上游文通大学 Research Status of Human-Computer Interaction us,fast development ofproducts areusually accompanied with the increasing demand of the market. Apparently,the huge market demand of the keyboard and mouse was closely linked with the rapid development of the Internet. 4.Touch Technology From the PC age to the Internet age,interaction with the combination of mouse and keyboard did not change a lot.Until the appearance of smartphones and multi-touch technology,human-computer interaction stepped into the third generation,an era of fingertips,completely changing the traditional interaction styles. Development of touch screen technology was the impetus of this stage.Since the first touch screen PC-150 was created,touch screen undertook the evolution from resistive touch screen,capacitive touch screen,infrared touch screen,to the surface acoustic wave touch screen (Hotelling,Strickon, &Huppi,2010).Each technology had its own advantages and disadvantages,so the appearance of a new technology did not replace the old ones.However,another optical-touch technology,one could effectively prevent disadvantages of these technologies above,has been found,which could provide a better user experience.Recently,there was a research fever on optical-touch technology (Picciotto,Lutian,Lane,Fu,2012). Fig.4 Multi-touch technology With the development of touch screen,touch technology also progressed from single-touch technology to multi-touch technology,which triggered another huge reform of HCI.It has been widely used in large touch screen on occasions such as exhibition,entertainment and interactive meetings etc.We can predict that in the foreseeing future,multi-touch screen might replace all the old products.Keyboard and mouse will be even completely abandoned. 5.Multimedia and Multimodal Interaction Multimedia technologies that emerged in the late 1980s brought computer industry an unprecedented prosperity (Turk,2014).With the use of audio card,image card and other hardware equipment,it became possible that the computer was able to process sound,image,and video information.Thus,interaction technologies started to transfer into using sound,image and video.In this stage,other than mouse and keyboard,many other input and output devices suchas microphones, cameras,and trumpets,were gradually used for human-computer interaction.Interaction styles became more vivid and abundant than before. 6/19Research Status of Human-Computer Interaction 6 / 19 us, fast development of products are usually accompanied with the increasing demand of the market.
