Introduction

• The advantages of ubiquitous mobile computing are only accessible if systems are easy to use.

• The current expansion in smart phone usage began with the iPhone and its radically new user interface.

• Mobile computing systems place a premium on good human factors design due to the reduced size of displays.

Definitions

• Human Factors is a discipline of study that deals with human-machine interface. Human Factors deals with the psychological, social, physical, biological and safety characteristics of a user and the system the user is in.

• Human-computer interaction is a discipline concerned with the design, evaluation and implementation of interactive computing systems for human use and with the study of major phenomena surrounding them.
