Seeing where people look while using your Web site, Web application, or software product sounds like an opportunity to get amazing insights into their user experience. But eyetracking is expensive and requires extra effort and specialized knowledge. The heat maps and other visualizations certainly look impressive, but what can you really learn from them? After using eyetracking for the first time, many find that it is not easy to know how to analyze the visualizations and make conclusions from them. Does eyetracking really provide any additional insights you would not have discovered anyway through traditional usability testing? Does the value of eyetracking outweigh its limitations? This article will discuss and answer these questions. http://tc.eserver.org/35446.html http://tc.eserver.org/35446.html Eye tracking has been investigated and 'toyed with' for many years by researchers and commercial usability professionals. Many new techniques and therefore interesting and powerful results are now available. http://tc.eserver.org/35447.html http://tc.eserver.org/35447.html Incorporation of eye position recording into product usability evaluation can provide insights into human-computer interaction that are not available from traditional usability testing methods. We present here some thoughts on this topic which arose primarily from a CHI 99 workshop. This workshop brought together human-computer interaction designers, eye movement researchers and usability testing specialists for a discussion about how to extract information about product usability from users’ eye movements. http://tc.eserver.org/31196.html http://tc.eserver.org/31196.html This article discusses users' visual scan paths of web pages containing text and/or pictures while conducting browsing and searching tasks. User performance on three usability tasks on an e-commerce website is described. Results show that users follow a fairly uniform scan path when browsing through pictures, and a more random path while specifically searching through them. Additionally, users appeared to follow Nielsen's 'F' pattern (2006) while both browsing and searching through text-based pages. http://tc.eserver.org/29678.html http://tc.eserver.org/29678.html Eye-tracking systems can enrich a Website usability study by providing an additional method for observing users' behavior. While eye-trackers can provide valuable data, the pros and cons of adding eye-tracking to a usability study need to be considered before designing the study's protocol. This paper discusses the kinds of usability questions that benefit from eye-tracking data and considerations for designing and running the study. Our findings are based on work done in the Laboratory for Usability Testing and Evaluation (LUTE) at the University of Washington, which is equipped with the Eye-gaze Response Computer Aid (ERICA) system controlled by the Gaze Tracker software, both of which were developed by Eye Response Technologies, Inc. http://tc.eserver.org/29563.html http://tc.eserver.org/29563.html Eye tracking tools have recently attracted attention from usability professionals. Eye tracking offers usability researchers a new way to identify very fine-grained behaviors that indicate usability problems. This paper is a comparison of different types of eye tracking tools and their potential usefulness in usability testing. Specifically, the paper examines the cost of the systems, system types, sampling rate, and some system limitations. The paper aims to provide a basic introduction to technical communicators who are considering adding an eye- tracking system to their toolkit. http://tc.eserver.org/28894.html http://tc.eserver.org/28894.html The bottom line is how to ensure the customer that eye tracking provides additional value for their money. If we do numerical analysis in addition to video analysis, the need for extra time is remarkable and the analysis will become more expensive. To reduce analysis time we need automated special software and therefore we are currently developing scan path visualization software in which we include a new fixation recognition algorithm. http://tc.eserver.org/27526.html http://tc.eserver.org/27526.html This article discusses how eye-tracking can be used to supplement traditional usability test measures. User performance on two usability tasks with three e-commerce websites is described. Results show that eye-tracking data can be used to better understand how users initiate a search for a targeted link or web object. Frequency, duration and order of visual attention to Areas of Interest (AOIs) in particular are informative as supplemental information to standard usability testing in understanding user expectations and making design recommendations. http://tc.eserver.org/26871.html http://tc.eserver.org/26871.html This article discusses how eye-tracking can be used to supplement traditional usability test measures.
