Technovation challenge workplan for week 4

  1. 1. User Centered Design Lesson 4
  2. 2. Agenda Topics • Survey results • Multiple screen and logic components for the App • User-centered Design Activities • Check-in for Survey Results – (15 mins.) • Colored Dots tutorial – (30 mins.) • Introduction to User-centered design – (10 mins.) • Usability testing (20 mins.) • Creating a Paper Prototype (30 mins.) • Wrap-up – (10 mins.)
  3. 3. Check in • Share interesting results or trends from your surveys • Is there a good size market for your app? • Are you looking to make any changes on your app idea based on the survey ideas?
  4. 4. Colored Dots This tutorial shows how to create apps that have multiple screens. In App Inventor, you can have a screen and can open a second screen. Later, the second screen can return to the initial screen that opened it. You can have as many screens as you like, but each screen closes by returning to the screen that opened it. The screens can share information by passing and returning values when they open and close. The screens also share the same TinyDB data, which they can use to store and share values. http://tinyurl.com/k2qahq7
  5. 5. Colored Dots This tutorial is an introduction to:  Multiple Screens  TinyDB  Brush Picker
  6. 6. Multiple Screens • • • You can add screens in the designer and use the screen transitions in blocks editor to decide which screen to go to next  For Example: if they push the menu button go to the menu screen Screen 1 will always be the screen the app starts on – probably best to make it a welcome screen You have to “package for the phone” to test moving between screens
  7. 7. Tiny DB • • Besides opening screens and returning values, the different screens in a multiple screen app can communicate through TinyDB. To do this, give every screen its individual TinyDB component. ColoredDots uses TinyDB to let you name the colors you create and save them to later use. The saving and naming will be done in Brush_Picker, as shown in the blocks later
  8. 8. Brush Picker The main job of Brush_Picker is to create a color from the redgreen-blue values entered in the text boxes and provide that color to Screen1. One thing the Brush_Picker needs to check is that it's using good values for colors and dot size. Each of the red, green, blue values should be a number between 0 and 255.
  9. 9. Putting it all together
  10. 10. What is User-Centered Design? Designing things with the user in mind. You are not always the user.
  11. 11. Designing with the user in mind? • • • Crash dummies – moving from only men to women and children! http://tinyurl.com/kb34cec Crash dummies are a perfect example of not designing with the user in mind. When they were first created, they were all shaped like adult men. As a result, women and children where killed by automobile accidents at a higher rate than men. Now, there are female dummies, male dummies, and children dummies. Now designers are even considering making crash dummies bulkier to accommodate the increasing average weight in the United States. These dummy designers are now creating dummies with the user in mind.

  13. 13. What is User Interface? • User Interface: link between the user person and the technology • User Interface Design: designing technology that makes sense to user – “intuitive” design User Interface: Buttons User Interface: Touch Screen
  14. 14. Prototyping Lifecycle Have users test the prototype and ask them questions about their experience with it. Incorporate feedback. What does it need to do? What is the goal? Who is your user? What do they expect? What do they want? Prototyping. Create samples. Source: Debra Lauterbach
  15. 15. Usability Testing • Watch video on testing usability: http://www.youtube.com/watch?v=6TbyXq3XHSc • Ask participants to shares thoughts about creating prototypes based on the video
  16. 16. Activity: Usability testing of competitor apps • Investigate 2 or 3 apps that are similar in function to yours or that have the same target customer • Search on App Store for iPhone and Google Play for Android apps • Browse the apps and discuss the following:  What does it do well?  What could it do better?  Make notes about the features/interface  Color scheme, size/layout of buttons, readability, etc. Optional: If participants have their workbooks ask them to fill in the chart on page 11 of the workbook
  17. 17. So you have competition… So what? • You can make a better product! • Plastic bags can cover you from the rain…but aren’t you glad people invented raincoats?
  18. 18. Activity: Prototype Plan (20 min.) • • • • Skills and tools you need Components and skills Research tutorials and videos Divide up the work: each team member will program at least one screen.
  19. 19. Plan for completing a prototype Features Resources Timeframe
  20. 20. Activity: Create a paper prototype
  21. 21. Task List • Finish the paper prototype and bring to next session • Also, continue to gather survey responses to make sure that the team better understands the market of their app
  22. 22. Wrap-Up • Share a photo of your session with WeTech at wetech@iie.org • Encourage participants to join WeTech Technovation Facebook group to stay connected with the larger community http://tinyurl.com/mmzjwed
