Transforming Calculators: The Future of Complex Calculating on Tablet Platforms

The potential of tablets as an ideal platform for complex calculators is explored. With powerful processing capabilities, ample memory, and enhanced user interface features, tablets can revolutionize how we interact with calculators. Notable examples include apps like Free42 and 42S RPN Calc, which leverage tablet advantages such as larger screens and improved layouts. Despite historical limitations with handheld devices, tablets present opportunities for richer user experiences and innovative features. The challenge remains to effectively adapt these applications for tablet use, maximizing functionality and engagement.

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

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

  3. Apps Were Enhanced Beyond The Simple VoyagerEmulator 3

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

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

  6. What About Apps on Tablets? • 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 6

  7. The HP18C from1986

  8. 18C Menus

  9. Same Problem With the HP 50g

  10. Proposed Back in 1989… 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
