• Open logic machine. III. Non-deterministic object feature representation via complexity evaluation

Publication Year: 1994, Page(s):283 - 288
| |PDF (520 KB)

A dynamic feature representation scheme is presented for non-deterministic objects with complicated images. Object symbols are dynamically generated through the interaction with computable scene in which the object feature is modeled in terms of stochastic contraction mappings from the image field. Through a series of simulation studies, the scheme is demonstrated to detect and regenerate fractal ... View full abstract»

In order to solve the problem that the amount of computer memories required for translating the non-segmented “kana” sentences into the “kanji-kana” sentences grows rapidly in proportion to the increasing of the length of the sentence, a new method of finding provisional boundaries of “bunsetsu” using 2nd-order Markov chain probability has been developed.

In addition to visual display, tactual-feedback system will play an important role in interactive computer interface design. Though the human visual system is generally more sensitive than the tactual one, the visual system is more subject to optical illusions. In this study, we have conducted experiments to obtain visual and/or haptical sensitivity of recognition of virtual figure features, such ... View full abstract»

| |PDF (368 KB)

Our concepts of biology, evolution and complexity are constrained by having observed only a single instance of life, life on Earth. A truly comparative biology is needed to extend these concepts. Because we can not observe life on other planets, we are left with the alternative of creating artificial life forms on Earth. I will discuss the approach of inoculating evolution by natural selection int... View full abstract»

• Advanced human integrated assembly system

Publication Year: 1994, Page(s):311 - 316
| |PDF (516 KB)

The concept of flexible production has been around for several years now. But why are there so few really flexible production systems around? The problem is that flexibility has usually been seen either as a technical or as a human factors issue. It is neither, but both. This paper discusses some questions related to reducing the time, risk and complexity of flexible production line design and cut... View full abstract»

• Cooperation and collaboration between actors and virtual models on stage

| |PDF (228 KB)

The employment of virtual human models interacting with actors is often used in science fiction and fantasy movies with sophisticated, off-line, 3D rendering tools. During the making of the movie the interaction between actors and models is limited. Because, when the action is recorded the actor is always alone and the interacting model is super-imposed on the film using special re-impression tech... View full abstract»

• Emotion and social factors in communication

| |PDF (380 KB)

Various new issues would arise if one wishes to create robots worth having as partners in the human society. Since these robots have to be able to communicate with humans more or less in equal standing, they need to understand human emotional expressions to some degree, as well as to produce some of them as if they owned their own emotions. This is because emotional expressions are indispensable i... View full abstract»

• Real-time mimicking of rhythm patterns using Lorentz plots

Publication Year: 1994, Page(s):101 - 105
| |PDF (284 KB)

Rhythm and its synchronization are important to natural interaction between humans and computers. For rhythm synchronization, computers must be able to understand human rhythm. Most previous work on teaching computers to understand rhythm has used programmed prior knowledge. Methods with no assumptions required large computer resources. This paper presents a system that understands any rhythm patt... View full abstract»

In a multi-agent system, problems are solved by the agents' cooperation, so communication among agents is very important and indispensable. Especially, the reliability of the communicated information is important. In this paper, a model consisting of many agents is introduced. Although in the model each agent has a limited ability and performs only its own duties, they cooperatively accomplish the... View full abstract»

Many researchers studied bilateral master-slave teleoperator systems especially after Anderson and Spong proposed a novel and simple method to overcome the instability due to transmission delays. In this paper the authors propose a bilateral master-slave manipulator system in which the slave impedance can be adjusted by the operator in a bilateral fashion. The stability of the system with time del... View full abstract»

A general method is developed to generate fuzzy rules by using genetic algorithms (GAs) and a fuzzy logic controller (FLC). By using GAs as a learning procedure and a FLC as the system's performance evaluator, the proposed architecture can construct an input-output mapping in the form of fuzzy if-then rules. The performance of the new architecture is compared with an artificial neural networks con... View full abstract»

It is necessary to know how quickly and how accurately humans can react when sensory stimulations are presented around them in order to construct a virtual reality system. We have been studying how quickly and accurately subjects can indicate targets such as a bursting sound and a flashing light presented around them without seeing their arm. The motion induced by the sensory stimulation is called... View full abstract»

| |PDF (392 KB)

When the scaled teleoperation is used, the stability issue becomes important due to the high gains in position or force scaling. We used two experimental methods to identify the stable region of position and force scaling factors of a one axis system having 4000:1 force scaling capability. We used a simple classical teleoperation control law. An indirect closed loop approach with ARX technique was... View full abstract»
