Design

PIM is by definition personal. It means that the user should not be restricted by models provided by others.

Consequently, making the choice to design your own PIM makes a lot of sense. Yet re-inventing the wheels is not necessarily a good thing. This page will thus provide help for those who wants to build their own system and still be efficient.

Cognitive limitations

One can imagine the role of this effort as

• the function present(linearize(objective_filer(complex world), brain limitations)))
• of "finding and transforming cognitive flaws to software support in an integrative fashion".
• the epistemic process of
  1. listing cognitive limitations based on state of the art in brain research
  2. finding and designing software solutions to efficiently cope with the listed limitations
  3. iterating while judging the impact of the solutions implemented

Consequently this could be split in 3 parts:

1. brain limitations
   • memory (STM, LTM, ...)
     • The Magical Number Seven, Plus or Minus Two: Some Limits on Our Capacity for Processing Information, G. A. Miller, 1956
   • attention
     • A Unified attentional bottleneck in the human brain, PNAS August 2011
   • decision making (bias, ...)
     • Capacity limits of information processing in the brain Trends in Cognitive Sciences 2005
   • underlying physical details of the limitations (to distinguish trends)
     • How Smart Can You Get?: Your Brain and the Limits of Intelligence by Vijay Balasubramanian, Santa Fe Institute August 2011
     • The Limits of Intelligence by Douglas Fox, Scientific American June 2011
       • How Physics Limits Intelligence by Douglas Fox, Scientific American Podcast June 2011
     • Metabolic cost as a unifying principle governing neuronal biophysics, PNAS 2010
2. brain alteration through interaction with software (eventually leading back to new brain limitations)
   • Human bandwidth and the Design of Internet 2 Interfaces: human factors and psychosocial challenges, 2000

3. software and hardware advances
