[personal UX reflection: holistic approach] an enlightening thought about product development at a civil-defense training

story: At a civil-defense training today esp. on fire prevention, a thought came up that designers and engineers need to take a great consideration even in selecting materials for doors knobs because the knobs can become a guiding signal whether the room behind is on fire or not by transmitting heat on the material. By making it with perhaps copper or heat-transferable material, the careful selection of material may save lives for people who are trying to escape in a panic room caused by fire. 

lesson: all people involved with product development (e..g product managers, designers, engineers) need to approach the product's design with a holistic and inclusive perspective to think beyond its directly intended function; though a decision made for a material choice for the product may seem small, the decision can save lives. 

[personal UX/UI review] information design for Google Knowledge Panel's "You will get updates on Google Now"

• feature: Knowledge Panel feature on Google Search product
• issue: not clear usage of words by "updates"
• recommendation: if the "updates" is referring to Google+ posts, how about 
• (1) using "Google Plus post updates" instead of "updates" to send a clear message so that users can not just be assured by where (i.e. Google Now card) the updates will be displayed and what kind of information (i.e. Google+ posts) will be updated
• (2) removing the line under "Get updates about Kevin Kelly" and somehow put the get updates and "Recent posts" modules together so that information hierarchy is clear to understand
• (3) inserting a new line between "Recent posts" and Books module because they are two different entity
• lesson: in UI design, to avoid confusion sometimes it is important to specify what and where users get when they press a clickable link or button

[tool recommendation] cloud-based, annotate-able and share-able screenshot software: Monosnap

 The best screenshot tool ever for your desktop (both PC and Mac), iPhone, and iPad to annotate and share seamlessly. 

The best part is that this tool is FREE even for the usage of its cloud system! 
Because of this tool's user-friendliness, functionality and perhaps most importantly simplicity, I just couldn't close my mouth after install the program on my PC and iPhone and use it. 

Thanks to whoever designed and developed this tool. Highly recommended!

[Personal UX/UI review] unnecessary interaction to see iOS's Messages's time stamp

• app: Messages (iOS's default text message app)
• issue: the time stamp appears when swiped to the left although the space doesn't change after swiping interaction
• recommendation: just display the time stamps so users don't even need to swipe to see when each message is sent or received

I.       Android design guideline [Chansuk Yang, Developer Relations]

1.       Message

1)      Basic advice

①  targetSDK>19 (meaning use the most recent)

②  change support package level to support minimum Android OS level

2)      What’s new in KitKat

①  Home menu button: use app launcher icon as home menu button

②  Visual design: when design, comply with people’s mental model so users don’t need to learn something new

③  Two gestures: for zooming in and out, double touch or double touch drag

④  Full screen mode: lean back mode (touching the screen in any way will bring navigation and notification bar back into place.), immersive mode (swiping down from the top or up from the bottom will bring notification bar or navigation bar respectively)

3)      Android design pattern

①  Action Bar: app icon, view control, action buttons, action overflow

A       Suggestion: Android doesn’t recommend customized Action Bar

②  Up and back difference

A       Up: higher category

B       Back: previous page or closing a pop-up window

③  App structure

A       Tab: fixed and scrollable tabs; needs to be located at the top of the screen; needs to support swiping

B       Navigation Drawer: system bar needs to stay

④  Dialogue and Toast principle

A       Principle

l  How much impact will the action bring to users? E.g. purchase brings a great impact

l  Does it allow users miss-click?

l  Can the result of the action returnable?

l  Sufficient user feedback to users? E.g. Facebook’s like button

B       Example: closing an app-> taking too much time-> consider using Dialogue window

⑤  Notification: utilize expand and contract option

4)      Responsive design

①  Need to support tablet

②  Use DP (density-independent pixels) (e.g. 200 dp)

③  Resource qualifier- provide different size icons

2.       Takeaway

1)      targetSDK>19 (meaning use the most recent)

2)      Home menu button: use app launcher icon as home menu button

II.      Chrome WebView Essentials [Alex Danilo, Developer Advocate]

1.       Message

1)      What does this mean?

①  New capabilities:

A       indexedDB: important technology to store data (e.g. games)

B       Web Sockets: push data back and forth client and server

C       requestAnimationFrame: synchronize animation on screen (not wasting time compared to JavaScript)

D       SVG filters and Effecs: e.g. convolution blurs

E       H/W accelerated rendering (e.g. <canvas>)

②  Debugging Features: Analyzing web traffic, monetizing

③  Hybrid applications: Use native component, interfacing JavaScript to native

④  Compatibility mode: Use targetSDK>19

⑤  Multi-threading and thread blocking

⑥  Custom URL Handling: URLs must conform to RFC 3986

⑦  Viewport Changes

⑧  Styling Changes

⑨  Sizes are in CSS pixels instead of screen pixels

2)     Best practices

①  Set SDK version to 19: <uses-sdk android:targetSdkVersion=”19”.>

②  Enable hardware acceleration: <application android:hardwareAccelerated=”true” ..>

③  Enable Debugging: WebView.setWebContentsDebuggingEnabled(true);

3)      The Future: Web RTC (real-time communication; P2P communication; e.g. Google Hangouts is coming
