Kajimoto Lab
Machine-translated · View original
A haptics lab that reproduces and conveys fingertip touch through electrical stimulation and vibration.
AboutAbout the lab
Reproducing fingertip touch with electricity and vibration.
The Kajimoto Lab researches how to create the sense of touch felt at the fingertips with machines and how to convey it.
Using electrotactile displays, which produce sensations by applying electrical stimulation to the skin, the lab investigates the feel of pressing a button and how the perception of touch changes with skin temperature.
The lab also measures how finely different locations on the fingertip can distinguish sensations, and applies the results to device design, such as electrode placement.
Key terms
- Electrotactile display
- A device that produces tactile sensations by applying electrical stimulation to the skin. It is lightweight and allows electrodes to be arranged at high density
- Discrimination threshold
- The limit value at which differences such as direction can be distinguished. The smaller it is, the finer the distinctions that can be made
- Sensation threshold
- The minimum intensity at which a stimulus begins to be felt

ResearchResearch themes
The lab studies how to artificially create, record, and convey fingertip touch to people at a distance. Centered on electrotactile displays, it also works on vibration-based presentation and tactile sensors.
*Illustrative imageMeasuring the Directional Discrimination Threshold Across the Whole Fingertip
The lab measures the limit at which differences in direction can be distinguished (the discrimination threshold) across the whole fingertip, from the joint area to the tip. Using an electrotactile display, it examines how the fineness of touch differs by region of the fingertip.
*Illustrative imageButton Feel Created with Electricity and Vibration
The aim is to give virtual buttons, which are spreading with touch panels and VR, a feel like that of physical buttons. In step with the pressing motion, electrical stimulation expresses the sense of the button being pushed in, and vibration expresses the click.
*Illustrative imageSensation Threshold During Sliding Operations
The lab investigated the relationship between the speed at which a finger slides across an electrotactile display and the intensity at which sensation begins (the sensation threshold). The results show that the longer the pulse width, the lower the threshold, and that speed also affects the threshold.
*Illustrative imageSkin Temperature and Electrical Stimulation Thresholds
A challenge of presenting touch with electrical stimulation is that stronger stimulation causes pain. The lab measures the thresholds for touch and pain sensation at normal, high, and low skin temperatures, seeking basic clues for presenting touch while reducing pain.
