Chrome "Super Sync Sports": HTML5 game makes kids happy


Chrome Super Sync Sports: Sync your mobile to your computer to Run! Cycle! Swim! Choose from 50 athletes and get racing! Play solo or challenge friends.

Based on technology integration on HTML5, CSS3, WebSockets, and Google App Engine, this game should be the best demo for recent Mobile Web applications.
  • All client/server services are WebKit compatible, so that you just connect the URL and play the game.
  • In a game pool, at most four players (client-sides) just user their smartphones or tablets to connect the URL (http://http://chrome.com/supersyncsports/#/en-US/) and input the code for the selected game. Chrome, Safari, or other WebKit-based browser (maybe) are workable to play the game.
  • The Mobile Web tech also supports good experiences on gestures defined in three sports.
  • Although the user interaction is not as good as native apps or online games (install modules on client desktops), it proves Mobile Web is approaching to the UX (User eXperience) of native apps.
  • The most successful part is the "clipart & visual art" jobs, 50 avatars with animations on loss or win are very cute and really attract kids to enjoy and to be exciting.
It's a little pity that the services is not stable on connections. Sometimes, one or two players may disconnect, and the game may be disconnected so that all players must reload and reconnect.

When I watched the demo video, I totally guess right technologies applied in the games and mobile devices. The only one miss is "why not use QR codes?" Input 5-char code is easy. However, if one creates the game, the page can present "4 QR codes" so that each player takes a photo on one QR code to get one of four players. In this way, it will be more interesting.

假性近視 & 散瞳劑 Questions?




散瞳驗光 (cycloplegic refraction) 的功能是放鬆「長期過度緊用眼」,導致「眼睛睫狀肌 (ciliary muscle) 疲勞」,以獲得真正的眼屈光狀態,檢驗出正確視力。以藥物使睫狀肌麻痺,失去調節以檢驗出正確視力,尤其是在檢驗幼童是否有「假性近視 (pseudo myopia)」,就會先點「短效散瞳劑」,以排除假性近視的因素,檢驗正確度數。長時間眼睛的休息也可以有同樣的效果,但是不知該休息多久?

Youth vision loss or vision instability (measured vision while clearly, while it is not clear), suspected pseudomyopia should cycloplegic refraction be excluded. Once the dilation of regulation disappeared, pseudomyopia restored.
使用散瞳劑可以放鬆睫狀肌到正常視力,但是長時間使用後,除了可能的副作用外,若不點散瞳劑之後,睫狀肌是否又會回到近視的狀態,或是更嚴重?也找不到文獻說明清楚。所以,到底點或不點,有定論嗎?

The company, Polytron Technologies Inc., comes from Taoyuan, Taiwan. It leads worldwide manufacturer of electronic and optical vision glass. Although it's merely a prototype now, but Polytron promises the transparent cell phone will appear at the end of this year. Let's look and see.
  • Electric current is carried through transparent wires. (no-wired LED)
  • A dual-sided multi-touch display in front and back.
The prototype has yet to feature any software or operating system. Which OS is better? Android or iOS? Any ideas of Apps integrate AR (Augmented Reality) into the transparent cell phone? Or integration of Apps with the see-thru Google Glass?

Read the company's website. It's interesting. The tech. was used in air crafts, shows (rear projects), CSI ... Ghirardelli (in SFO http://picasaweb.google.com/lh/photo/oxHk2ZUxMqKbXAK7ULK2GQ) also uses its product in the glass of showcase.

Use your browser as TEXT Editor


If you suddenly want to write something without text editor on your device, try to use WebKit-based browsers: Chrome, Firefox, and Safari.

In the URL line, input:

  • "data:text/html, <html contenteditable>", then you can edit texts on the page presentation area.
However, the above command make the text area as HTML default, that is copying html strings will be pasted as HTML format. If you want a "pure text" (plain text) editor, use the command.
  • data:text/html, <textarea></textarea>
The input area is too small! Don't forget write CSS style as you are a good web programmer.
  • data:text/html, <textarea style='height:90%;width:90%;margin:auto'></textarea>
Now, enjoy your "Programmer-Style" text editor.

I am glad to be a programmer!

NOTE: the edited text can not be saved!
