Cultural Dimensions in User Preferences and Behaviors of Mobile Phones and Interpretation of National Cultural Differences

The purpose of this study is to identify the differences in user behaviors and cultural tendencies which will develop a cultural evaluation frame work for mobile phone design among countries in the mobile telecommunication market. Cultural taxonomy helps the understanding of cultural differences. To help understand the Asian market more clearly, a brief overview of Geert Hofstedes findings (Individualism, Uncertainty avoidance, Power distance, Masculinity, and Long-term orientation) and the K.P. Lees Cultural Variables (Way of Task Handling, Temporal Perception, Conception of Nature, Adherence to rules, Relationship with Human, Nature of Human Activity, Message Contexting, and Expression of Emotion) for the index of different cultures was used in this study. This research is based on an online survey in three countries (Korea, China and Japan), summarizing the responses of questionnaire about user preferences, and behavioral perceptions of UI Design of mobile phones. The result of this research identified the differences and similarities among countries clearly, reorganized the cultural variables. After comparing values of authors value from online survey and two other variables, this study found that Hofstedes and KP Lees are very meaningful to identify cultural-based national characteristics. This verifies that differences of usage behavior and preference for mobile phone reflect cultural perspectives. This cultural research is the key to understanding these needs and to providing the companies with advanced market positioning. This study should not stop at a simple cross-national comparison but be a cultural comparison framework for giving companies a clear future direction for globalization-based design development.

Tangible user interface design for home automation energy management appliances

Home Automation System connects the digital technology and computers to the appliances at home and manages it. Its the frequency of use an position in the home that makes it important to have an aesthetic friendly user interface. There are numerous UI design cases of Display panel or the buttons. However, the usability or aesthetic sensibility design through using a variety of multi-layered emotional satisfaction of feeling that provides the interface design needs to be studied. This study explores the ways to satisfy the emotional needs of Home Automation System and Tangible User Interface (TUI).

MOYA: Interactive AI toy for children to develop their language skills

The main concept of MOYA, the interactive AI toy, is to provide an answer to the childrens curiosity about an objects name. MOYA is developed on the basis of four functionalities: hand motion tracking, image classification, robot motion control and graphic user interface. Raspberry PI, Ubuntu Mate OS, Arduino, OpenCV, TensorFlow, RealSense SDK and ROS are integrated for MOYA to accomplish some interactive tasks.

Introducing Smart Pillow Using Actuator Mechanism, Pressure Sensors, and Deep Learning-Based ASR

Sleeping is one of the most essential activities in human lives. It plays a vital role in good health and well-being of human lives. However, WHO (World Health Organization)s research shows that approximately 27 percent of worldwide population are suffering from sleeping problems, which may affect everyday activities. Amongst various sleeping aid products, pillows can provide the solution to alleviate sleep disorders, neck pain, and chronic fatigue. The adjustable or smart pillows in todays market have some limitations. For instance, there are only few fixed forms and there is only one way interaction from human to the smart pillow. We further improve the existing smart pillow technology in terms of higher transformability and better human-pillow interactions which is bidirectional, thanks to the actuator mechanism, pressure sensors and ASR system.

Buddy: Interactive Toy that can Play, Grow, and Remember with Baby

In a single-child household, babies lack peer experiences critical to their development and overall happiness. Likewise, parents are exhausted from work and childcare, so they often miss the most precious moments of their beloved babies.

Introduction of an Interactive Growing Robot/Toy for Babies

In this paper, we introduce an interactive robot/toy for babies, whose name is Buddy. As Buddy is a product for babies, its exterior is covered with combination of soft silicone and cotton for safety as well as ease physical interaction such as hugging with babies. Buddy is featured with its growing function, to accomplish true and deep interaction with babies. We designed Buddy to grow both physically and intellectually with babies, so that the babies can regard Buddy as their family or friendly peers. In addition, as Buddy will always be with babies, Buddy will act as a bodyguard as well as a keeper of valuable moments. We expect that Buddy will be a solution for issues associated with lonely babies resulted from social problems such as low fertility rate.

Researcher: A Reading Application Helping the Flow of Research in Tablet and Mobile Phone

With a growing digital environment, a huge quantity of digital content is being created and distributed quickly. Therefore, people from academia are under pressure to create and study such content. In addition, there are a number of reading applications supporting different functions and diverse platforms, which distract the flow of research. To solve this problem, we created a prototype reading app, Researcher, for the tablet PC and mobile phone, which helps the flow of research by providing cooperation among platforms, seamlessly circulating between consumption and creation of contents, prioritizing contents by context, and holding attention by multimodal input. We conducted an in-depth interview and survey to verify the effectiveness of the features and to find out the appropriate modality of input for the flow of research.
