    The use of emergency notification systems (ENS) to enhance the security, health, and welfare of older adults living alone has become generally widespread in. However, these systems, although widely available, tend to be underutilized. In order to address this problem, a model to improve the acceptance and use of information and communication technology was studied. Variables including usefulness, understanding of services, frequency of support contact, rescued experience, and willingness to use were surveyed using 265 actual ENS situations. The results indicated that willingness to use is affected by the perception of usefulness and understanding of service (p = 0.001). Additionally, results indicated that understanding is promoted independently by the communication of service-initiated support contact by phone (p = 0.001). Therefore, the support contact could be an effective intervention that promotes users ' willingness to utilize the service.

    In this paper we investigate whether interactive attention should be achieved jointly between a human and a vague embodied robot. It is known that joint attention by means of eye-gazing, finger-pointing or other verbal or non-verbal indication between humans plays an important role in making conversation smoothly and fulfilling sympathy for each other.While the effect of joint attention has been proved between humans and robots, the purpose of our paper is to realize interactional alert between a human and an vague embodied robot by using demonstrative pronunciations such as "this" and "that" referred by the robot as well as its physical distance and position from the human participant.

    The purpose of this work is to reduce the target pages of the web usability evaluation by usability testing. The target pages will reduce by detecting low satisfaction web pages. We analyze users ' interaction data for detecting low satisfaction web pages using variable selection. Analysis results, detectable interaction data are browsing time, moving distance of gazing points and wheel rolling. We apply statistical discriminant analysis to these interaction data and detect low usability web pages by classification between low usability group and others. Analysis result, we get mathematical line between evaluation target pages and low usability rate. Evaluators can determine evaluation target pages by using mathematical line of low usability group.

    Increasing the tourists is important at sightseeing spots. There are two types of reasons people visit sightseeing spots again: Because they are particularly interesting or something interesting was overlooked. The latter is based on a "feeling of regret." The feeling of regret can actually change people's behavior. The feeling of regret involves the difference between the ideal and reality, and the difference between the effort they put in and whether if feels successful or not. In psychology the "Zeigarnik effect" [1] states that people remember "unfinished or interrupted" tasks better than those they have completed. With sightseeing we consider the Zeigarnik effect to be involved in something a person wished to view or visit but couldn't. We predict the effect could be used induce people to want another chance, or that is, we think that they will wish to visit the relevant sightseeing spot again. The system proposed in this paper provides pictures and information in a gradual manner. In this paper we suggest how to get people to visit sightseeing spots again through the creation of "their sightseeing having been incomplete".

    People often read Web pages mainly designed for desktop or laptop computers with small screens on mobile phones or PDAs. But the mode switching between scrolling and other interactions may slow down the interaction when the user is interacting with spatially widely-spread information (e.g, navigating a Web page much larger than the real estate of the screen). In this paper, we present a new method to provide mode switching between scrolling and other operations, such as drawing, with one finger. When the user contacts on a touch screen with a pen or fingertip, the interaction is treated as the drawing operation. When the user touches the screen with the whole finger, the interaction is treated as scrolling. We developed methods to determine the finger 's contact status based on the contact area or subtle movements while the user 's finger stays on the screen. We also built a drawing application which allows the user to switch the mode between scrolling and drawing by the finger's contact status. Our small user studies showed that our methods can distinguish three different modes (pen input, touch with the fingertip, and touch with the whole finger) accurately.

    In this paper, we discuss the feasibility of conversational activation level estimation by using phonetic and turn-taking features. At first, we experimentally collected six groups of 3-persons conversational voice at three different activation levels. Then, we calculated the phonetic and turn-taking features, and analyzed the correlation between the features and the activity level. The analysis revealed that response latency, overlap rate and speech rate correlate with activation level and are less sensitive to individual deviation. Then, we formulate multiple regression equation, and examined the estimation accuracy using another six 3-persons groups. The results demonstrated the feasibility to estimate activation level at about 24% root-mean-square-error.

    This paper describes a method to model the change in vibratory perception due to the adaptation. In the vibration alert interface, user has to perceive the vibratory frequency correctly, however when the frequency was the same, the vibration perception was different if the frequency before change was different. Experimental results showed that the higher vibration frequency before the change is, the weaker vibration strength user perceives. In order to correct this difference of vibratory perception, we create a model to calculate the perception adaptation. Simulation result shows accuracy of this model.
