RE: Open problem: optimal calculator keyboard layout based on key usage statistics
Things I've found somewhat true after playing for a while with calculators:
  • The keys (if they're not on the fascia or keys) you need the most are often the ones buried the deepest in menus, or indeed the CATALOG (not looking at you, FACT.)
  • The function you've been trying to find for the past five minutes is the primary function on the second key over on the second row down, i.e. the key your eyes keep skipping over. (This one has personally bitten me more than once, on both the 50G and 9750gII)
  • Each person (presumably) may well use the calculator differently from anyone else, though you can at least model commonalities. This point is less likely for school children (all students solve the same problems using (roughly) the same keys) and more true for professionals.
