Resumen
The study aims to determine the impact of human-computer interface design on the development of mobile phones. The researcher used the descriptive analytical approach. The result shows the importance of smartphone such as communication with others, define the most important standards of application design such as efficiency and speed and determine the disadvantages of smartphones such as sleep problems and fatigue. In addition to, the study defines the HCI as science examines the design and use of computer technology, focusing on interfaces between people (users) and computers and determine the popular challenges which face HCI such as HCI designers face important challenges in how to ensure their design provides good HCI. The study recommended the need for further studies that support mobile phone and to deal with new platforms for iOS and Android, making usability tests for programs, applications and websites and qualify and train users with cognitive deficits in an appropriate manner to enable them to make better use of programs and applications.
