"From handwriting analysis to pen-computer application",
Electronics And Communications Engineering Journal, June 1998, pp. 93..102
- Good Overview article on the problems of pen-computing development, though not specific on applications development.
- Pen-and-paper not a good metaphor for pen-computing electronic ink applications.
- Electronic ink as a (neglected) datatype in its own right: does not mention JOT standard of 1991.
- Refers to early research efforts (but not commercial efforts) in 1980s as focusing on booklet/portable units, pen gestures. States that Alan Kay's Dynabook had electronic paper in 1968. Claims pen-computing and communications in same unit first demonstrated by EO in 1993. Notes that training to 5,000,000 characters in the Unipen database is not enough to achieve good character recogntion. Mentions pen gestures.

"WACOM FID Presentation: Tablet PC: Pen input is back!",
Flat Information Displays Conference, Stanford Resources, Monterey, California December 12, 2001
- Techology/history review of resistive-film, electrostatic/capacitive, ultrasonic, and electromagnetic digitizers integrated with displays. Asserts that inductive (electromagnetic) digitizer required for hover/proximity (although Scriptel electrostatic did it, perhaps references is restricted to COTS components). Special section on integration problems of electromagnetic digitizer (rear-mounted) with display: inverter nosie/EMI shielding, power supply coil on motherboard, edge effects from metal frame. Special laboratory to re-calibrate digitizers incorporated with each display design. Mentions that Tablet PC spec requires proximity.

"Optical Position Determination on Plain Paper",
United States Patent Application Publication US2002/0158848 A1, October 31, 2002
- Similar to Anoto / Bennett / Sekendur, except does not use pre-printed pattern. Instead a CCD camera captures images of the surface as-it-is, and builds up a map of the image of the surface to use instead of the pre-printed pattern.
- CCD camera for optical digitizer is mounted on a gymbal / universal joint (sic), so as to be able to view the entire surface

United States Patent Application Publication US2002/0163511 A1, November 7, 2002
- Similar to Anoto / Bennett / Sekendur, except does not use pre-printed pattern. Instead a CCD camera captures images of the surface as-it-is, and builds up a map of the image of the surface to use instead of the pre-printed pattern. Specifically refers to the surface being the screen on a cell phone.

- Business model was to be a charge on all transactions that involved Anoto paper pattern, not directly on the licensing of technology
- Interview about Anoto with Christer Faehraeus, mentions comparison with Microsoft Tablet PC, which overshadowed their introduction at ComDex

- Resistive touch-screens use PET polyethylene terephthalate film with ITO Indium Tin Oxide resistive film. Reference to spacer dotes, similar to Scriptel. Capactive sensing can be front-mounted, but fewer layers than restistive touchscreen tablet digitizer. ClearPad (capacitive) and Spiral (inductive) digitizer tablets. Vague reference to proximity/hover sensing with CearPad capacitive digitizer.
- Defines touchscreen, ITO, PET Polyethylene terephthalate
