Kouichi Katsurada is an associate professor at Toyohashi Tech’s Graduate School of Engineering with a mission to ‘humanize’ the computer interface. Katsurada’s research centers on the expansion of human-computer communication by means of a web-based multimodal interactive (MMI) approach employing speech, gesture and facial expressions, as well as the traditional keyboard and mouse.
“Although many MMI systems have been tried, few are widely used,” says Katsurada. “Some reasons for this lack of use are their complexity of installation and compilation, and their general inaccessibility for ordinary computer users. To resolve these issues we have designed a web browser-based MMI system that only uses open source software and de facto standards.”
The user can interact with the system by speaking directly with an anthropomorphic agent that employs speech recognition, speech synthesis and facial image synthesis.
For example, a user can recite a telephone number, which is recorded by the computer and the data sent via the browser to a session manager on the server housing the MMI system. The data is processed by the speech recognition software and sent to a scenario interpreter, which uses XISL (extensible Interaction Scenario Language) to manage the human-computer dialogue.
“XISL is a multimodal interaction description language based on the XML markup language,” says Katsurada. “Its advantage over other MMI description languages is that it has sufficient modal extensibility to deal with various modes of communication without having to change its specifications. Another advantage is that it inherits features from VoiceXML, as well as SMIL used for authoring interactive audio-video presentations.”
On the downside, XISL requires authors to use a large number of parameters for describing individual input and output tags, making it a cumbersome language to use. “In order to solve this problem, we will provide a GUI-prototyping tool that will make it easier to write XISL documents,” says Katsurada.
“Currently, we can use some voice commands and the keyboard with the system, and in the future we will add both touch and gestures for devices equipped with touch displays and cameras,” says Katsurada. “In other words, it is our aim is to make interaction with the computer as natural as possible.”

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
