他们当时还是信息技术专业的学生。
01:29
when they were students学生们
in information信息 technology技术.
21
77913
2832
01:33
They noticed注意到 that quite相当 often经常,
22
81425
2668
他们注意到,很多情况下,
01:36
the midwife助产士 was not able能够
to hear any heart rate
23
84117
3084
当那里的助产士
尝试用角状听诊器去听的时候,
01:39
when trying to listen to it
through通过 this horn喇叭.
24
87225
2688
其实根本听不到任何心跳的声音。
01:42
So they invented发明 their own拥有
fetal heart rate monitor监控.
25
90665
4537
因此,他们发明了
自己的一套胎儿心跳监视器。
01:48
They adapted适应 the horn喇叭
and connected连接的 it to a smartphone手机.
26
96156
4599
他们改造了角状听诊器,
并将它和智能手机相连接。
01:52

5237
我有一个同事名叫
苏德什·思沃苏(Sudesh Sivarasu),
他发明了智能手套来帮助麻风病人。
03:01
for people who have suffered遭遇 from leprosy麻风.
46
169090
2166
03:03
Even though虽然 their disease疾病
may可能 have been cured治愈,
47
171799
3005
即使他们的疾病可以被治愈,
但是麻风对神经的伤害会导致
03:06
the resulting造成 nerve神经 damage损伤
will have left many许多 of them
48
174828
3156
03:10
without a sense of touch触摸 in their hands.
49
178008
2538
他们手部的触觉丧失。
这会使他们很容易受伤。
03:12
This puts看跌期权 them at risk风险 of injury.
50
180570
2058
03:16
The glove手套 has sensors传感器

