CES 2026 Highlights
Mentoring2: A Smart Ring That Visualizes Emotional Rhythm
Mentoring2 uses four types of sensors and a proprietary algorithm to visualize continuous changes in daily condition, expressed as accumulated trends over time. By translating biometric signals into gentle insights, the system helps users notice how their energy and emotional state shift from moment to moment.
The goal is not to suppress, optimize, or diagnose these changes, but to accept them. MENTAGRAPH believes that awareness itself is the first step toward freedom—allowing individuals to design their actions in ways that feel true to themselves.
The ring features a refined, minimalist form created by NAOTO FUKASAWA DESIGN, led by internationally renowned designer Naoto Fukasawa. Designed to blend naturally into both professional and everyday settings, Mentoring2 quietly accompanies users throughout the day, supporting well-being without intrusion.
MENTAGRAPH plans to extend Mentoring2 beyond organizational use and into consumer-oriented services, integrating emotional awareness seamlessly into diverse lifestyles.
Relaxonic Cover: Creating Quiet Moments of Restoration
‍Visitors to the booth can experience Relaxonic Cover, an eye-mask device that gently envelops the eyes with ultra-high-frequency sound and soothing warmth. Designed for short breaks in busy environments, Relaxonic Cover offers a calm, private moment to reset and reconnect with oneself.

Product Overview

Mentoring2 Smart Ring & Mental Battery Service

Mentoring2 is a ring-type wearable designed for everyday daytime use. By continuously sensing biometric signals, it helps people notice subtle shifts in their emotional and energetic rhythm throughout the day.
Paired with the Mental Battery app, these signals are translated into intuitive visualizations that gently reveal one’s current state and support moments of pause and rest—without judgment or instruction.
Rather than reacting to numbers, the experience encourages awareness, acceptance, and a reconnection with one’s own pace.

DesignDesigned by NAOTO FUKASAWA DESIGN, Mentoring2 adopts a signet-ring silhouette that blends naturally into both professional and everyday life.The refined, compact form is intended to feel familiar and unobtrusive—quietly accompanying the wearer across different moments and lifestyles. The ring is available in seven sizes.
‍
TechnologyMentoring2 measures biometric signals using four types of sensors:
・Electrodermal activity (EDA)
・Photoplethysmography (PPG)
・Peripheral temperature
・Motion data (accelerometer and gyroscope)

Using these inputs, MENTAGRAPH’s proprietary algorithm visualizes continuous emotional and energetic trends that are difficult to perceive through momentary self-awareness alone.
Biometric data is transmitted from the ring to the app at three-minute intervals, allowing users to stay gently attuned to changes in their condition as they unfold.

Executive Comment
Jun Adachi, CEO of MENTAGRAPH Inc., commented:
“Our moods and energy are constantly shifting, often without us realizing it. At MENTAGRAPH, we believe that gently noticing these signals can open a path to greater freedom.
Our goal is not to tell people how they should feel or act, but to offer quiet support—technology that helps individuals accept their own rhythm and make choices that feel authentic to them.
