Guidelines and principles for efficient interaction on large touchscreens with collaborative usage

Pekin, Tacettin Sercan
Understanding collaborative usage of large-size screen systems is important for advancing the general study of human-computer interaction (HCI) as well as for guiding the designers while creating efficient interactive large-size systems. This thesis aims to provide guidance for the designers of collaborative large-size screen systems. It therefore gives background information about such systems, defines similarities and differences in existing systems, compares existing design guidelines and principles, tests and validates proposed solutions and offers new guidelines and principles for designing interactive large-size screen systems. In the first part, a literature survey of input devices, output devices, interaction methodologies and collaborative interaction used for large-size screen systems was conducted. This showed that an empirical, systematic and academic study for guiding the design process of collaborative large-size systems is missing. Following a literature review of research methods in the HCI field, an initial system was setup, a gesture library was created and user interface (UI) elements were generated to gather initial findings. Existing design guidelines and principles of well-known platforms were compared and compatible ones were used as input for creating new ones. Thereafter, an empirical laboratory experiment with four major tests, was conducted to test interaction devices, multi-user interaction, collaborative usage and UI elements on a large-size touchscreen system. The results and conclusions of this research should help to inform the design and development of similar HCI systems. 


Comparison of cognitive modeling and user performance analysis for touch screen mobile interface design
Ocak, Nihan; Çağıltay, Kürşat; Department of Information Systems (2014)
The main aim of this thesis is to analyze and comparatively evaluate the usability of touch screen mobile applications through cognitive modeling and end-user usability testing. The study investigates the accuracy of the estimated results cognitive model produces for touch screen mobile phone interfaces. CogTool application was used as the cognitive modeling method. Turkcell Cüzdan application, which is suitable for the implementation of both methods, was chosen as the mobile application. Based on the feedb...
A usability evaluation framework and a case study on a supplier portal system
Babayiğit, Elif Fatma; Şen, Tayyar; Department of Industrial Engineering (2003)
The goal of this thesis is to provide a usability evaluation framework in the area of e-procurement technologies and a case study on this base. A survey of the concepts of human computer interaction, usability and usability evaluation techniques is carried out. Additionally current e-procurement technologies are explored and specifically a Company̕s Supplier Portal System which was employed in year 2003, as an e-procurement technology for the procurement of direct goods, is taken into consideration. Pointin...
Design and implementation of a plug-in framework for distributed object technologies
Kadıoğlu, Koray; Doğru, Ali Hikmet; Department of Computer Engineering (2006)
This thesis presents a framework design and implementation that enables run-time selection of different remote call mechanisms. In order to implement an extendable and modular system with run-time upgrading facility, a plug-in framework design is used. Since such a design requires enhanced usage of run-time facilities of the programming language that is used to implement the framework, in this study Java is selected because of its reflection and dynamic class loading facilities. A sample usage of this frame...
Scheduling approaches for parameter sweep applications in a heterogeneous distributed environment
Karaduman, Gülşah; Şener, Cevat; Alpdemir, Mahmut Nedim; Department of Computer Engineering (2010)
In this thesis, the focus is on the development of scheduling algorithms for Sim-PETEK which is a framework for parallel and distributed execution of simulations. Since it is especially designed for running parameter sweep applications in a heterogeneous distributed computational environment, multi-round and adaptive scheduling approaches are followed. Five different scheduling algorithms are designed and evaluated for scheduling purposes of Sim-PETEK. Development of these algorithms are arranged in a way t...
Comparison of hypermedia learning and traditional instruction on knowledge acquisition and retention
Yıldırım, Zahide; Aksu, M (2001-03-01)
A comparison was made of hypermedia learning environments and traditional instruction in terms of contribution to declarative, procedural, and conditional knowledge acquisition and retention in a specific subject area through a pretest-posttest control-group design. Thirty-nine 9th-grade biology students were assigned to experimental (hypermedia learning environment) and control (traditional instruction) groups through a matched-pair technique. Both groups were given pre-, post-, and retention tests. Postte...
