A research team has designed and implemented a group motivational interviewing system using multiple chatbots to support premenstrual syndrome (PMS), a common disorder among women. The system consists of a facilitator bot and two peer bots, and simulates a group counseling environment for PMS management. These findings provide valuable insights into the use of multiple chatbots for addressing mental health issues.

Researchers at Electronics and Telecommunications Research Institute (ETRI) have developed a new transparent film that stably disperses graphene. The film’s transparency changes depending on the intensity of light, and is expected to be used in a variety of fields, including laser protection devices, smart optical sensors, and artificial intelligence (AI) photonic materials.

Despite advances in machine vision, processing visual data requires substantial computing resources and energy, limiting deployment in edge devices. Now, researchers from Japan have developed a self-powered artificial synapse that distinguishes colors with high resolution across the visible spectrum, approaching human eye capabilities. The device, which integrates dye-sensitized solar cells, generates its electricity and can perform complex logic operations without additional circuitry, paving the way for capable computer vision systems integrated in everyday devices.
