The book leaves the shelf. The wall turns the page.
Screens shrink the story. Walls give it room. SR1 stands the size of a pocket paperback, throws a living simsbook onto any surface, and scales the page from a bedside sketch to a community wall. Bluetooth opens the door, the phone lends the internet, and the whole qualped library walks into the room.
Portable projection sells USD 1.9 billion in 2025 and rides a 7.4 percent yearly climb toward USD 3.9 billion by 2035.1
A6 sizes the shell, the format of the pocket paperback: 105 by 148 millimetres, 32 millimetres deep, a target 460 grams in the hand. The spine wears deep navy anodize with a gold reading lamp of a lens. The fore-edge stacks forty aluminium fins, coated warm vellum, cooling the laser while reading as pages. Heat leaves the way pages turn.
Materials tell the same story the software tells: a book made of light deserves a body made like a book. Every surface below carries a job, a finish, and a reason.
Extruded aluminium takes a deep navy hard-anodize, shrugs scratches, and grounds the radios' antenna windows.
Forty thermally conductive fins wear a warm ceramic skin, cool the laser engine, and read as the pages of a closed book.
Sapphire resists the keys in the bag, passes the beam clean, and frames the optic like a jewel deserves.
Physical vapour deposition bonds real gold colour to steel, so the touchpoints keep their shine through years of thumbs.
A recycled polymer skeleton mounts the boards, damps the fan, and keeps grams off the scale.
Knitted fabric from recycled bottles lets the two drivers speak while the face stays soft and warm.
Silicone grips glass tables, wood shelves, and concrete sills, so the page holds still while the family moves.
The box opens like a slipcased first edition, prints with soy ink, and composts when the story starts.
Architecture stacks the way a signature folds: window, light, sense, think, power, breathe. Texas Instruments' 0.23-inch DLP micromirror class supplies the proven 1080p heart, and TI even calls its developer engine a board "the size of a sticky note."2 Everything below the window lists as a design target for the pilot build.
| SR1 target specification | |
|---|---|
| optical engine | 0.23-inch DLP digital micromirror, 1920×1080, TI DLP Pico class (the same family whose 1080p developer module drives 100 lumens from a Raspberry Pi)2; triple RGB laser targeting 700 ISO lumens |
| focus + geometry | voice-coil autofocus driven by an 8×8 time-of-flight depth array; four-corner auto keystone from IMU plus surface map; obstacle-aware framing |
| image | 15 to 148 inches diagonal, 1.0:1 throw, wall, table, floor, or ceiling |
| touch | infrared light field plus 60 fps camera for ten-point touch at reading sizes, the method Sony proved on the Xperia Touch67 |
| compute | octa-core Arm SoC with NPU, 8 GB LPDDR5, 128 GB UFS storage, on-device wake word |
| connectivity | Bluetooth 5.4 (pairing, remote ring, tether); IPv6 over Bluetooth LE per IETF RFC 76684 with mesh growth per RFC 91595; Wi-Fi 6E library lane; USB-C DisplayPort in |
| audio | two 3 W full-range drivers, passive radiator, three-microphone far-field array |
| power | 40 Wh battery, about 2.5 hours of reading light, USB-C PD 65 W charge and power-bank input |
| body | 105 × 148 × 32 mm (A6 format), target 460 g, laser safety engineered to IEC 60825-1 Class 1 |
Distance sets the size; the reader keeps the focus. A time-of-flight array maps the surface sixty times a second, drives the voice-coil lens, and squares the keystone before the eye notices. Move the lantern and the page follows. Throw runs one-to-one: one metre of air makes one metre of page.
Bluetooth handles the handshake; the page decides the pipe. Three lanes carry the library, and the reader picks the lightest lane that serves the moment.
Touch turns the page. Infrared light washes the wall, the 60 fps camera watches the fingertips, and taps land like taps on glass, the trick Sony shipped at 23 inches in 2017.67 Voice carries the rest: QwaiAI listens on-device for the wake word and gives every page a voice.
"The book leaves the shelf. The wall turns the page. One lantern carries the library."
SR1 DESIGN THESIS ◆ QUALPED HARDWARE ◆ ONTARIO, CANADAPrototypes earn belief; schedules earn prototypes. Three phases move SR1 from bench to pilot line, and Durham Region supplies the bench while Ontario, Canada supplies the line.
