亲身体验苹果全新智能手表和iPhone 6

    表盘的右侧有两个按钮——一个被称为“数码表冠”的拨盘，拨盘的操作很像人们过去用来给手表上发条的表冠。不过，对于苹果智能手表而言，拨盘是用来导航屏幕菜单的。将拨盘向左或右旋转，可以将主屏幕上显示的应用放大或缩小。同时，按下拨盘下面的按钮，将会显示好友和家人的简要列表。

    苹果宣称，这款功能会在那些希望快速找到通讯录的人中大受欢迎。比如，苹果公司运营高级副总裁杰夫•威廉姆斯（Jeff Williams）使用手表测量心跳，然后将心跳数据发送给他的一个朋友——比如当时正在台上的苹果互联网软件和服务高级副总裁埃迪•库埃。

    在现实世界中，我从未见过用这种方式来分享脉搏跟踪数据的情况，但是，如果我想在出去慢跑的时候向朋友口授一个文本，这个功能就十分有用了。苹果还花费大量的精力制作了两款新的健康应用程序——一款用于跟踪用户每天的活动，另一款用于跟踪特定的活动（比如5公里跑）——但是我未能测试这两款应用程序。

    On the right side of the watch face are two buttons — a dial called the “digital crown,” which operates a lot like the crowns people used to wind up their old watches. Only here, that dial helps to navigate menus on the screen. Screwing the dial left and right zooms in and out on the apps featured on the main screen. Meanwhile, pressing a button below the digital crown brings up a brief list of favorite friends and family members.

    Apple argues this feature will become popular with people seeking a shortcut to quickly their contact list. As an example, Apple SVP of Operations Jeff Williams measured his heartbeat with a watch and sent it to one of his buddies, in this case, Apple SVP of Internet Software and Services Eddy Cue, who was onstage.

    In the real world, I can’t see pulse-tracking being shared this way at all, but I can see this becoming useful if I want to dictate a text to a friend while out jogging. Apple also made a big deal over two new fitness apps — one for tracking my movements everyday, the other for tracking specific activities like a 5-mile run — but I wasn’t able to test those out.
