This chapter will briefly introduce the molecular design, synthesis, structure and properties, characterisation method and applications of adaptive polymers. There are many smart and functional materials, and adaptive polymers are one such example. This book mainly focuses on adaptive polymers and textiles. First, some concepts will be suggested and definitions of adaptive polymers and textiles are reviewed. Following that, the characteristics, structures and potential applications of adaptive polymers will be summarised. Developing novel smart adaptive polymers and textiles are challenging, and some future trends are suggested at the end.

Skilled work in a VR environment requires dexterity. Dexterity is more easily achieved by embedding the virtual world in the user's natural work volume than by immersing the user in a beyond-arm's-reach virtual space. We describe a cost-effective means of achieving this, with easily calibrated hand-eye coordination; a stereo display one looks and reaches into. We discuss the hardware and software environments, the calibration required, a test for the support of dexterity, and a preliminary application in the manipulation of medical images.
