對(duì)于 MEMS 技術(shù)在智能手機(jī)應(yīng)用的快速發(fā)展，“室內(nèi)導(dǎo)航”功能其實(shí)也扮演著一部份的推動(dòng)力量，但它卻一直未能展現(xiàn)最佳效果，而這項(xiàng)功能對(duì)于手機(jī)用戶來(lái)說(shuō)實(shí)際上也不是這么的需要。 在日前于慕尼黑舉行的“歐洲MEMS產(chǎn)業(yè)高峰會(huì)議”(MEMS Executive Congress Europe)上，Nokia Lumia Technology音頻硬件資深經(jīng)理Teemu Ramo表示，在未來(lái)的一些手機(jī)設(shè)計(jì)中，壓力傳感器以及其他傳感器可能會(huì)被省略掉。 Teemu Ramo表示：“以往的作法是把每樣?xùn)|西都塞進(jìn)去。但目前我們看到的趨勢(shì)是‘少即是多’(less is more)。例如室內(nèi)導(dǎo)航并未如預(yù)期地成功。因此，在手機(jī)設(shè)計(jì)時(shí)就不必加入壓力傳感器了。我們必須問(wèn)的是：某種特定傳感器的附加價(jià)值是什么？如此來(lái)看，氣體傳感器就是多余的了?！? 壓力傳感器可用于區(qū)別購(gòu)物商場(chǎng)的不同樓層，但問(wèn)題是：這對(duì)于誰(shuí)更有利？ 用戶是相當(dāng)精明的，而且知道壓力傳感器存在的原因之一是讓他們可被定位──但其實(shí)他們并不喜歡這項(xiàng)功能。再者，一些無(wú)法有效發(fā)揮作用的室內(nèi)導(dǎo)航系統(tǒng)還會(huì)對(duì)手機(jī)制造商品牌帶來(lái)負(fù)面影響。 同時(shí)，Ramo指出，在組件數(shù)、成本、能耗以及有效執(zhí)行主要功能方面，也都會(huì)帶來(lái)業(yè)務(wù)壓力。 Ramo 指出，即將來(lái)臨的手機(jī)設(shè)計(jì)趨勢(shì)之一是更著重于用戶實(shí)際所需要的功能，而非故意用一些令人驚奇的新技術(shù)做為噱頭吸引早期采用者。他表示，用戶的基本要求其實(shí) 都會(huì)先經(jīng)過(guò)電信業(yè)者加以過(guò)濾，但卻可能還要求Nokia以及其他手機(jī)業(yè)者持續(xù)在手機(jī)中加入越來(lái)越多的MEMS以取悅App開(kāi)發(fā)商。 此外，他說(shuō)，無(wú)線電信標(biāo)(radio beacon)已成為新的研究焦點(diǎn)了，因?yàn)楹轿煌扑阆到y(tǒng)并不十分準(zhǔn)確，經(jīng)常發(fā)生用戶實(shí)際上在購(gòu)物商場(chǎng)中卻顯示人還在外面的錯(cuò)誤情況。即使是室內(nèi)導(dǎo)航系統(tǒng)能發(fā)揮效用，對(duì)于電信業(yè)者以及其他產(chǎn)品與服務(wù)供應(yīng)商的好處也比對(duì)于手機(jī)用戶來(lái)得多。 Ramo表示，當(dāng)手機(jī)制造商專注于用戶真正想要以及有用的功能時(shí)，移動(dòng)電話領(lǐng)域?qū)?huì)進(jìn)入一個(gè)新時(shí)代。例如，三星在發(fā)布 Galaxy S5 時(shí)即轉(zhuǎn)為強(qiáng)調(diào)少即是多的策略。 他還表示，雖然智能手機(jī)早期采用者可能是一些想“嘗鮮”的技術(shù)愛(ài)好者，但下一代智能手機(jī)采用者將會(huì)更著重于評(píng)估產(chǎn)品的基本功能是否有效發(fā)揮。支持原創(chuàng)，鄙視抄襲，請(qǐng)?jiān)L問(wèn)《國(guó)際電子商情》網(wǎng)站www.zgwwsyw.com 本文授權(quán)編譯自EE Times，版權(quán)所有，謝絕轉(zhuǎn)載 編譯：Susan Hong 參考英文原文：Has Indoor Navigation Lost Its Way?，by Peter Clarke

{pagination} Has Indoor Navigation Lost Its Way? Peter Clarke Indoor navigation, which has been a driver for at least some MEMS developments in smartphones, doesn't work well and is not really needed by phone users. As such, pressure sensors, along with other sensors, could be omitted from some handsets in the future, according to Teemu Ramo, senior manager of audio hardware for Nokia Lumia Technology. Speaking on a panel at the MEMS Executive Congress Europe, held in Munich, Germany on March 11, Ramo said: It used to be that we chucked everything in. We are seeing a move to 'less is more.' For example indoor navigation has not panned out as planned. So the pressure sensor may get dropped from the mobile phone. We have to ask: What is the added value for any given sensor, so the air pressure sensor may go. The pressure sensor is there to distinguish between floors of multi-level shopping mall, but the question is: for whose benefit? Users are savvy and know that one reason it is there is so that they can be pitched at -- and they don't much like it. Also an indoor navigation system that doesn't work well merely serves as a persistent, negative advert for the phone maker's brand. Meanwhile, there is business pressure to component count, cost, and energy consumption and do primary functions well, Ramo indicated. It is part of what could be a coming trend to focus on what smartphone users actually want rather than gimmicks intended to wow technophile early adopters, according to Ramo. He did qualify this by saying that user requirements do get filtered through the mobile phone service operator channel, which may yet dictate that Nokia and other phone companies continue to throw more and more MEMS into their handsets to please apps developers. When asked at the end of the panel about indoor navigation he said that radio beacons had become the focus for research because the dead-reckoning systems were not very accurate and often showed users being outside a mall when they were inside. Even if indoor navigation systems worked they would be of more use to mobile phone service and other product and service vendors than they are to the users of the mobile phone. "Human beings do good sensor fusion and tend to know where they are," said Yannick Levy, vice president of corportate business development at consumer electronics company Parrot SA, who was also on the panel with Ramo. "I might become a fan [of indoor navigation systems] if I saw one that worked properly," Ramo told the audience. When asked about this on the fringe of the meeting Ramo said that he felt that the mobile phone sector might be entering a new era where makers focus on what users want and use. "Samsung with the Galaxy S5 has said less is more," Ramo said. He also said that while the first tier of smartphone adopters have been technophiles that wanted to try everything, the next generation of smartphone adopters will value the basic functions being done well.
