上海充通大学 Research Status of Human-Computer Interaction keyboard has been a hotspot.With the fast development of multi-touch technology,virtual laser projection keyboard and virtual keyboard appeared(Longe Van Meurs,2013).Virtual keyboards were mainly used in handheld devices,such as PDA,mobile phones,and iPad etc.Nowadays, people switch their attention from going for more advanced technologies used in the mouse to pursuing its more beautiful and unique appearance,suitable size,and satisfactory portability and comfortability (a) (b) (c) Fig.2 Schematic of the development of the keyboard (a)Traditional (b)Laser projection keyboard (c)Virtual keyboard 3.Mouse Graphical Display As graphical user interfaceappeared,the mouse was invented in 1964 by another American inventor Doug Engelbart (Myers,1998).Mouse was used to control the position of cursor on the screen and gave people much convenience.Its work principle was that the pivot in the mouse was driven by the ball at the bottom of the mouse,which in turn caused the variable resistance change to generate the displacement signal.These signals were then transmitted to the host.The emergence of mouse greatly facilitated interaction between human and computer,pushing us into the second generation of HCI.In this stage,mouse and graphical display were the main interaction tools,and characters, graphs,and images became the main interaction contents.Until today,as windows operating systems are widely used,mouse has been an indispensable input device.
