We are pursuing "The form for human-friendly information." While an advanced information society has arrived with 21st century, information equipment and services are not necessarily friendly for the underdogs in society such as the elderly, disabled, children, and women. Therefore, we conduct research into system usability to mitigate the psychological and physical burden on users and afford users’ comfort. In other words, the key issue of our research is affective aspect of systems to support safe and comfortable social living.
In the 21st century, the kansei/affective values of industrial products are becoming very important. The Japanese word “kawaii”, which represents a kansei value, has such positive meanings as cute and lovable. Since few studies have focused on “kawaii,” we have systematically analyzed it for ten years and found rules as follows:

  • Round objects are more kawaii than shapes with straight lines.
  • Brightness and saturation are effective for kawaii colors.
  • Smaller objects are generally more kawaii.
  • Fluffy material has kawaii tactile sensation.
  • Kawaii feeling is divided into exciting kawaii and relaxing kawaii. The heart rate increases when watching exciting kawaii object.

Modern computer technology has enabled us to realize IoT (Internet of Things), or IoE (Internet of Everything), where a lot of “Edge Computers” such as wearable/implantable devices or sensors are connected to servers through computer network. In the near future, edge computers will be required to have more intelligence to extract knowledge from collected data on site, and to operate with very limited electrical energy obtained by energy harvesting. Our lab is conducting research and development of VLSI design technology for ultra-low power CPU. Through collaborative project with other universities, we have developed a 32-bit CPU chip (see figures) whose internal computing circuits are powered-off in a very fine-grained manner. Measured results of the test chip demonstrated that energy consumption was reduced by 21-35% as compared to the conventional one. In addition, we are studying VLSI circuit techniques to enable robust operation at very low voltage (e.g. 0.2-0.3V), and energy-efficient computer architecture/circuit to combine power-off control and non-volatile memory technology.

The vision of the Department of Information Sciences and Engineering is to cultivate individuals having the following skills, by facilitating a systematic and broad learning framework, specifically targeting, “Technologies leading to a flourishing human society and living by exploiting computers”.

  1. Basic academic intellect in mathematics and natural sciences including physics, essential for building a technology base.
  2. Acquire fundamental concepts and basic technological skills in information science and engineering, and creatively apply such skills.
  3. Designing and building skills in computer-based systems, taking into consideration the potential impact and feasibility of information technologies to society.
  4. Able to challenge problems independently considering the broad or global perspectives, capitalizing on in-depth academic intellect and noble personality traits.
  5. Communication skills with others as required by an engineer.

At the Department of Information Science and Engineering, we aim to provide education to allow students to learn technologies to enrich human society and lifestyles through computers in a systematic and broad fashion. Specifically, we aim to provide a good balance between core knowledge and applications of information technology, such as software, hardware, human communication, databases, and networks, through lectures and seminars, so that students can not only gain the abilities to create programs but accurately understand the principles underlying this technology, and then to foster the abilities to apply, develop, and create through contact with the latest research.

The Department welcomes the following types of students.

  1. Those who share the Department’s vision above and wish to better themselves through the education we offer.
  2. Those who have an interest in the foundations and applications of the information technology that sustains our advanced information society.
  3. Those who want to contribute to the development of society through utilizing and revolutionizing information technology.

Computers closely linked to Information Science and Engineering are now exploited by diverse, specialized industries. The graduates from the Department of Information Sciences and Engineering are engaged in firms specialized in a variety of fields exploiting computer system including system integrator for computer system design and development.
