????Jawbone最初揚名立萬靠的是高品質、高回頭率無線設備。首先它的藍牙耳機系列大獲成功；隨后，在去年末，其便攜音箱又迅速風靡世界，成為大家必不可少的配件。

????現在，這家位于舊金山的公司又推出了新產品——UP手環。這是一款漂亮的防水腕帶，內置加速器，和蘋果（Apple）iPhone的加速器頗為相似。Jawbone并不打算發布一款音響設備，這家獲得風投支持的公司如今瞄準了另一迅速增長的市場——個人健康配件。位于德克薩斯奧斯丁的市場分析公司First Research表示，雖然現在對UP手環進行市場分析為時尚早，但整個美國健身設備市場的年銷售額約為30億美元。

????UP手環是如何工作的呢？用戶可以用它記錄自己的日常生活：走了多長距離的路？速度如何？消耗了多少熱量、睡眠了幾個小時——甚至還能記錄睡眠質量。只要將UP手環中隱藏的耳機插頭插入iPhone的耳機孔內（位于充電孔邊），手環上的所有數據就會同步到iPhone的應用程序中，該程序能分析數據并生成鮮明的彩色圖。（Jawbone希望用戶能每天同步兩到三次。）用戶可以通過應用程序拍攝用餐照片，記錄每次用餐后的感受，來掌握每天的飲食狀況。

????Jawbone希望用戶能對自己的身體狀況有整體認識，倡導健康生活方式。每次同步后，UP手環都會變得更加“聰明”，例如：用戶只需自定義時間范圍，手環即可在用戶睡眠時挑選出最佳時刻，通過震動將其喚醒。11月6日，UP手環將在美國率先上市，定價為99美元，屆時Jawbone官方網站會提供銷售，遍布美國的蘋果、百思買（Best Buy）、塔吉特（Target）和美國電話電報公司（AT&T）零售店也會參與銷售；隨后的11月17日，UP手環將在英國上市。

????Jawbone聯合創始人兼首席執行官侯賽因?拉赫曼認為，UP手環吸取了公司各方面的精華——換句話說，這是一個戴在手腕上的高精尖飾品。拉赫曼稱：“我們在這一領域的設計理念是進行一些從內到外的全面創新，然后將這些創新融合在一起，使其具備高度便攜性、可用性，使用戶夢寐以求，同時還能與用戶手頭最智能的便攜設備（此處指iPhone——譯注）兼容。”

????UP手環還融入了大量社交功能。它能不斷更新數據，顯示其它UP手環用戶的使用狀況。用戶能加入不同群組，參與到其它用戶或每日功績（DailyFeats）、24小時健身（24 Hour Fitness）、更健康一代聯盟（Alliance for a Healthier Generation）等健康組織發起的個人或團體競賽中。這樣的競賽可能是與朋友協作，在特定時間完成步行10萬步的步行；也可能是一日三餐都吃健康食品。這些功能使UP手環和耐克（Nike）旗下的Nike+以及Fitbit等產品頗為相似，后者也是一款記錄用戶活動的設備。

????Jawbone made a name for itself cranking out high-quality, head-turning wireless devices: first with a successful line of Bluetooth headsets, then with a portable speaker that quickly became a must-have gadget late last year.

????Now, the San Francisco-based company is branching out. Its new UP is a slick, water-resistant wristband with a built-in accelerometer, much like Apple's (AAPL) iPhone. Instead of making another audio device, the venture-backed startup is pushing itself into the rapidly emerging market for personal health gadgets. Though estimates for UP's niche aren't available, according to the Austin, Texas-based market analysis firm First Research, the overall fitness equipment market is worth some $3 billion in sales annually in the U.S.

????How does the device work? It lets users track their daily routines: how much and how fast they walk, calories burned, how many hours slept -- and even the quality of that sleep. Plug the hidden headphone jack into an iPhone's audio jack-in between charges and all that data is synced with an app that analyzes and displays it in brightly colored graphs. (Jawbone expects users to do that two or three times a day.) The app also lets users track how much they eat by letting them snap photos of meals and document how they feel after each meal.

????The idea is to give users a holistic view of their health, encouraging them to make healthy changes. UP gets a little "smarter" with each sync, vibrating and waking users at the best time in their sleep cycles within a user-assigned time frame, for instance. The device will be available on Jawbone's web site, as well as Apple, Best Buy (BBY), Target (TGT) and AT&T (T) locations in the U.S. on November 6 for $99; a UK launch is set for November 17.

????Jawbone co-founder and CEO Hosain Rahman says the idea combines areas of strength for the company -- namely high-tech gadgets that can be worn. "A lot of what we were envisioning with this space is, let's take some interesting innovation both internally and externally, and pull it together in a package that's highly wearable, highly desirable, easily usable and pair it with the smartest device in your pocket," he says.

????There's also a big social element. A news feed of data from the device streams updates of what other UP users are up to. Users can join teams, participate in individual or group challenges created by other users or health organizations like DailyFeats, 24 Hour Fitness or Alliance for a Healthier Generation. An example might include collectively walking 100,000 steps with friends by a certain day and time or eating three healthy meals a day. That puts the device in a similar category as Nike's (NKE) Nike+ products and Fitbit, a device that tracks users' movements.
