How many hundreds of times a day do we tap our smartphone screens? Each time, our gaze drops to our hands, and the scenery and conversations in front of us are interrupted. But this "shoulder-mounted AI" breaks that spell. It's a small, badge-like device that attaches magnetically to your collar or shoulder strap. There is no screen.
All it has is an ultra-wide-angle camera, a microphone, and a directional speaker. This device "sees" the same things you're facing. Open the fridge and ask, "What can I make with this?" and it recognizes the contents and suggests recipes. Look at a sign overseas, and it instantly translates and reads it aloud to you. The few seconds it takes to pull out your phone and launch the camera app become "zero seconds." This is a revolution.

You're not wearing earphones, yet you hear a voice that only you can hear. Using the latest "directional audio technology (beamforming)," this device beams sound directly into your ear canal alone. The people around you can't hear it.
"Your next meeting is in 5 minutes." "It looks like rain, so bring an umbrella." It feels as if an invisible fairy is perched on your shoulder, secretly giving you advice. There's no stress of being startled by notification sounds—information flows in as natural conversation. For lonely modern people, having a "voice" that's always by your side brings a sense of comfort beyond imagination.
| Not "Search" but "Action." The Impact of LAM

Until now, Siri and Google Assistant excelled at "searching." But what's built into wearable AI in 2026 is the Large Action Model (LAM). This is an AI made for "action."
"Call me a taxi for the ride home." "Order my usual detergent." There's no need to open an app and tap a button. The AI calls Uber's API on its own and even completes the payment on Amazon. The concept of "switching between apps" disappears—you simply say what you want to do, and the world moves. You can offload all the tedious chores to your partner on your shoulder.
| Always Recording? The Privacy "Trust Light"

"It's scary having a camera always pointed this way." That's a perfectly natural concern. Whenever this device is recording or recognizing, a "Trust Light" glows green or red so that anyone can see at a glance. When it's not lit, the camera is physically off.
In addition, conversation data is masked for personal information by an on-device chip (edge AI) before being sent to the cloud. It's an attempt to solve the razor-thin balance between "convenience" and "surveillance society" through technology and design. Whether society accepts this new camera depends on its trust in this "light."
| Summary: Buying "A Life Where You Don't Look Down" for 100,000 Yen

The price is around 100,000 yen—about the same as a high-end smartphone. You might think it's expensive for something without even a screen. But this is not a phone. It's an expansion slot for your brain, a physical "second brain."
When walking through town, you look up at the sky and see people's faces as you walk. This is a device for reclaiming that ordinary humanity. If you're aware of your "smartphone addiction," this partner on your shoulder will be the ultimate companion for a digital detox. After all, the world is far more high-resolution and beautiful than what's inside your phone screen.
