Human Information Engineering Lab
Machine-translated · View original
A lab that develops interfaces that make use of human senses, such as illusions.
AboutAbout the lab
Building technology that supports people, starting from the mechanisms of sensation and movement.
The Human Information Engineering Lab (Maeda Lab) studies the mechanisms of human sensation and movement and develops systems that make use of them.
Humans obtain information through senses such as vision and hearing, and act on the outside world through movement using their muscles.
The relationship between sensation and movement can be analyzed quantitatively as the input and output of information.
The lab explains that, unlike hallucinations, illusions are a normal brain function that occurs in anyone, and that using them makes it possible to guide behavior naturally.
The lab also works on the transmission and sharing of sensations, which allows a person to experience what a distant person is seeing or touching.
Key terms
- Illusion
- A phenomenon in which one perceives something different from reality. Unlike hallucinations, it is a normal brain function that occurs in anyone
- Video see-through HMD
- A head-mounted device that shows the outside world by displaying camera video on a display in front of the eyes
- Vestibular organ
- An organ in the inner ear responsible for the sense of balance
ResearchResearch themes
The lab investigates the mechanisms of human sensation and movement and studies interfaces that support human behavior. It also develops devices and conducts psychophysical experiments for behavior guidance using illusions and for the transmission and sharing of sensations.
*Illustrative imageA system for sharing another person's field of view
This is a system in which two people wearing video see-through HMDs share the video the other person is seeing, along with where and in which direction the other person is looking. One cited application is skill transmission: by imitating an expert's movements, even the "knack" that is hard to put into words can be conveyed.
*Illustrative imageSensation of acceleration through galvanic vestibular stimulation
A weak electric current is passed through electrodes behind the ears to stimulate the vestibular organs of the inner ear and create an illusion of acceleration. The lab explains that the device is simple and compact, so it is easy to carry and operate.
*Illustrative imageA device that conveys tactile sensation from above the fingernail
When a vibrator is attached to the nail and vibration is applied while tracing an object, an illusion of unevenness arises. With this illusion, tactile sensations such as "bumpy" and "rough" are reproduced, and on the finger pad side the tactile sensation of the real object can be obtained at the same time.
*Illustrative imageIllusions when tracing with two fingers
When a condition is applied to the finger pads and a flat surface is traced with two fingers, an "opening-closing illusion" occurs, in which the fingers feel as if they are moving apart or closer even though the distance between them does not change. When the same vibration is applied to both fingers, it can also be felt not as a bump but as a "step."
