Wearable System

 

ABSTRACT

Current trends in medical instrumentation are consistent with society’s historical need to evolve its tools and products into more portable, mobile, and even wearable form factors. Time pieces, radios, and telephones are common examples of this trend. With advances in technology, miniaturization, and wireless communication, access to information is no longer limited to the static environment of the desktop. This paper general situation

®     Introduction: What Is Wearable System?

A product that is wearable should have wear-ability.

Wearable system^[i]—a system that includes a wearable computer combined with one or more other devices such as a bar code scanner or voice headset.

The word wearable implies the use of the human body as a support environment for the product. The human body is active; its form is diverse and changing. Wearable design that respects these dynamics results in product wearability. Existing static human anthropometric data provides a limited description of the body.

 

®     Character

1.         Portable while operational.

2.         Hands-free use.

Hand-free by HMD (Head Mounted Display).

3.         Always on / always running.

Since the wearable system is always powered while it is worn, users can use the system whenever they want.

4.         Sensors.

The system should be able to get information from the environment by the sensors such as wireless-communication, GPS, DC, microphone and so on.

5.         "Proactive".

Be able to offer information to the user initiatively, without any operations.

 

®     Requirement

1.         Autonomy: Making wearable devices autonomously perform tasks, such as the search for, delivery and collection of relevant information.

2.         Simplicity

3.         Flexibility

4.         Power saving: Power is an important consideration for wearable system designers. The energy consumption profile of a wearable computer determines how long a system will run given a battery size, or conversely, how large a battery must be to achieve a specified uptime. Batteries may contribute significantly to the overall volume and mass of the wearable system. For this reason, wearable designers want to know exactly how energy is consumed in the system, so that an accurate battery specification can be made.

 

®     Design

Well-designed mobile and wearable products can offer more portable and effective ways for people to relate to this information. However, simply shrinking down medical instrumentation from the desktop paradigm to a more portable scale only makes them into mini ones. It does not take advantage of the opportunities presented by a whole new context of use. It does not regard the human body as a context.

The design requirements for a wearable system^[ii] are a set of simultaneous constraints on electronics, software, mechanics, and usability. It is sometimes difficult to satisfy these requirements using only off-the-shelf componentry.

Design for wearable system focuses on a specific and important issue within the design space for developing wearable computing systems; wearability, the physical shape of wearables and their active relationship with the human form. In the sections that follow we have outlined several design guidelines for the creation of wearable system.

 

Guidelines for Wearable System:

1.       Placement (where on the body it should go)

2.       Form Language (defining the shape)

3.       Human Movement (consider the dynamic structure)

4.       Proxemics (human perception of space)

5.       Sizing (for body size diversity)

6.       Attachment (fixing forms to the body)

7.       Containment (considering what’s inside the form )

8.       Weight (as its spread across the human body)

9.       Accessibility (physical access to the forms )

10.   Sensory Interaction (for passive or active input)

11.   Thermal (issues of heat next to the body)

12.   Aesthetics (perceptual appropriateness )

13.   .Long-term Use (effects on the body and mind)

 

Architecture

 

Hardware

Today, wearable computing is being recognized as an interesting research and product area by a number of commercial entities, small and large. This has not always been the case, however, and as such, academic researchers have needed to "roll their own" hardware in order to obtain experimental results. Wearable hardware development at Carnegie Mellon has taken place at a number of points in the design spectrum, from "customer"-driven systems integration based on a task specification, to fully-exploratory systems designed in-house from a clean slate. This section contains information on the hardware systems deployed by the Group, as well as background material on the academic projects surrounding the machines themselves.

®     Examples

LifeWear

LifeWear is a wearable system used to create automatic diaries of one's daily life. The platform is composed of a Sharp Zaurus worn on the chest, two wireless accelerometers called MITes, a MITe receiver, a microphone, and a CF camera.

The code available here includes a web-based annotation tool used in the data labeling process, matlab code for training and testing models, and C code for collecting data and running the resulting real-time models. The C code uses the Enchantment Whiteboard and Signal systems, which are now based on the AWare Enchantment code base (GPL'd, included).

