{"title":"The hunt for usability: tracking eye movements","authors":"K. Karn, Steve Ellis, Cornell Juliano","doi":"10.1145/632716.632823","DOIUrl":"https://doi.org/10.1145/632716.632823","url":null,"abstract":"Usability testing methods have not changed significantly since the origins of the practice. Usability studies typically address human performance at a readily observable task-level, including measures like time to complete a task, percentage of participants succeeding, type and number of errors, and subjective ratings of ease of use [3]. Certain types of questions are difficult to answer efficiently with these techniques. Imagine, for example, that we observe users spending longer than expected looking at a particular dialog of a software application or web page without making the appropriate selection to complete the task. Participants often have difficulty reporting their behavior and the experimenter is clueless about what went wrong. Is it because the user is overlooking the control? Is the user distracted by another element in the interface -- perhaps an animated graphic? Is the user seeing the control, but failing to comprehend its meaning? Different answers to these questions would clearly lead to different recommendations. If overlooking the control is a problem, increasing its salience is appropriate. If confusion of the control's function is a problem, changing the graphic or text label may be appropriate. If distraction is a problem, decreasing the salience of other stimuli may help. Without answers to these questions, design recommendations have to be implemented by trial and error. Recording the fixation pattern of the participant's eyes can offer additional information to help answer these questions. While this concept is not new, it has been confined primarily to military aircraft cockpit issues [2,4]. Only recently has eye tracking technology advanced to make it practical in the broader usability community. Usability studies of human-computer systems that have included eye tracking, e.g., [1] are beginning to show benefits of these techniques. However, important challenges remain.","PeriodicalId":263696,"journal":{"name":"CHI '99 Extended Abstracts on Human Factors in Computing Systems","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121227947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, we have seen an explosion of legislative and treaty proposals. Legislation was recently passed that attempts to protect intellectual property on the Net by outlawing some devices and technologies that can be used to \"circumvent\" measures restricting access. This legislation has several bad features, among them the unintended side effect of making some legitimate computer security research illegal. It could even criminalize some techniques that are required to correct Y2K problems. Both the legislation that is passed and the manner in which technology is implemented will have a major impact on the rights and responsibilities of creators and users of intellectual property. How will copyright he impacted? What will happen to user rights of fair use and first sale? Are we moving from copyright protection of books and magazines on the net to contract law, and if so, what are the potential repercussions? Will free libraries become a thing of the past, to be replaced by pay-per-view?The manner in which these questions are resolved will have a significant impact on our society.","PeriodicalId":263696,"journal":{"name":"CHI '99 Extended Abstracts on Human Factors in Computing Systems","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121391439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stolze, Jürgen Koenemann","doi":"10.1145/632716.632926","DOIUrl":"https://doi.org/10.1145/632716.632926","url":null,"abstract":"The number of Internet users and goods sold over the Internet is increasing rapidly. To keep this momentum user interfaces for electronic shops have to adapt to and anticipate the changing needs of buyers and merchants on the Internet. A CHI98 workshop on future interfaces for e-commerce [1] confirmed that electronic product catalogs are a a rapidly evolving area where advanced HCI techniques can play an important role in the creation of successful product catalogs.Only recently these catalogs have started to evolve from a static set of inter-linked web-pages into dynamic interfaces that better exploit the possibilities of the computational and networked medium. There are a number of driving forces for this development:• Increased competition between catalog operators makes it important to design catalogs in such a way that they attract customers, keep customers exploring, and make customers return.• Marketing new types of products requires new types of interfaces. For example selling complex products electronically will require additional support for buyers to make them confident in their choice.• The increased number of products, product options, product reviews, and supplier evaluations create the challenge of organizing this information in a way that is useful for the needs of individual buyers.• With the increased number of Internet users, new classes of buyers with very different needs and expectations become apparent. For example, a catalog that wants to attract shoppers that mainly come for entertainment will be different from a catalog that wants to attract bargain hunters. Some of these buyers might also be interested in new ways of buying like auctions and request-for-proposals, that were traditionally only available for professionals.A number of HCI techniques have been applied to electronic product catalogs. Among them direct manipulation, information visualization, personalization, user modeling, and anthropomorphic interface agents.The goal of this SIG is to deepen the understanding of the challenges that have to be approached by electronic product catalogs, collect information about prototypical systems, and to share experiences gained with applying HCI techniques to improve electronic product catalogs.","PeriodicalId":263696,"journal":{"name":"CHI '99 Extended Abstracts on Human Factors in Computing Systems","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114626573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have recently completed a prototype agent of this kind for helping people with their email, based on our studies of people working with human assistants and Wizard-of-Oz studies. The prototype was constructed using application-independent software for modeling collaborative discourse (Collagen, see [4]) jointly developed by Lotus and Mitsubishi Electric and speech understanding technology from IBM Research. Users perform typical email tasks via a flexible combination of spoken language conversation with the agent and graphical interface actions (which are observed by the agent). The agent maintains a model of the user's goals and activities, and can act on its own initiative to assist the user. Having a high-level model of actions and goals allows speech to be used in a more natural, conversational, and effective manner than otherwise possible.","PeriodicalId":263696,"journal":{"name":"CHI '99 Extended Abstracts on Human Factors in Computing Systems","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125701542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our experimental SIT (Sound-Image-Text) Book is a personal interactive reading experience that combines the look and feel of a real book -- a beautiful cover, paper pages and printed images and text -- with the rich, evocative quality of a movie soundtrack. The soundtrack is multi-track and includes music and sound effects. The SIT Book uses electric field sensors located in the book binding to sense the reader's casual book handling and fingering of the page; these sensors control the ambient audio. The particular point of the SIT Book is to explore the use of background sound to provide a sense of place, and to add affectto the experience of reading a book without interrupting the flow of the story.","PeriodicalId":263696,"journal":{"name":"CHI '99 Extended Abstracts on Human Factors in Computing Systems","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121850474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
