more accurate with our system. In particular, participants' speed of finding relevant results was 40% higher with the proposed system. Subjective ratings revealed significantly more positive attitudes towards the new system. Results indicate that the proposed design is feasible and beneficial.”

Aula, Anne (2005): User study on older adults' use of the Web and search engines. In Universal Access in the Information Society, 4 (1) pp. 67-81
“Ten older adults were interviewed about the motivational factors behind learning to use computers and the negative and positive aspects related to it. They were then given search tasks and were observed as they used search engines for finding information from the Web. All of the participants completed several search tasks during the search session. Although their performance in the search tasks was adequate, they faced several problems in the interaction. For example, text editing was difficult and understanding the structure of the Web and terminology used caused problems. Based on the observations, an elderly friendly search user interface is proposed.”

“Experienced web users have strategies for information search and re-access that are not directly supported by web browsers or search engines. We studied how prevalent these strategies are and whether even experienced users have problems with searching and re-accessing information. With this aim, we conducted a survey with 236 experienced web users. The results showed that this group has frequently used key strategies (e.g., using several browser windows in parallel) that they find important, whereas some of the strategies that have been suggested in previous studies are clearly less important for them (e.g., including URLs on a webpage). In some aspects, such as query formulation, this group resembles less experienced web users. For instance, we found that most of the respondents had misconceptions about how their search engine handles queries, as well as other problems with information search and re-access. In addition to presenting the prevalence of the strategies and rationales for their use, we present concrete designs solutions and ideas for making the key strategies also available to less experienced users.”

Hoysniemi, Johanna, Aula, Anne, Auvinen, Petra, Hannikainen, Jaana and Hamalainen, Perttu (2004): Shadow boxer: a physically interactive fitness game. In: Proceedings of the Third Nordic Conference on Human-Computer Interaction October 23-27, 2004, Tampere, Finland. pp. 389-392. Available online
“This paper presents a prototype implementation of a physically interactive fitness game called Shadow Boxer. The game is controlled by body movements and it utilizes a web camera to detect the player's movements. A user study was conducted to study the playability and the effectiveness of the game as an exercising method. The results showed that playing the game significantly increased the participants' heart rate and for most of the participants, the heart rate was at the optimal exercise level after playing the game. Thus, the game can be effectively used as an exercise method. Generally, the participants enjoyed playing the game and thought of it as a possible method for training. Additionally, the study revealed ideas for improving the game experience and the usability of the interface.”
