, 2018 Seit der Konzeption des Virtual-Reality-Headsets im Jahr 1968 argumentieren Forscher, der nächste Schritt in der virtuellen Realität ist nicht nur zu sehen und zu hören, sondern in virtuelle Welten auch fühlen zu können. Ein Ansatz solch haptisches Feedback zu geben ist die Verwendung mechanischer Ausrüstung, etwa Roboterarme, Exoskelette und ...

Advanced Functional Materials, EarlyView.The polymer wall stabilized dye‐doped liquid crystals (PWLCs) enhance the sensitivity of photoinduced molecular reorientation in dye‐doped LC systems. The PWLC with an invisible polymer wall successfully reduces the threshold intensity and functions as an optical limiter under the incidence of low intensity light laser source.
