APPLICATIONS OF MULTI-TOUCH TABLETOP DISPLAYS AND THEIR CHALLENGING ISSUES: AN OVERVIEW

Multi-touch tabletop displays provide a co-located collaborative workspace for multiple users around a physical table. They sit together and perform collaborative interaction to select and manipulate digital contents using their bare fingers. However, these systems bring a new paradigm shift in user interaction and present various challenges to design natural user interfaces respectively. The growing popularity of tabletop displays and their related issues have gained a greater attention among researchers in academia and industry. It creates a need to present an overview of multi-touch tabletop displays. This review paper attempts to present the touch enabling technologies that support in the construction of multi-touch tabletop displays. It also presents the important applications of multi-touch tabletop displays in different domains and their challenging issues in different perspectives. Finally, this paper proposes the future work