SudeshSudesh invented发明 this glove手套
after observing观察 former前任的 leprosy麻风 patients耐心
55
196032
4689
苏德什在仔细观察了之前的
麻风病人每天要做的事情,
03:32
as they carried携带的 out
their day-to-day日复一日 activities活动,
56
200745
2946
而且在得知这些病人
03:35
and he learned学到了 about the risks风险
and the hazards危害 in their environment环境.
57
203715
3589
时刻面临受伤的风险之后,
发明了这款手套。
03:41
Now, the inventors发明家 that I've mentioned提到
58
209774
2180
上述提到的这些发明者
03:43
integrated集成 engineering工程 with healthcare卫生保健.
59
211978
2679
结合了电子工程和健康管理的知识。
03:47
This is what biomedical生物医药 engineers工程师 do.
60
215260
2235
这也是许多生物医学
工程师做的事情。
03:50
At the University大学 of Cape Town,
61
218558
1905
在开普敦大学,
我们开设了一门名叫
“健康的创新设计”的课程。
03:52
we run a course课程 called
Health健康 Innovation革新 and Design设计.
62
220487
3157
03:55
It's taken采取 by many许多 of our graduate毕业
students学生们 in biomedical生物医药 engineering工程.
63
223668
3947
主修这门课程的是
生物医学工程的研究生。
04:00
The aim目标 of the course课程
is to introduce介绍 these students学生们
64
228106
3597
这门课程的目标是
为学生们介绍
04:03
to the philosophy哲学 of the design设计 world世界.
65
231727
2555
设计世界中的哲学。
他们鼓励学生加入一些团体,
04:06
The students学生们 are encouraged鼓励
to engage从事 with communities社区
66
234306
3021
寻找与健康相关问题的解决方案。
04:09
as they search搜索 for solutions解决方案
to health-related健康相关 problems问题.
67
237351
3243
04:13
One of the communities社区 that we work with
is a group of elderly老年 people
68
241055
3269
其中一个我们工作的社区是
一个开普敦的老年团体。
04:16
in Cape Town.
69
244348
1224
04:17
A recent最近 class project项目 had the task任务
of addressing解决 hearing听力 loss失利
70
245596
4140
一个最近的课程项目任务是
04:21
in these elderly老年 people.
71
249760
1450
去登记丧失听力的老人。
04:23
The students学生们, many许多 of them
being存在 engineers工程师,
72
251886
2772
这些学生,大部分是工程师,
他们很自信自己
会设计出更好的助听器。
04:26
set out believing相信 that they
would design设计 a better hearing听力 aid援助.
73
254682
4851
他们跟那些老人相处了一段时间,
04:31
They spent花费 time with the elderly老年,
74
259557
1608
与老人们的卫生保健人员
和看护人聊天。
04:33
chatted to their healthcare卫生保健 providers供应商
and their caregivers护理人员.
75
261189
3248
04:37
They soon不久 realized实现 that, actually其实,
adequate充足 hearing听力 aids艾滋病 already已经 existed存在,
76
265039
5114
他们不久就意识到,
事实上,合适的助听器早已存在,
04:42
but many许多 of the elderly老年 who needed需要 them
and had access访问 to them
77
270177
3996
但是很多需要并使用这些设备的老人,
却并不拥有这些设备。
04:46
didn't have them.
78
274197
1413
04:47
And many许多 of those who had hearing听力 aids艾滋病
79
275954
2112
并且很多有助听器的人,
却不会佩戴它们。
04:50
wouldn't不会 wear穿 them.
80
278090
1233
04:52
The students学生们 realized实现
81
280321
1990
这些学生意识到,
很多的老年人拒绝接受
他们有听力障碍的现状。
04:54
that many许多 of these elderly老年 people
were in denial否认 of their hearing听力 loss失利.
82
282335
3937
戴助听器会与耻辱联系到一起。
04:58
There's a stigma柱头 attached
to wearing穿着 a hearing听力 aid援助.
83
286296
2500
05:01
They also discovered发现 that the environment环境
in which哪一个 these elderly老年 people lived生活
84
289757
4758
他们还发现这些
老年人居住的环境,
十分不利于有听力障碍的人。
05:06
did not accommodate容纳 their hearing听力 loss失利.
85
294539
2023
05:08
For example, their homes家园
and their community社区 center中央
86
296586
3781
比如说,他们的家和社区中心
充斥着干扰他们听力的回声。
05:12
were filled填充 with echoes回声
that interfered干扰 with their hearing听力.
87
300391
3068
05:15
So instead代替 of developing发展 and designing设计
a new and better hearing听力 aid援助,
88
303999
5108
因此,这些学生把工作重心从开发
并设计出全新且更好的助听设备,
05:21
the students学生们 did an audit审计
of the environment环境,
89
309131
2683
改为在该环境中进行一项调查,
05:23
with a view视图 to improving提高 the acoustics声学.
90
311838
2399
以此制定出提高传声效果的计划。
05:27
They also devised设计 a campaign运动
to raise提高 awareness意识 of hearing听力 loss失利
91
315196
3834
他们还设计出一个活动计划,
来提高人们对于听力丧失群体的关注,
05:31
and to counter计数器 the stigma柱头
attached to wearing穿着 a hearing听力 aid援助.
92
319054
3576
从而消除戴助听器与耻辱之间的关系。
05:35
Now, this often经常 happens发生
when one pays支付 attention注意 to the user用户 --
93
323603
3384
当一个人开始关注使用者,
这种情况常常发生——
这里是指那些老年人——
05:39
in this case案件, the elderly老年 --
94
327011
1650
他们的需要和环境。
05:40
and their needs需求 and their context上下文.
95
328685
1965
05:43
One often经常 has to move移动 away
from the focus焦点 of technology技术
96
331219
2846
一个人常常不得不
离开科技的聚光灯,
纠正这个问题。
05:46
and reformulate重新制定 the problem问题.
97
334089
1838
05:48
This approach途径 to understanding理解 a problem问题
through通过 listening and engaging
98
336861
3977
去理解一个问题的方法是
去倾听并且参与它,
虽然这个方法已经是老生常谈,
05:52
is not new,
99
340862
1228
05:54
but it often经常 isn't followed其次 by engineers工程师,
100
342601
2612
但是它并不经常被那些
05:57
who are intent意图 on developing发展 technology技术.
101
345237
3110
一心想发展科技的工程师们所采用。
06:01
One of our students学生们 has a background背景
in software软件 engineering工程.
102
349704
3448
我们有一个学生
有软件工程方面的背景。
06:05
He had often经常 created创建 products制品 for clients客户
103
353176
2677
他曾经为顾客发明产品,
但那些产品顾客根本就不喜欢。
06:07
that the client客户 ultimately最终 did not like.
104
355877
2389
06:10
When a client客户 would reject拒绝 a product产品,
105
358902
2177
当有顾客想去
拒绝一件产品的时候,
他的公司经常表明的是
06:13
it was common共同 at his company公司
106
361103
1885
06:15
to proclaim宣布 that the client客户
just didn't know what they wanted.
107
363012
3708
顾客只是不知道
他们自己想要的是什么。
06:19
Having completed完成 the course课程,
the student学生 fed美联储 back to us
108
367384
3562
在完成课程学习之后,
那个学生给我们的反馈是,
06:22
that he now realized实现
that it was he who hadn't有没有 understood了解
109
370970
3198
现在他意识到
不知道顾客想要什么的
06:26
what the client客户 wanted.
110
374192
1421
是他自己。
06:28
Another另一个 student学生 gave us feedback反馈
111
376254
2573
另一个学生给我们的反馈是,
06:30
that she had learned学到了
to design设计 with empathy同情,
112
378851
2468
她曾经怀揣着同理心学设计,
06:33
as opposed反对 to designing设计 for functionality功能,
113
381343
2990
反对单纯的实用性设计,
06:36
which哪一个 is what her engineering工程
education教育 had taught her.
114
384357
2731
这是她的专业教育教给她的。
06:39
So what all of this illustrates说明 is that
we're often经常 blinded失明 to real真实 needs需求
115
387830
4132
我上述所有的举例说明了
我们在盲目追求科技过程中
忽视了真正的需求。
06:43
in our pursuit追求 of technology技术.
116
391986
1593
06:45
But we need technology技术.
117
393936
1581
但是我们需要科技。
我们需要助听器,
我们需要胎儿心跳监视器。
06:47
We need hearing听力 aids艾滋病.
We need fetal heart rate monitors显示器.
118
395541
2969
06:51
So how do we create创建 more medical device设备
success成功 stories故事 from Africa非洲?
119
399385
4783
那么我们如何去创造更多的
医疗设备在非洲成功的案例呢?
06:56
How do we create创建 more inventors发明家,
120
404967
1978
我们如何去培养出更多的发明者,
06:58
rather than relying依托 on
a few少数 exceptional优秀 individuals个人
121
406969
3247
而不是依赖于
一小部分有杰出能力的人,
07:02
who are able能够 to perceive感知 real真实 needs需求
122
410240
2108
那些有能力去感知
真正被需要的东西,
07:04
and respond响应 in ways方法 that work?
123
412372
1842
并且在他们的工作中做出对策的人?
07:06
Well, we focus焦点 on needs需求
and people and context上下文.
124
414718
3460
我们关注具体的需求、人群和环境。
07:10
"But this is obvious明显," you might威力 say,
125
418497
1832
“但这不是很明显的吗,”你可能会说,
”环境当然是很重要的因素啊。”
07:12
"Of course课程 context上下文 is important重要."
126
420353
2278
07:15
But Africa非洲 is a diverse多种 continent大陆,
127
423486
2408
但是非洲是一块多元化的陆地,
07:17
with vast广大 disparities差距 in health健康 and wealth财富
and income收入 and education教育.
128
425918
4871
在健康、财富、收入
和教育方面有很大的差异。
07:22
If we assume承担 that our engineers工程师
and inventors发明家 already已经 know enough足够
129
430813
5027
如果我们假定我们的

