2 Outline Backstory Platforms SE Research Areas [1] Universal Interfaces Software Reuse Need for Self-Adaptive Requirements Future Questions for Midterm

3 Backstory "Wild" growth in smartphone market First computer for many people Increased adoption of web-based services through mobile Users spending a chunk of time on mobile We have an app for everything now! Vamsi Raju CS 791Z - Topics on Software Engineering 3/26

4 Bottomline Mobile deserves it s own branch of Software Engineering Vamsi Raju CS 791Z - Topics on Software Engineering 4/26

5 Platforms Android ios Blackberry Windows Phone Vamsi Raju CS 791Z - Topics on Software Engineering 5/26

6 Android Fragmented OS - {2.1, 2.2, 2.3, 2.3.3, 3.0, 4.0, 4.1, 4.2} Different Devices - {size, hardware, color} Solving Android s problems = Solving everybody else s * Vamsi Raju CS 791Z - Topics on Software Engineering 6/26

7 * Except Windows Metro is a disaster Who needs two Dropbox apps in the same PC? Some problems are self-inflicted and need not be solved. Vamsi Raju CS 791Z - Topics on Software Engineering 7/26

8 Reiterate Mobile is at a nascent stage Too many problems We should be picky in what we want to solve Vamsi Raju CS 791Z - Topics on Software Engineering 8/26

9 SE Research Areas [1] Universal Interfaces Software Re-use Self-Adaptive requirements Vamsi Raju CS 791Z - Topics on Software Engineering 9/26

10 Universal Interfaces Simple tricks like scaling are not effective. Vamsi Raju CS 791Z - Topics on Software Engineering 10/26

11 Side Nav bar Vamsi Raju CS 791Z - Topics on Software Engineering 11/26

12 Pull down to refresh Vamsi Raju CS 791Z - Topics on Software Engineering 12/26

13 Software Reuse PC Era - Develop only for Windows Mobile Era - Website + ios + Android + Android + Windows + above Managing multiple codebases is an issue. Current solutions: Phonegap Vamsi Raju CS 791Z - Topics on Software Engineering 13/26

14 Need for Self-Adaptive Requirements Battery life Processor speeds Front camera Display size Active Radios Location of device Fluctuating power levels Vamsi Raju CS 791Z - Topics on Software Engineering 14/26

15 Non-functional requirements cannot be rigid for mobile devices. Current solutions: SDK s take care of most issues for native apps. Vamsi Raju CS 791Z - Topics on Software Engineering 15/26

16 Future Wouldn t it be great if we have solutions ready for tomorrow s problems? Vamsi Raju CS 791Z - Topics on Software Engineering 16/26

17 My Divinations! Vamsi Raju CS 791Z - Topics on Software Engineering 17/26

18 Convergence Convergence of operating systems is the future Mobile + Desktop + Tablet Different form factors share a single operating system Vamsi Raju CS 791Z - Topics on Software Engineering 18/26

19 No not Metro! It s actually diverging Metro and Desktop interface in the same operating system Maybe Windows Blue will be different Vamsi Raju CS 791Z - Topics on Software Engineering 19/26

20 Maybe Ubuntu... Ubuntu for Desktop Ubuntu for Phones Ubuntu for Tablets Ubuntu for Android Ubuntu for TV Vamsi Raju CS 791Z - Topics on Software Engineering 20/26

21 Or Google... Chromebook Chrome Android Vamsi Raju CS 791Z - Topics on Software Engineering 21/26

22 Definitely Apple! * *Speculation No signs of convergence right now ios and OSX are different Remember PowerPC to Intel transition Vamsi Raju CS 791Z - Topics on Software Engineering 22/26

23 (Important) 2 Consistent user experience on multiple form factors Code reuse for apps on multiple form factors Adaptive requirements for multiple form factors Right now mobile apps aren t complex. We have Software Engineering processes for Desktop apps We ll need solutions in the future when they converge Vamsi Raju CS 791Z - Topics on Software Engineering 23/26

24 Questions for Midterm Name three important areas for research in Software Engineering for mobile app development. What are self-adaptive requirements and why are they necessary? Vamsi Raju CS 791Z - Topics on Software Engineering 24/26
