INTERFACE COMPLEXITY OF PERSONAL DIGITAL ASSISTANT An empirical study of linear and non-linear menu By SANJAY KUMAR TRIPATHI November’ 2006 Head of the examination chair: Prof. Dr. Willi Petersen Chair: Prof.Dr. Heiner Dunckel Co-chair: Prof. Dr. Marianne Resch External- Chair: Prof. Dr. Susanne Maaß AbAbAbAbssssttttrrrraaaacccctttt Researches into usable interface of small screen portable devices are rare in academic field. The proposed study addresses the problems of interface complexity of ever becoming small devices. This thesis resulted from applied research using experiment based- empirical study on the use of small screen display interface of personal digital assistants. The whole study is carried out in the light of man- technology and organisation relationship. Small screen display interfaces are quite often used in specific organisational setting e.g.