最后的一篇 臧兆伟传

      臧兆伟，音“脏照伟”，男，1984年11月12日出生。特地把读音标出，是因为他自己说他这个名字有“n种错误的读法”。某次去他妹妹家去后（仅此一次，勿误会，是去看她妹妹复习历史的，他也到我妹妹家去过一次，活活。说实在的……她妹妹的素质比我妹妹强太多了……），在附近的肯德基店我切身体会到了这一点……他一位本家把他的名字念成了传说中的“臧摇尾”。其他诸如“藏摇伟”等各奇怪组合暂且不表，更有“脏找胃”这个更恶搞的读法，请读者仔细品味前面仨字，老有米道额。臧兆伟的祖先臧洪，是三国时期极有个性，又极有义气的一个高士，我在之前的blog中已经有过描述，欢迎大家阅读。作为臧洪的66世孙，臧兆伟承祖古风，为人热诚，讲义气，那是谁都不能否认的。
      臧氏英文名Peter，就是磐石，就是彼得，就是耶酥的亲近门徒。虽然本人号称是无神论者，却流露出对禅宗佛教相当感兴趣的倾向。没关系，泛神论者就是无神论者嘛，我理解你的。喜欢永远长不大的Peter Pan，QQ昵称Eureka（我喜欢读成艾莉卡，即樱花大战3中女主角的名字，以此戏谑Peter）所以有个“绰号团”叫“Peter Zang Eureka那个潘”，也可简称“那个潘”。（那Cbb是哪个潘呢……另，我也有个绰号团叫“憎恶除八傻妞阿姨”……）给小四的妹妹娃娃同学补过课，被叫成“老师”，小四当面对老师必恭必敬，背后瞎胡闹，“当面叫老师，背后叫老p”。老p这个名字，也是俺想出来的，有“老屁”的意思，没办法，和徐潇坐过的人嘛。还有诸如叫他“脏脏”的，这个名字也不错，反正皮肤黑黑，黑黑脏脏，活活。
      臧自幼父母离异，家中亲戚不少，家族聚会一年总有一次。小时了了，初中入尹海根数学提高班，有一道水流中船行的问题，顺流逆流加船速，V1V2加V3，全班仅两人做出。初三直升高中，应女人对其言：“要有做好在直升班垫底的充分的思想准备。”事实证明，完全错误，应女人认人不明也不是一次两次的了。
      臧入高中，早晨体操站第三排我后面，除了八啦八啦八啦八啦和旁边的水货八啦外，最喜欢做的事情是捅我的腰，哈我的头颈——尤其知道我怕痒之后，更是乐此不疲，害我惨受此酷刑两年。臧的八啦八啦在八班是出了名的，上课坐第二排的我有时听得到坐倒数第二排的他在和拜五八啦——不是八啦的声音，是八啦的内容。上课的时候，八啦声着实有些讨厌，因此刘明华老师不止一次批评过臧，臧“虚心接受，屡教不改”；不过八啦也为他赢得了很多人缘，相信小卦啦，肖君啦袁轶婷啦，小四啦乐越啦，等等等等，听了臧的八啦声比喝咖啡还管用，想睡也睡不着。
      臧高一上的期中考试为班级第3，小测验偶尔失手，有过物理只考60多分，让肖君破涕为笑的莞尔小故事。但高三后，理科的优势让他和毛老师，水货，忻佳华等人脱颖而出，因而高考542分的成绩并不出人意料。在交大，臧加入了车协，成为了社长，加入了棒球社，成为了替补中的替补……至于学习成绩么……既有被“踢”出直研班的尴尬，又有考试因睡过头迟到的莫名。好在他对我说“无事不可对人言”，我也不怕把他那些坍台的事情搬上去。
      臧女人缘极佳，而且与我这种张扬赢得的女人缘不同（QQ第二行第五个表情，大家尽量砸我，活活），他得来的友谊更坚固，更“天长地久”。况且，我这种性格只能招来“女的朋友”……他么，活活……不说啦不说啦，八啦八啦八啦。臧第一位女友贾_颖_之，臧与其分手后，引起周围化学反应颇多。今日看来，我愿意仅仅把这当做一次分手而已。昔日黄山四人行，火车上四人（臧毛鱼我）牛皮乱吹，也只是男子汉之间的卧谈会而已。但是我愿意说的是，他坚信我也愿意坚信的是，他在对待朋友上，对待恋人上，没有做过任何亏心事，是真正问心无愧的。臧的现女友小孔同学，理理同学，性格腼腆，与小四、我之间曾发生过沟通的小问题——一点因性格不同而引发小误会。现在么……唉……这小俩口和那小俩口甜蜜着呢，八班话最多的三个人惟我不甜蜜着呢……
      通算臧友，与一众女人，卦、君、婷、猫等等等，又与一众男人，水货等等，关系都很好。与小狙称兄妹，并结交上外乖乖女草莓一颗。（这颗小草莓，后来又当上了傻妞GG，小四JJ的mm，其中小四当上了人家的jj最为莫名，本人坚决打倒，用时1秒）即使是小学同学孙晓雯（我的初中同学），他帮起忙来尽心尽力，绝无怨言。八班时期，替人解答数理化问题细心，耐心，这点翁翎同学最后体会——臧曾戏称：“我不用外面买书的，翁翎都替我买了。”惟一人除外。这人是谁，八班人人均知，不表。此人更是引起Peter高中为数极少的怒火——在某次测验中，即在考试过程中不停催问Peter答案——符合这位同学的一贯作风。
      臧曾与我，与人均提起：“李文俊是个值得相交一生的人。”虽然平日被其欺负异常之惨（言语上，肢体上，精神上），但此承诺之重，使我倍加珍视。缘分真是很奇怪的事情，虽然是高中同学，我和臧的友谊却是进大学后建立起的。他本是个“半绝顶聪明”的人，当年自称理科有上海市前100左右的实力（市一级理科竞赛基本上可以拿二等奖），如此重情，想来日后世俗成就未必惊人。但与人交，义气最重，臧如此待我，我怎不以心交之，以义报之！
      注：通常说来，压台的是最差的……所以这里要特地提一下……这个是Last but not least……最后写Peter决非最不重视他……

流水帐好报么?

似乎很好报
