Based On Multi-touch Screen Human-computer Interaction Technology And Applications

With rapid development of Internet of Things (IOT) and its relative technologies, it has been used in wider fields, such as in fire monitoring, traffic management and so on. Large-scale display is the important equipment to show the huge amounts of information in the IOT system to the users. Without reasonable and effective human-computer interaction (HCI), only one-way information transportation from display to users is available. It makes the displays losing real-time and flexible reaction on user's demand and limits the fully usage of the information. Therefore, the research in HCI of large-scale displays can be great help for the promoting of IOT.This thesis studies the HCI of large-scale displays in the IOT systems and the practical application. An interaction solution based on multi-touch technique is provided. It establishes a two-way information interaction between display and users. The research objectives and main achievements in the thesis are listed as follows:◆Based on the contradiction between cost and technology maturity, this thesis presents a large-scale display interaction solution using intelligent terminal with multi-touch to achieve great stability, high precision and support multi-user. It also solves some shortages in HCI of large-scale multi-touch.◆Targeting on the practical application requirement and multiple development environments for display systems and terminals, a three-layer system architecture based on MVC model is presented. It owns expansibility and low coupling to meet the demand of diversity. With three-phase interaction protocol, terminals can collaborate with display by effective information communication.◆Aiming at different interaction scenes and models, visualization of information display and interaction of terminal are designed to be applicable to multi-touch control and massive information display.◆Combining with application requirements from fire information system, multiple source information display and interaction system is designed based on the solution, architecture and interaction of this thesis.
