What the Halliday (DigiWindow) knows about you
Halliday, founded by Carter Hou, debuted its DigiWindow display glasses at CES 2025. Rather than etching a display into the lens, the roughly 35-gram glasses mount a tiny MicroLED projector, about 3.5 millimeters, on the inside of the upper-right rim to beam a monochrome green virtual display of about 3.5 inches directly at the eye, just above the normal eyeline, with no front-facing camera, control via a touchpad and an optional ring, and a claimed eight-hour battery. The pitch covers real-time translation in 40 languages, notifications, navigation, a Cheat Sheet teleprompter, and a proactive AI agent called Echo Mode, at $489 retail or $369 on Kickstarter, where it raised about $3.31 million from roughly 8,023 backers. The registry records it at pilot maturity, a deliberate cap-flag: it is past pure announcement, with a real device, a hands-on demo, and units reaching some backers, but it was crowdfunded, fulfillment was partial and QC-delayed through 2025, and no broad mainstream review of a generally available retail unit exists, so money raised is not credited as units delivered. On AI substance the proactive-AI claim is the weakest element, since TechCrunch's CES hands-on explicitly reported that the AI was not ready for testing, the only AI-adjacent feature actually demonstrated was cloud translation, and with no camera the device cannot do genuine multimodal scene understanding, so the world's-first-proactive-AI framing is treated as marketing.
