Life-long learning is a crucial but hard to balance demand in the face of competing demands of work and private life. Many life-long learners simply do not find the time or do not have the resources for intensive or immerse instructions. For this reason, life-long learners need to identify and exploit the breaks spread across different places and throughout the day/week and when other distractions are temporarily halted and attention can be diverted to learning. Yet another challenge is the curating of reusable personalized learning content and tools. Information overload is a much greater threat than information scarcity. There is a plethora of learning and informational content on the Internet, but there is also too much of it and the learners are flooded with information and tool choices. Losing control an focus often lead to non-satisfying learning experiences and may result in stopping all learning activities. Where the pain is one also may find the cure.

With mobile and cloud eco systems new heterogeneous kinds of informal learning are now available to life-long learners. Personal cloud reflects the "4S experience", consumers' desire to store, synch, stream, and share their content regardless of device or platform seamlessly, using multiple connected devices such as smartphones, media tablets, televisions and PCs over the Internet. Personal cloud services are not tied to one specific device or platform. An invisible experience means it works on anything. This personal info-cloud is centered on the individual; it provides continuous access, the content is organized for personal use and the applications and services are task, action and context aware.

JarkeI5-KoKl-0513-4Life-long Learning Life-long learning is crucial for achieving economicgrowth, competitiveness and social inclusion However, many issues exist– Information overload– Tools overload– Limited time– Hard to balance work and private life– Breaks for learning are spread across places and time– Limited attention– Learning is not the primary activity
  • Lehrstuhl Informatik 5(Information Systems)Prof. Dr. M. JarkeI5-KoKl-0513-5The Extended Mind Where does the mind stop and the rest of the worldbegin?*– Cognitive processes aren’t all in the head– Active externalism – the environment has an active casualrole in driving cognitive processes– Coupled system – the environment is part of the thought We all have minds that extend out into ourenvironments– Reliance, accessibility and trust* Clark and Chalmers (1998), „The extended mind,“ Analysis
  • Lehrstuhl Informatik 5(Information Systems)Prof. Dr. M. JarkeI5-KoKl-0513-6The Mind as a Cloud Is our cognitive state spread across theInternet? Humans are “natural-born cyborgs,” andthe Internet is our giant “extended mind” Move from just-in-case learning(memorization) to just-in-time learning(interaction) Through cloud-based mobile devices theglobal mind is effectively an extension ofour minds
