Thermo-Haptics in Virtual Reality

In the era of ubiquitous computing with flourished visual display in our surroundings, the application of haptic feedbacktechnology remains in its infancy. Bridging the gap between haptics technology and real world to enable ambient haptic feedback on variousphysical surfaces is a grand challenge in the field of human-computer interaction. To create immerse experiences in the virtual world, weneed to explore different human senses (sight hearing, smell, taste and touch). Haptic feedback has an important role in virtual reality andenhancing immersion of user experience. Many different devices have been developed by both industry and academia towards this aim.Although tactile senses are important in daily life because actual contact is how a variety of tactile information is received, current virtualreality technology mostly uses visual and audio senses to physically reproduce the virtual environment. Thermal displays are designed todisplay thermal indications to make object detection easier in virtual environments. A foundation for analyzing the design of thermal displaysis supplied by thermal perception and the mechanism that underlies the processing of thermal information. A vast amount of research onthermo-haptic devices and functional materials has come together to create the basic framework for the creation of wearable thermal virtualreality systems. An overview of thermal perception, different physical mechanisms, and research that may be used in thermal virtual realitytechnology in the future is given. The review's conclusion examines the advantages and limitations of utilizing thermal display in virtualreality.
