Halliday (DigiWindow)

The Halliday glasses are display-first AI glasses built around DigiWindow: a roughly 3.5mm MicroLED projector on the inside of the upper-right rim that beams a monochrome green ~3.5-inch virtual display above the eyeline (a projection, not a lens waveguide), in ~35-gram conventional frames with no front camera, a touchpad, and an optional ring controller. Features include real-time translation (40 languages, demoed), notifications, navigation, a 'Cheat Sheet' teleprompter, and a 'proactive AI' Echo Mode. DEPLOY records it at pilot maturity: it launched via Kickstarter ($369 backer price, $489 retail) rather than full retail shipping. Its differentiator is the eye-projected display plus proactive AI, not eye-tracking (no eye-tracking is on record), and it has no camera. Cap-flag: the AI features and translation are demonstrated, and the ~8-hour battery is a vendor claim; verified shipping at scale is not yet established.

Specs

notes

• Verified: Halliday (founder Carter Hou) debuted at CES 2025. Its DigiWindow projects a small display directly at the eye from a tiny rim-mounted MicroLED module (no front camera). Real-time translation was demonstrated hands-on. Kickstarter (Jan 22-Mar 8 2025): ~8,023 backers, ~$3.31M raised.
• Maturity = pilot (cap-flag): Past pure announced/research (real device, hands-on, units reached some backers), but Kickstarter-funded with partial, QC-delayed fulfillment through 2025 and no broad mainstream review of a generally-available retail unit. PILOT, not commercial. Money raised is not units delivered.
• AI-substance: VENEER: The 'proactive AI' claim is the weakest-verified element: TechCrunch's CES hands-on explicitly states the AI ('Echo Mode') 'was not ready for testing yet.' The only AI-adjacent feature actually demonstrated was cloud translation; with no camera, multimodal scene-understanding is not physically possible. 'World's 1st proactive AI glasses' is marketing.
• Claimed but NOT verified: Echo Mode / proactive AI working as marketed (not testable at reveal); general retail availability of a fully-fulfilled QC-clean product; 8-hour battery in real use; 40-language accuracy beyond one staged demo; funding beyond crowdfunding; leadership beyond founder Carter Hou.
