• Mobile devices can be defined in different ways when they are looked at from different perspectives.
• They can be defined in terms of the services they offer or based on the level of functionality connected with the devices.
Mobile Devices

Mobile Devices Can be classified as following
1) Type of Mobile Devices 2) Use of Mobile Devices 3) Operating System for Mobile Devices
Mobile Devices
![Page 8: Challenges in HCI for Mobile Devices](https://reader031.fdocuments.in/reader031/viewer/2022012313/558a5a61d8b42a78468b4722/html5/thumbnails/8.jpg)
Interaction design (IxD) is a relatively new field in the category of computer science that defines the ways in which a person can interact with a computer system.
Interaction Design

Successful interactive designs should Consider
1) Consumer Perceptive 2) Usefulness 3) Users Need 4) Psychology 5) User Centric Design 6) Usable
Interaction Design

1) Limited Input Facility • Keyboard
>Space for Key Installation>Small Keyboard increase error rate>Effort to learn new typing method
•The Stylus and Touch Screen>Screen size of the mobile is small
•The Scroll Wheel>Navigate a mobile device menu in one direction, eitherhorizontally or vertically.>Use as push button to do specific function
Hardware Challenge

2) Limited Output Facility
• Screen>Most Commonly used output facility
•Audio>Good output facility for feedback message for user>Can be used in conjunction with graphic and text message
Hardware Challenge

3) Design for Mobility
• Power facility for mobile device >Display , RF unit, Keyboard, Memory. >power management unit which collects information in hardware so that the performance of the system is not degraded

• Designing interface for user from backgrounds and experiences.
• Designing interface which is Usable and affordable to a heterogeneous set of users.
• Portability is the main core of the design to meet the requirement of mobility.
Conclusion
