Introduction to HCIHuman-computer interaction (HCI) is the study ofthe interaction between people and computersUsableReceptive 4. Problem StatementInterface designers to make efforts to developinteractive mobile products that are Easy to Learn Effective to use Enjoyable User Experience 5. Problem Statementthis paper addresses the following research questions:1. What are the major challenges of designing interactive products formobile devices?2. What are the possible solutions to such problems in developing a gooduser-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? 6. Mobile Devices Mobile devices can be defined in different wayswhen they are looked at from different perspectives. They can be defined in terms of the services theyoffer or based on the level of functionality connectedwith the devices. 7. Mobile DevicesMobile Devices Can be classified as following1) Type of Mobile Devices2) Use of Mobile Devices3) Operating System for Mobile Devices 8. Interaction DesignInteraction design (IxD) is a relatively new field inthe category of computer science that defines theways in which a person can interact with acomputer system. 9. Interaction DesignSuccessful interactive designs should Consider1) Consumer Perceptive2) Usefulness3) Users Need4) Psychology5) User Centric Design6) Usable 10. Challenge in HCI Design for Mobile DevicesA) Hardware Challenges1) Limited Input Facility2) Limited Output Facility3) Designing for Mobility 11. Hardware Challenge1) Limited Input Facility Keyboard>Space for Key Installation>Small Keyboard increase error rate>Effort to learn new typing methodThe Stylus and Touch Screen>Screen size of the mobile is smallThe Scroll Wheel>Navigate a mobile device menu in one direction, eitherhorizontally or vertically.>Use as push button to do specific function 12. Hardware Challenge2) Limited Output Facility Screen>Most Commonly used output facilityAudio>Good output facility for feedback message for user>Can be used in conjunction with graphic and textmessage 13. Hardware Challenge3) Design for Mobility Power facility for mobile device>Display , RF unit, Keyboard, Memory.>power management unit which collectsinformation in hardware so that the performanceof the system is not degraded 14. Software Challenge1) Hierarchical MenusDesktop Site Mobile Site 15. Software Challenge2)Navigating and Browsing 16. Software Challenge3) Images and IconDesktop Site Mobile Site 17. Conclusion Designing interface for user from backgrounds and experiences. Designing interface which is Usable and affordable to aheterogeneous set of users. Portability is the main core of the design to meet therequirement of mobility. 18. There are three key characteristics of interaction designprocessUser FocusSpecific Usability CriteriaIterationConclusion 19. Thank you
