Going native - Taking desktop applications to mobile devices

1,088
-1

Published on

How does a business make informed decisions around taking their desktop apps to the mobile world? Elan Tanzer will share some of the experiences in exploring which functionality makes sense to port to mobile devices, what the differences in human/computer interaction will be, and whether it makes sense to go native to each OS or to use a more portable solution such as HTML5.

Going native - Taking desktop applications to mobile devices

  4. 4. tanzer.com CHOOSING FUNCTIONALITY What your customers will need to achieve on a mobile device
  5. 5. Desktop Software What is it good for? Users are comfortable with long hours spent creating and editing documents on their desktop computers. Each user has most likely set up their system exactly how they prefer, making interaction as comfortable for them as possible. Usage • Creating & editing documents • Interacting with multiple systems Attributes • Keyboard & mouse driven • Large screens • Powerful CPU & video card • Lots of storage • Multiple windows
  6. 6. Apps on Tablets How are they used? Tablet devices are more powerful then ever, and with the BYOD trend, workers across many sectors are adopting them for daily tasks. Users on tablets are prone to short attention spans and expect fewer steps to achieve their goals. Usage • Reviewing documents • Light system interaction Attributes • Touch driven • Mid-size, high quality screens • Fast CPU & GPU • Challenges with power consumption • Single window
  7. 7. Apps on Smartphones Interactions on the go The days of only using mobile phones for phone calls are gone. In some countries, web usage on smartphones has surpassed that on desktop PCs. Users on smartphones expect to be able to perform small tasks quickly, and applications often have to be aware of each other (camera, social media). Usage • Sending short messages • Completing small tasks Attributes • Touch & button driven • Small screens • CPU & GPU • Challenges with power consumption • Single window
  8. 8. tanzer.com The desktop version of Evernote is feature- rich. Users are expected to create, edit & organise notes and notebooks The iPad version has fewer features than the desktop version. Users are expected to create and edit notes, but not organise. Evernote on mobile phones is aimed towards basic use. Panes have their own view with simple functionality Case Study Evernote

  27. 27. tanzer.com Case Study Infrastructure • Made assumptions about user behaviour • Mapped out cloud architecture • Finger in the air estimates (never correct!) • Realised we need the following experts to help us take our desktop application to mobile devices: • Solutions architect for cloud infrastructure • Web Applications Developer for ensuring correct behaviour • User account database architect to ensure binders are shared with the right people Cloud Scenario
  28. 28. tanzer.com Finally Conclusion If your goal is long term success, invest early in: • Determining your target users’ pain points • Focus on mobilising the portions of your application that solve those pain points • Interview users in order to develop user scenarios to ensure you’ve not forgotten anything • Create prototypes and run usability tests • Don’t focus on short-term gain at the cost of bringing the best product to market
