Augmented Perception for Diagnosis and Orientation Support

1 :envihab International Symposium Cologne, Germnay May 22-24, 2011 University of Applied Sciences for Diagnosis and Orientation Support Artificial sensors and their application in medicine and navigation Wolfgang Heiden 2011 Augmenting human perception Human perception...has been optimized by evolution for natural environments through thousands of generations;... is not optimized for modern technological environments and the exploration of extreme (terrestrial and extraterrestrial) habitats; low/high pressure, pollution, radiation, etc. quickly changing/varying sensory requirements... has a need for additional senses, but can't wait for evolution! look for a technical solution Problem: Use existing sensory channels for intuitive perception, but don't override direct sensory information! Wolfgang Heiden :envihab

2 Natural vs. artificial perceptive components NATURAL reality physical sensors biological (human) senses memory learned and remembered facts intuition and emotion ARTIFICIAL VR technology IR vision, thermography, ultrasound, radar, Geiger counter, chemical sensors,... AR technology, head-up displays, navigation support, background information... Wolfgang Heiden :envihab (AuPer) Physical Reality sensual reception Electro-magnetic field variation..., Radio, Microwave, IR visual UV, X-Ray,,... neural processing memory and intuition Chemicals visual gaseous fluid (solid) Pressure/density variation..., Infrasound audible Ultrasound,... Solid matter olfactory gustatory touch vibration force feedback (thermal) auditory haptic Cognitive Reality : Enhancement of human senses by transforming additional signals from physical reality to the sensory channels. Wolfgang Heiden :envihab

3 Supplemental realtime sensor: Thermographic vision Concept for a thermographic AuPer device partially superimposing visual and thermic spectrum semi-transparent mirror (reflecting IR) thermographic camera visual camera composite image Wolfgang Heiden :envihab Medical AuPer application: Diagnosis support Diabetic foot syndrome peripheral arterial occlusive disease in the lower limbs (realtime) superposition of real and thermografic images early diagnosis by detection of blood undersupply Wolfgang Heiden :envihab

4 Processing of cross-sensitive sensitive sensor arrays Visual color reception as a Linguistic Variable 3 color classes (fuzzy sets) red (L) / green (M) / blue (S) cross-sensitivity as overlapping membership functions Wolfgang Heiden :envihab Artificial sensor example: Electronic tongue FH Aachen, INB setup: immobilized sensor arrays sensitivity to heavy metal ions (Ag, Cu, Zn, Pb,...) in aqueous solution cross-sensitivity Wolfgang Heiden :envihab

5 Orientation in alien environments navigation in unusual habitats intuitive perception of varying (possibly dangerous) environmental conditions mobile AR device source: MEDAV, Uttenreuth, D supplemental information on see-through display (alternative: video display) Wolfgang Heiden :envihab in :envihab Extreme environments (outside and possibly also inside a closed habitat) may require perceptive abilities not covered by original human senses. Such devices can be developed and optimized in virtual simulation environments, but must eventually undergo physical simulation. EnviHab may serve as... testbed for AuPer efficiency training environment for AuPer applications application environment with special perception requirements for closed habitats Wolfgang Heiden :envihab
