Objective: This study aims to implement a non-contact gesture-based interface for presentation purposes and to analyze the effect of the proposed interface as information transfer assisted device. Background: Recently, research on control device using gesture recognition or speech recognition is being conducted with rapid technological growth in UI/UX area and appearance of smart service products which requires a new human-machine interface. However, few quantitative researches on practical effects of the new interface type have been done relatively, while activities on system implementation are very popular. Method: The system presented in this study is implemented with KINECT$^{(R)}$ sensor offered by Microsoft Corporation. To investigate whether the proposed system is effective as a presentation support tool or not, we conduct experiments by giving several lectures to 40 participants in both a traditional lecture room(keyboard-based presentation control) and a non-contact gesture-based lecture room(KINECT-based presentation control), evaluating their interests and immersion based on contents of the lecture and lecturing methods, and analyzing their understanding about contents of the lecture. Result: We check that whether the gesture-based presentation system can play effective role as presentation supporting tools or not depending on the level of difficulty of contents using ANOVA. Conclusion: We check that a non-contact gesture-based interface is a meaningful tool as a sportive device when delivering easy and simple information. However, the effect can vary with the contents and the level of difficulty of information provided. Application: The results presented in this paper might help to design a new human-machine(computer) interface for communication support tools.

Image making for a person is a way to improve various factors that can express oneself, such as appearance, impression, and confidence. In general, people use mirror or camera as a traditional method to make their own image or perform presentation exercises. Recently, as smart mirrors are widely used in various fields, attempts to use smart mirrors as image making tools instead of mirrors have been frequently made. Smart Mirror is considered as a suitable tool to provide image making service because it can attach various devices such as a camera and a microphone in addition to the main advantage of a mirror that it is easily accessible. In this paper, we present BuddyMirror - a smart mirror software that provides image-making service to users, and a dedicated mobile app for flexibly running the mirror software. BuddyMirror provides functions for presentation, mock interview, and styling service at the request of users, interworking with the dedicated mobile app. We also describe the techniques developed for implementing and activating each of the new services as a module of MagicMirror, a widely used smart mirror development platform. The developed mobile app enables users to deliver presentations to BuddyMirror or to download the recorded video for image-making services.

In this paper, we developed a low cost smart puck system that can interact with the intuitive operation of natural finger touches. The tangible smart puck, designed for capacitive tabletop display, has Arduino embedded processor which communicates only with the MT server. The MT server communicates both to the smart puck and the display server. The display server displays the relevance information on the location of the smart pucks on the tabletop display and handles interactions with the users. The experiment results show that the accuracy of identifying the smart puck ID was very reliable enough to use in practice, and the information presentation processing time is confirmed excellent enough compared to traditional expensive commercial products.

Polymeric micelles, supramolecular assemblies of block copolymers, are useful nanocarriers for the systemic delivery of drugs and genes. Recently, novel polymeric micelles with various functions such as the targetability and stimuli-sensitivity have been emerged as promising carriers that enhance the efficacy of drugs and genes with minimal side effects. This presentation focuses our recent approach to the preparation of functional block copolymers that are useful for constructing smart micellar delivery systems in advanced therapeutics, including chemo-gene therapy. Particular emphasis is placed on the characteristic behaviors of intracellular environment-sensitive micelles that selectively exert drug activity and gene expression in live cells.

This paper discusses the design and implementation of a human-oriented interface based on computer vision that efficiently controls presentation slides. The user does not have to be confined to a keyboard or mouse any more, and can move around more freely because slides for presentation can be up and down using a general laser pointer that is used for presentation. Regions for virtual buttons are set on the slide so that the user can conveniently point the buttons using the laser pointer. We have proposed a simple and efficient method that computes the button areas in the image without complicated calibration. The proposed method has been implemented based on Microsoft PowerPoint ; moreover it can be applied to other PowerPoint-like presentation softwares. Our method for human-centered slide control enables the user to give audiences a more interactive presentation in a natural way.

In this study, the new model of presentation remote controller in which has improved the conventional function and deteceted the level of human's tension on a real time basis is suggested and tested. Existing presentation remote controller was just used turning the pages. But new model controls presentation and check tension level on real time using the smart phone's bluetooth interface. The proposed system is comprised with the PPG (Photo-Plethysmo-Graphy) sensor, Bluetooth and Wi-Fi modules. The configured system is to process (within 150 ms) the pulse signals of the presenter and stored the data. As a result, it can check and make up for the week presentation part and used as sources for improving self-confidence. This is the result obtained from the process of capstone design irregular course for 20 weeks of a graduate-to-be in four-year college.

Objective: The goal of this study is to design a creative tutoring service, which helps children gain confidence and creativity through learning activities. Background: Nowadays most kids are growing up in a very competitive environment under their parents' zeal for education. A stressful environment can deter a child from the confident undertaking of challenges, leading to depression, anxiety, and feelings of inadequacy. Art therapy helps children work through these issues, however the process led by instructors or parents, and kids still feel anxious studying adults' face to read their thought. Method: To help children address challenges, a creative tutoring service application can provide images with certain tasks instead of asking them to fill in blank areas. The tasks asked by the service system are 1) to visualize children's own experience utilizing visually associated images from given images and 2) to create an illustrated story modifying and re-composing given images. Another task is to learn basic math and words with numbers and alphabets in customized colors. By completing each task children collect awards, which allow them graduate to higher levels of challenges. The outcomes from the tasks are sent to the main server system and reviewed by analysts. Those results are sent to children's parents as a text message on smart phone. Results: Visual implication using images inspires children to make creative stories based on their own experience. Also, children can find their own patterns of reaching answers by using synaesthetic imagery through repetitive practices of creative thinking tasks. Conclusion: Understanding how they feel about doing tasks in certain environments and assessing them in varied situations should be carefully considered when designers approach service design for kids. By focusing on how to tutor children in creative ways, as opposed to focusing on the expected outcome, creative service applications can be designed to reduce children's stress and encourage self expression. Children are predicted to gain confidence through using the service without the concern of comparison by others. Application: The creative tutoring service needs to be developed and tested by varying types of children.
