The proposed design resolves the complexity associated with consonant modification, applicable to major Indic scripts by providing visual array of modified consonants upon the user's selection of a consonant. 60 participants went through the prepared performance test on the proposed input system and they all showed the improvement of performance after typing 16 sentences. The familiarity of the consonant layout and the ease of figuring out how the input worked played a key role in getting user acceptance. Future work is required to refine the design and further investigate on the acceptance among those who have lower level of literacy, and the comparison with other Indic input methods.","PeriodicalId":439699,"journal":{"name":"Mobile HCI","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129226682","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}

Two industry standard variable-reluctance actuators (enhanced voice-coil actuators with added mass for stronger output) were used in the study. The design parameters of an input were amplitude, duration, carrier signal, envelope function, and actuator. Eighteen participants evaluated the modeled patterns with the criteria of similarity to physical buttons and user preference. An adjective rating task was also accompanied to assess the subjective quality of the designed tactile effects. Experimental results unveiled several important guidelines for designing realistic and favorable button-click tactile feedback. The findings of this paper have implications for improving the usability of user interface components displayed on a touchscreen by means of haptic feedback.","PeriodicalId":439699,"journal":{"name":"Mobile HCI","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114749472","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 technique, that we have named naturalistic enactment, is appropriate for application scenarios that are not easily replicated in a laboratory setting and might cause risks to users or other stakeholders if used at a prototyping stage, as is often the case in the healthcare domain. We present and discuss the use of this technique after the recent introduction of a mobile application aimed at assisting geriatric nurses in attending emergency calls. The technique provided nurses with the experience of operating the mobile application in a naturalistic environment (e.g., high ecological validity), thus allowing them to identify adoption issues that they would have missed otherwise.","PeriodicalId":439699,"journal":{"name":"Mobile HCI","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128111250","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}

To some extent, these systems are able to reason about a user's situation by means of the measured data. However, their overall uncertainty in modeling human behavior leads to ambiguity. A language for the mediation of context information between the user and the system is required to enable the user to adjust the machine's interpretation of his context. We describe how keywords that are attributed to activities by users themselves can act as such a mediator. We present results of a study that investigates the nature of this context attributes. The results demonstrate that different users use similar keywords to describe similar situations and different keywords to describe different situations. Therefore, algorithms developed to evaluate the semantic relatedness of tags and resources within folk-sonomies can be applied to exploit knowledge about the users' contexts from the keywords they have assigned. We discuss a prototype that recommends mobile services by enhancing its model with the described keywords.","PeriodicalId":439699,"journal":{"name":"Mobile HCI","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128128194","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}

In such systems, the scale is unknown as it is impossible to determine the scale from a sequence of images alone. Implementing scale is vital for ensuring that augmented objects are contextually sensitive to the environment they are projected upon. In this paper we demonstrate a sensor and vision fusion approach for robust and user-friendly initialization of map and scale. The map is initialized, using inbuilt accelerometers, whilst scale is initialized by the camera auto-focusing capability. The later is possible by applying the Depth From Focus (DFF) method, which was, till now, limited to high precision camera systems. The demonstrated illustrates benefits of such a system, which is running on a commercially available mobile phone Nokia N900.","PeriodicalId":439699,"journal":{"name":"Mobile HCI","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130699433","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}

Two main problems are discussed in this contribution: the identification and localization of the crosswalks, performed by processing data acquired both from the camera and the accelerometers, and the design of an interaction paradigm specifically addressed to blind users. Experimental results, conducted both on a dataset of images and with blind users, validate the applicability of the proposed solution.","PeriodicalId":439699,"journal":{"name":"Mobile HCI","volume":"184 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133622565","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}

Flick is one of the most preferred screen movement methods for scrolling. To improve the usability of flick, this study evaluated various mapping functions for one-handed flick. Mapping functions are models that show the relationship between the velocity of input and the movement of the screen. They were established by combining four types of functions, linear, quadratic, log, and logistic, and three initial screen movement velocities at the maximum control velocity of the flick, 222, 444, and 666 mm/s. After being used to find targets on a contact list, the mapping functions were evaluated by measuring task completion time and ease of use. We recommend the linear function with 444 mm/s and the quadratic function with 444 mm/s or 666 mm/s as the mapping function for flicking.","PeriodicalId":439699,"journal":{"name":"Mobile HCI","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131876503","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}
