  1. E-Ink, Haptic Touch and MEMS Jake Schwartz

  2. Imagine a single handheld embedded with all HP calcs….

  3. Touchscreen Calc Proposals Before Circa 2000

  4. Touchscreen Calc Proposals Before, contd. 1989: HP28 functions on right of clamshell, Full touchscreen on the left

  5. Touchscreen Calc Proposals Before, contd. 1990s: emu48 2000: emu49 iPAQ version

  6. Touchscreen Calc Proposals Before, contd. 2009: HP Voyager Apps on the Apple iPhone

  7. The problem with those- No Tactile Feedback! • One solution: “Haptics” • Device vibrates when display is touched • However, they vibrate no matter where the screen is touched PLEASE VIBRATE!! PLEASE DO NOT VIBRATE!!

  8. Another recent technology: Electronic Ink • Extremely high contrast • Display remains “on” until modified Samsung e-reader Samsung Alias 2 mobile phone with E-Ink keyboard

  9. Electronic Ink, Continued In 2005, Tim Wessman’s proposed calculator with E-Ink display surface around the keyboard keys was the winner of HP’s Design-A-Calculator contest

  10. The Case For MEMS (MicroElectroMechanical Systems) TI DLP Chip Example: An Array of Swiveling Mirrors

  11. The Case For MEMS, continued • Consider an imaginary MEMS device consisting of an array of “Surface Elements” • Each is touch sensitive and has a size of 75-by-75 to the inch • Each contains an addressable 4-by-4-pixel E-ink display on top (net 300 dpi) • Each may be either “disengaged” or “engaged” • When engaged, surface exhibits miniature “oilcan” snap effect when pressed Close-up of a single “Surface Element” (“SurfEL”?)

  12. The Case For MEMS, continued • Software would specify groups of SurfELs to be engaged at the same time, • with each group acting as a keyboard key, and labeled as such on the • display on top • Like on the iPhone app, • the top of the screen • could act as the display • with the lower portion • acting as the keyboard • When disengaged, the • screen could be written • on with a stylus, if • desired

  13. The “Final Fantasy” • After turning on the application, it asks the user to choose the series • Then it requests to choose the model
