Development of a system to provide different fields of view to eyes with a function to generate rapid movements.

We developed a system that provides a human user with the artificial oculomotor ability to control their eyes independently, which was named Virtual Chameleon after Chameleons. Virtual Chameleon consists of two independently controlled CCD cameras, a 3D tracking sensor system and a head-mounted display. The Virtual Chameleon control independently postures of two cameras to follow the sensors of the 3D tracking system smoothly.

A portable device to represent different views to both eyes.

To investigate the flexible adaptation of human visual system, we developed a system to provide different view fields to both eyes of a user respectively. The system named "Virtual Chameleon" consists of two CCD cameras independently controlled and a head-mounted display was used by twelve healthy volunteers. Eleven of them became able to independently control visual axes and understood two different views.

Activation of caspases and apoptosis in response to low-voltage electric pulses.

Few studies have examined apoptosis induced by low-voltage electric pulses (LVEPs). LVEP-induce changes in membrane potential that are below the membrane breakdown threshold and increase membrane permeability without electroporation (pore formation) through the transport of extracellular substances via phagocytosis. We demonstrated that propidium iodide uptake and apoptosis increased in accordance with the duration and number of LVEPs in B16 cells, which showed relatively good viability under mild electric field conditions.

Development of a wearable surveillance system using gait analysis.

An aging society is a reality in developed countries. An aging population requires more healthcare workers and facilities. To reduce this social problem, it is worthwhile to develop a wearable computer for elders or patients to watch over them.

Patient Record Information System (PaRIS) for primary health care centers in Indonesia.

This study explores the Patient Record Information System (PaRIS) for primary health care centers in a developing country such as Indonesia. The specific geography of the thousand islands country Indonesia is the reason for transportation difficulties as well as communication problems. This causes a serious adverse effect on the public healthcare service especially in the rural area within the country.
