Three wearable devices with different shape, color and size have been developed: tangible mascot, box-shaped notifier and PDA virtual agent. They have a common function: to assist the user in various situations in everyday life. Likert scale questionnaires have been used to analyze the users' attitudes and preferences towards the interfaces in two basic modes: passive by visual observation and active through use-case scenarios. A separate study was conducted to correlate the visual effect patterns with the notification-message context. The usability of the proposed interfaces was measured by SUS (system usability scale). The relevant factors for appropriate information notification of each wearable interface were obtained and analyzed. The mascot was shown to be a preferred interface suitable for developing a personal relation with the user, while the box-shaped interface was found to be most helpful and suitable for business use.","PeriodicalId":407425,"journal":{"name":"Eighth International Symposium on Wearable Computers","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116847296","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}

While needless interruption of the user should be avoided, there are times when the information is of such importance that it must demand the user's attention. As the user is mobile and likely interacts with the real world when these situations occur, it is important to know in what way the user can be notified without increasing her cognitive workload more than necessary. To investigate ways of presenting information without increasing the cognitive workload of the recipient, an experiment was performed testing different approaches. The experiment described in this paper is based on an existing study of interruption of people in human-computer interaction, but our focus is instead on finding out how this applies to wearable computer users engaged in real world tasks.","PeriodicalId":407425,"journal":{"name":"Eighth International Symposium on Wearable Computers","volume":"157 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116876374","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 introduce our method for this evaluation and present the results for a widely studied activity recognition task: the classification of human modes of locomotion using body-worn acceleration sensors. With this example we show that both the sampling frequency and the resolution can be significantly reduced without much impact on the recognition performance. While many of the published approaches in this domain rely on higher sampling frequencies and signal resolutions, we show that good recognition performance can already be achieved with 20 Hz and 2 bit resolution.","PeriodicalId":407425,"journal":{"name":"Eighth International Symposium on Wearable Computers","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131879815","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}

By giving the user tactile feedback about the length of a stroke during input, we decrease the dependence of the GUI on the visual display. By concatenating separate strokes into multistrokes, complex commands may be entered, which may encode commands, data content, or both simultaneously. To demonstrate their power, we show how multistrokes can be used to traverse a menu hierarchy quickly. In addition, we show how inter-landmark segments of the sensor may be used for continuous and discrete parameter entry, resulting in a multifunctional interaction paradigm. We also introduce multiwidgets, which allow the direct control of multiple virtual widgets without the need to change the state of the device or use modifier buttons. This approach to input does not depend on material displayed visually to the user, and, thanks to tactile guidance, may be used by expert users as an eyes-free user interface. We believe that these benefits make this interaction system especially suitable for wearable computer systems that use a head-worn display and wrist-worn watch-style devices.","PeriodicalId":407425,"journal":{"name":"Eighth International Symposium on Wearable Computers","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127967425","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}

A large proportion of this type of research so far has been carried out with carefully positioned accelerometers, resulting in fairly good recognition rates. An alternative approach targets a more pervasive sensing vision where the clothing is saturated with small, embedded sensors. By increasing the quantity of sensors, while decreasing their individual information quality, a preliminary comparative study between the two approaches looks at the pros, cons, and differences in algorithm requirements.","PeriodicalId":407425,"journal":{"name":"Eighth International Symposium on Wearable Computers","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121617088","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}
