1. Might A Tablet Be The Ideal Platform/UI for a Highly Complex Calculator? Jake Schwartz 1

2. 2 2009: HP Releases 12C & 15C Apps for the iPhone

3. 3 Apps Were Enhanced Beyond The Simple Voyager Emulator

4. Walter Bonin’s Projects 4 2008: “Imagine” 2010: 30b Repurposing

5. Further Enhancements Could Take Advantage of Their Host Platforms 5 No hardware manufacturing issues Plenty of processing power / speed Example 1: Free42 by Thomas Okken with significantly more program memory Plenty of memory Easy off-line storage for sharing user-generated data Example 2: 42S RPN Calc with larger display for more stack levels or more program steps

6. What About Apps on Tablets? 6 Larger touch screens could allow for enhanced simulated keyboards and screens Simplified menu “labyrinths” possible More data and/or graphics can be displayed at once

7. The HP18C from1986

9. Same Problem With the HP 50g

10. Proposed Back in 1989… 10 HP28S Left-side Keyboard

11. An “Extended” 50g Tablet Application The challenge would be to port calculators to tablet platforms and enhance them to take advantage of the increased “real estate” for bigger screens and keyboards Going farther than handheld hardware can go: More keys / fewer keystrokes More soft-keys for user menus Larger objects displayed More complex graphics Better input-forms Consider creating new advanced calc apps from scratch for the tablet environment