非洲多元化的环境特点,
07:30
to be able能够 to solve解决 the problems问题
of our different不同 communities社区
131
438474

从而有能力去解决不同社区
07:34
and our most marginalized边缘化 communities社区,
132
442339
1939
和我们最边缘化的社区问题,
07:36
then we might威力 get it wrong错误.
133
444302
1448
我们就有可能会向错误的方向发展。
07:38
But then, if we on the African非洲人 continent大陆
134
446907
2595
但是,如果我们在非洲大陆上
07:41
don't necessarily一定 know enough足够 about it,
135
449526
3272
得知了超出计划的环境信息,
07:44
then perhaps也许 anybody任何人 with the right level水平
of skill技能 and commitment承诺 could fly in,
136
452822
4130
然后也许有一定技术水平和
责任感的人都会飞到非洲,
07:48
spend some time listening and engaging
137
456976
2469
花一些时间来聆听、参与,
并在了解了足够信息之后
回到自己的国家开始为非洲打造新发明。
07:51
and fly out knowing会心 enough足够
to invent发明 for Africa非洲.
138
459469

07:55
But understanding理解 context上下文 is not about
a superficial interaction相互作用.
139
463953

但是对非洲环境的理解
并不仅限于浅层次的互动。
这是一种深度的参与,
08:00
It's about deep engagement订婚
140

and an immersion浸没 in the realities现实
and the complexities复杂性 of our context上下文.
141
470276

需要深入了解现实情况
以及环境的复杂性。
08:07
And we in Africa非洲 are already已经 immersed沉浸.
142
475877

我们早就深入了非洲的环境之中。
08:11
We already已经 have a strong强大 and rich丰富

我们早已拥有一个
强大且丰富的知识储备,
08:15
from which哪一个 to start开始 finding发现 solutions解决方案
to our own拥有 problems问题.
144

08:19
So let's not rely依靠 too much on others其他
145

所以,我们不需要过分依赖他人,
08:23
when we live生活 on a continent大陆
that is filled填充 with untapped未开发 talent天赋.
