This input device acts as a normal touchpad, but also senses pressure for additional control. Tactile feedback is provided to indicate the state of the user interface to the user. By sensing the finger contact area, pressure can be treated in two ways. This combination enables various user interactions, including multiple hardware button emulation, map scrolling with continuous scale change, and list scrolling with pressure-based speed control.","PeriodicalId":201154,"journal":{"name":"CHI '06 Extended Abstracts on Human Factors in Computing Systems","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115361271","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}

Existing pathway selection interfaces are frustratingly difficult to use, since they require the 3D placement of regions-of-interest within the brain data using only a mouse and keyboard. The proposed system addresses these usability problems by providing an interface that is potentially more intuitive and powerful: converting 2D mouse gestures into 3D path selections. The contributions of this work are twofold: 1) we introduce a participatory design process in which users invent and test their own gestural selection interfaces using a Wizard of Oz prototype, and 2) this process has helped to yield the design of an interface for 3D pathway selection, a problem that is known to be difficult. Aspects of both the design process and the interface may generalize to other interface design problems.","PeriodicalId":201154,"journal":{"name":"CHI '06 Extended Abstracts on Human Factors in Computing Systems","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126757243","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}

HCI has much to offer here in helping apply information technologies in effective, usable ways. But a fundamental issue in solving these persistent problems is ensuring that steady progress is made, and HCI can play a role here too, by characterizing the task, helping define the metrics for progress, providing the interfaces on which progress hinges, and assessing the likely effect of design choices. These cases can benefit from taking an engineering approach and from using HCI as a part of that activity. Speakers will present cases that involve variations on this theme. Their presentations will provide a basis for a lively discussion of HCI's potential to make an impact on social problems in the future and the methods effective in realizing this potential.","PeriodicalId":201154,"journal":{"name":"CHI '06 Extended Abstracts on Human Factors in Computing Systems","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115036156","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}

This paper argues that a new perspective on the concept \"community\" can shed light on the subject. Ideas from cognitive science, particularly category theory, can help. I suggest that community can be viewed as a prototype-based category. Prototype-based categories are defined not by simple rules of inclusion and exclusion, but instead by their prototypical members--a robin is a better example of a bird than an emu or a penguin. Items in a category are better or worse examples of the category depending on their degree of similarity to the prototypical members. I will argue that these theoretical insights can help resolve debates about the nature of community, and also can help guide designers of computer-mediated communication (CMC) systems.","PeriodicalId":201154,"journal":{"name":"CHI '06 Extended Abstracts on Human Factors in Computing Systems","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114415292","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}
