Challenge in ‘HCI’ Design for Mobile Devices

Conclusion

“Human-computer interaction (HCI) is the study of

the interaction between people and computers”

Usable Receptive

Introduction to ‘HCI’

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?

Problem Statement

• 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

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

A) Hardware Challenges 1) Limited Input Facility 2) Limited Output Facility 3) Designing for Mobility

Challenge in HCI Design for Mobile Devices

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

Hardware Challenge

1) Hierarchical Menus

Software Challenge

Desktop Site Mobile Site

2)Navigating and Browsing

Software Challenge

3) Images and Icon

Software Challenge

Desktop Site Mobile Site

• 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

There are three key characteristics of interaction design process

User Focus

Specific Usability Criteria

Iteration

Conclusion
