This review describes or analyses the trends and best practices in Human Computer Interaction and Computer Vision. Human-Computer Interaction (HCI) is a computer user interface which the user of the system works with to achieve their given tasks and sees the system in use. Information Technology (IT) is essentially an integrated person-machine system that provides information support operations, management and decision-making. Human Computer Interaction (HCI) focuses on the interactions between human and computer systems to achieve the IT system functionality, user experience, usability, the support of user interaction effectiveness. Users are increasingly preferring the use of online business systems and so are becoming intolerant of systems which are not user friendly. The human factor is an attribute (physical or cognitive) which is specific to people that use a system and how it influences the normal operations of the system as well as the achievement of human-environment equilibriums.
Surface technology eliminates input/output devices through a touch sensitive feature which plays the role of input/output devices as a result of the merger between the physical and the virtual world. Through surface technology, the user eliminates the use of GUI mediums and reduces the gap between the physical and the virtual world.There are two classes of surface technology, one for the display and the other one which uses a touch sensitive mechanism for the interpretation of user signals. New approaches and methods are now needed in HCI to equip researchers with a better understanding of designing interactive systems. There are new interactive possibilities to be explored in audio-based mobile technology. The increasing popularity of smartphones has proved the portability, adaptability and ‘always on’ capability of geo-locative interactive systems. HCI bridges the gap between humans and computing devices with respect to observation of interactions, analysis of the involved interactions and the the human consequences of the interaction. The focus of HCI is the practice of usability which includes look-and-feel features, appeal, utility, efficiency, effectiveness and safety.

Surface technology
Surface technology eliminates input/output devices through a touch sensitive feature which plays the role of input/output devices as a result of the merger between the physical and the virtual world (Farooq, U., et al, 2011, p.25). Through surface technology, the user eliminates the use of GUI mediums and reduces the gap between the physical and the virtual world. According to Farooq, U, et al (2011, p.26), a user interacts with the digitalized world by just a finger touch by virtue of the surface technology. There are two classes of surface technology, one for the display and the other one which uses a touch sensitive mechanism for the interpretation of user signals. Farooq, U., et al (2011, p.26) points out that the display component can be built on the display platform. On the contrary, the user signal interpretation component is based on an image taken by image sensing cameras which are generally infrared based. In such a setup, cameras are adjusted in a manner that covers the whole screen. The three ways in which the infrared based sensing can be achieved are frustrated total internal reflection, diffuse illumination, and diffused surface illumination (Farooq, U., et al, 2011, p.26). Straight user communication can be provided by direct interaction with the screen which nullifies the use of input devices such as mouse or a keyboard. In this way multiple processing points are offered simultaneously, which is unlike a mouse that provides only one point where the cursor is being processed, whilst user interaction is being made available at a common time slice. Surface technology brings a complete revolution on how people interact with computers (Farooq, U., et al, 2011, p.27). This the technology which is now widely adopted on touch sensitive screens.
