Incorporating Feedback to Improve App Prototypes
- 2. Agenda Topics • Database • App testing and incorporating feedback Activities • Check-in (20 mins.) • Database (20 mins.) • Presenting prototype for testing – ( 60 mins.) • Sharing prototype for feedback (20 mins.) • Wrap-up – (10 mins.)
- 3. Check-in: paper prototype • Team members share paper prototype of their app idea • Explain the key functionalities and features 2
- 4. Databases • Organized collection of data • Intended to organize, store, and retrieve large amounts of data easily Examples: • iTunes is a database for all your music • Google has a database of websites which is used for Google Search • Facebook is a database of people 3
- 5. Databases in App Inventor • Reference to the colored Dots tutorial from last session: http://tinyurl.com/k2qahq7 • If participants want to save data after the application is closed they must use a database Two types of databases: • TinyDB stores data directly on the phone and will only be used by that phone (hand-set) • TinyWebDB stores data on a web database that can be shared among phones 4
- 6. Data • Key – label for what’s inside • Value – data that’s inside We use the Key to look up the Value in the database Example: Phone Book (a database of contact information) Key = name Value = phone number 5
- 7. Database for App? 6 How can you use a database for your App?
- 8. Incorporating feedback: Making your App better • Feedback from potential customers will… Tell you if your solution (app) to a problem is accurate Suggest improvements that can be made in the design of the app Suggest other features to add (either now or in the future) 7
- 9. Activity: Usability Testing • Test your paper prototype Ideas for testing paper prototype: Create a short video walking the audience through the features of the paper prototype Create a PowerPoint presentation listing each screen on a slide Share the video/presentation with your survey respondents, friends and colleagues, WeTech team (wetech@iie.org) 8
- 10. Activity: Usability Testing • Create video/PowerPoint presentations • Decide on how will the prototype be circulated for feedback • Create timeline for collecting and incorporating feedback 9
- 11. Collecting Feedback on Prototype 10 Questions Notes Suggested Changes Is there anything that is unclear or confusing in the user-interface? Would your user prefer the app look or behave differently? Which features of your app interface and usability are of highest value to your target market? Are there any missing buttons or other content from your app? Did the user’s expectations differ from the intended functionality of the app?
- 12. Task List • Collect feedback for prototype • Each team member can be assigned responsibility for updating different prototype screens based on feedback received 11
- 13. 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
Editor's Notes
- Objectives: • Students will learn how to use a database • At this point, students should have: o Gathered results from at least 20 surveys to understand their market o Completed their paper prototype • After this lesson, students will better understand the importance of giving and incorporating others’ feedback into their paper prototype.This lesson is great for students’ professional development. Beyond the Technovation Challenge, a goal of this lesson is to be able to incorporate feedback and criticism, which will help them in their school life, college career, and professional career. By being able to handle constructive criticism and remove an emotional reaction to other’s feedback, students will be able to grow.
- Last week when we participants looked at ColoredDotsthey used TinyDB to build their app. This week they will go further into databases .
- For our purposes, data has two attributes – a key that defines it and a value that is the data. The key is unique. The value doesn'thave to be unique – more than one person in this room go to the same schoolYou cannot find out the key from the value, you can only find out the value from the key. Analogy to the key to your house
- List some ways a database can potentially be used. Have the team members share ideas on what features/functionalities of their app would require a database.
- Incorporating feedback goes along with the topics we’ve discussed in the past: lean thinking, usability testing, customer development and the prototype lifecycle. Basically, feedback from others makes the app better. Everyone comes at life with a slightly different perspective. Participants would want their app to appeal to as many different people as it can.
- Before the participants create their app on the app inventor platform, they can test the prototype and make necessary changes by testing their paper prototype.

- Participants can use the above form to collect feedback and record changes that would like to make for their app design.
