“Awareness” is the ability to be conscious of, feel, or perceive (Wikipedia). This implies vigilance in observation and alertness in drawing inferences from what one experiences (Merriam-Webster). The ultimate goal of awareness computing is to create computing systems that are themselves aware. This conference has been evolved from the International Workshop on Aware Computing (IWAC2009) in Aizu- Wakamatsu, Japan, the International Symposium on Aware Computing (ISAC2010) in Tainan, Taipei, the International Conference on Awareness Science and Technology (iCAST2011) in Dalian, China, iCAST2012 in Seoul, Korea and iCAST2013 in Aizu-Wakamatsu, Japan. The conference provides a forum for researchers, engineers, and scientists for discussing awareness computing and exchanging ideas, opinions, and the latest results in this emerging new field. Topics of interest include, but are not limited to, the following: A: Awareness Science: A1: Awareness mechanism and modeling A2: Machine learning and knowledge management A3: Pattern recognition and image understanding A4: Neuro-computing/perception/cognition A5: Fuzzy logic/granular computing/rough set A6: Agent computing/swarm intelligence A7: Awareness ontology and semantics B: Awareness Technology: B1: Context/situation/background/semantics awareness B2: Intention/emotion/preference awareness B3: Location/position/goal awareness B4: Power/energy/capability/resource awareness B5: Weakness/risk/danger awareness B6: Safety/security/privacy/trust awareness B7: Chance/opportunity awareness C: Awareness Related Applications: C1: Tele-communication/ubiquitous computing C2: Image/video/speech/signal processing C3: Overlay/P2P networking C4: Data/web/text mining C5: E-business/e-government/e-learning C6: Health/child/elderly care C7 Smart grid/transportation/public services C8: Device and automatic control C9: Cloud computing/internet of things C10: Cognitive radio
