This document discusses challenges in designing interfaces for mobile devices. It addresses research questions about major challenges, solutions for user-centered design, and principles for mobile interfaces. Mobile devices can be classified by type, use, and operating system. Interaction design considers consumer perspective, usefulness, and user needs. Challenges include limited input/output facilities due to screen size and hardware constraints, as well as issues with menus, navigation, images, and power management for mobility. The conclusion emphasizes designing for diverse users, usability, affordability, and meeting portability needs through an iterative user-focused process.

Content Introduction to HCI Problem Statement Mobile Devices Interaction Design Challenge in HCI Design for Mobile Devices Conclusion
Introduction to HCI Human-computer interaction (HCI) is the study of the interaction between people and computers Usable Receptive
Problem Statement Interface designers to make efforts to develop interactive mobile products that are Easy to Learn Effective to use Enjoyable User Experience
Problem Statement this paper addresses the following research questions: 1. What are the major challenges of designing interactive products for mobile devices? 2. What are the possible solutions to such problems in developing a good user-centered design for mobile computing devices? 3. What are the principles of user interface design for mobile devices? 4. What are the new trends in mobile industry in the near future?
Mobile Devices 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
Interaction Design 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
Challenge in HCI Design for Mobile Devices A) Hardware Challenges 1) Limited Input Facility 2) Limited Output Facility 3) Designing for Mobility
Hardware Challenge 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, either horizontally 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
Software Challenge 1) Hierarchical Menus Desktop Site Mobile Site
Software Challenge 2)Navigating and Browsing
Software Challenge 3) Images and Icon Desktop Site Mobile Site
Conclusion 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.
There are three key characteristics of interaction design process User Focus Specific Usability Criteria Iteration Conclusion
Thank you
