Editorial summaries

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.
