Android Wear update to version 1.4 adds support for gestures, audio and more
To scroll through cards, quickly move your watch away from you, and then slowly bring it toward you. To go back a card, you reverse the speed by slowly moving the watch away from you, and quickly moving it toward you. To take the first action on a card, hold your arm in front of you. Push down and bring your arm back to the original position. The same gesture from the main watch screen, instead of from a card, will open the apps menu.
Other changes coming with the update include the ability of an Android Wear watch with a hardware speaker, to play sounds and take calls. Not all Android Wear watches pack the necessary speakers for this. Among those that do, are the LG Watch Urbane 2nd Edition, Huawei Watch, and the Asus ZenWatch2. With the update, you will be able to use your voice or touch to send WhatsApp, WeChat, Viber, Telegram, and Nextplus messages. There will be improvements to the battery life, and support for other languages like Mandarin, Cantonese, Indonesian, Polish, Dutch, and Thai.
The update should be rolling out shortly.
Thanks for the tip!
