1
00:00:01,000 --> 00:00:05,000
伴我同行：
計算機與傷殘人士

2
00:00:15,000 --> 00:00:20,220
我很喜歡計算機，我希望學習更多有關它的知識

3
00:00:20,220 --> 00:00:26,150
因為我想修讀計算機學

4
00:00:26,150 --> 00:00:32,530

這正是我將來想擁有的職業。

5
00:00:32,530 --> 00:00:36,200
我唯一需要的幫忙就是把計算機打開

6
00:00:36,200 --> 00:00:39,500
然後把耳機戴上

7
00:00:39,500 --> 00:00:43,560
除此之外，我都可自己操作

8
00:00:43,567 --> 00:00:45,400
這真是一項成就

9
00:00:45,400 --> 00:00:48,140
你會為此驕傲：當你真的可以

10
00:00:48,140 --> 00:00:52,050
向前邁進，而想幹點什麼也不用有求於人

11
00:00:52,050 --> 00:00:53,850
你懂罷

12
00:00:53,850 --> 00:00:56,110
這就像說“這都是我自己做的，做得好”

13
00:00:56,970 --> 00:00:59,090
除了對科技感興趣外，

14
00:00:59,090 --> 00:01:02,420
這些人士的另一共通點就是有行動障碍

15
00:01:02,420 --> 00:01:04,180
但每個人又有點不同

16
00:01:04,180 --> 00:01:06,080
連他們用電腦的方法也各有不同

17
00:01:06,080 --> 00:01:10,050
其實很難找到一刀切的

18
00:01:10,050 --> 00:01:11,880
技術是所有人都適用的

19
00:01:11,880 --> 00:01:15,350
每個有殘障，行動不健全的人

20
00:01:15,350 --> 00:01:20,070
都需要有針對他們獨特需要的設計

21
00:01:20,070 --> 00:01:24,730
最终由他們決定設計是否管用

22
00:01:24,730 --> 00:01:28,120
“這技術適合我嗎？抑或有別的東西

23
00:01:28,120 --> 00:01:30,960
更適合我？

24
00:01:30,960 --> 00:01:33,270
個別人士的行動障礙可能

25
00:01:33,270 --> 00:01:36,220
並不容易讓人察覺，而一些人有類似的

26
00:01:36,220 --> 00:01:40,540
身體狀況卻有不同類型的適應性技術。

27
00:01:40,540 --> 00:01:42,260
要點是與用計算機的人保持緊密合作，

28
00:01:42,270 --> 00:01:46,200
以找出最佳的配套。

29
00:01:46,200 --> 00:01:52,950
要注意個別用家的需要

30
00:01:52,950 --> 00:01:57,870
透過實地觀察

31
00:01:57,870 --> 00:02:00,160
他或她用該技術

32
00:02:00,160 --> 00:02:06,560
並且與用家溝通

33
00:02:07,264 --> 00:02:09,389
我們會展示適應性技術的範例

34
00:02:09,389 --> 00:02:13,620
行動障礙人士用過認為有效

35
00:02:13,620 --> 00:02:16,470
首先是如何跑到計算機跟前

36
00:02:19,800 --> 00:02:24,160
不能跑到計算機跟前，就不能用機

37
00:02:24,160 --> 00:02:26,550
所以要懂得如何進入大廈裡

38
00:02:26,550 --> 00:02:30,740
經過通道，然後舒適地坐在工作台前

39
00:02:30,740 --> 00:02:32,600
工作和學校的計算機應放在

40
00:02:32,610 --> 00:02:36,200
可以讓輪椅人士進入的位置

41
00:02:36,200 --> 00:02:40,990
能夠進入建築物，實驗室，教室這些地方

42
00:02:40,990 --> 00:02:46,450
非常重要，因為這些技術


43
00:02:46,450 --> 00:02:50,010
不管有多好，假如不能夠

44
00:02:50,010 --> 00:02:54,750
讓殘障人士觸得及的，就完全沒用了

45
00:02:54,750 --> 00:02:59,200
就是說，有樓梯就要有坡道;

46
00:02:59,200 --> 00:03:02,460
大廈有梯級，就要有電梯

47
00:03:02,460 --> 00:03:05,460
計算機間的走廊要有足夠空間

48
00:03:05,460 --> 00:03:07,900
或是有足夠空間的走廊。

49
00:03:08,960 --> 00:03:11,460
家具也要注意。

50
00:03:11,460 --> 00:03:13,160
鍵盤，電腦屏幕，和桌子高度的

51
00:03:13,170 --> 00:03:16,760
能調整靈活性是很重要的

52
00:03:16,760 --> 00:03:19,500
可調節的桌子可以上下調較

53
00:03:19,500 --> 00:03:22,750
讓顯示器高度適中。

54
00:03:22,750 --> 00:03:25,440
鍵盤托盤可以上下移動，或傾斜，

55
00:03:25,440 --> 00:03:27,320
使輸入更容易。

56
00:03:31,860 --> 00:03:34,440
一些有行動障礙的人士沒有

57
00:03:34,440 --> 00:03:38,820
使用標準鍵盤的靈活性或活動能力。

58
00:03:38,820 --> 00:03:42,400
幸好坊間有大量的替代品。

59
00:03:42,400 --> 00:03:46,420
其中一些已經裝置在現在常用的操作系統中。

60
00:03:46,420 --> 00:03:48,840
事實上，操作系統中內置一些基本功能

61
00:03:48,840 --> 00:03:52,790
是很重要的。其實可以做一些非常

62
00:03:52,790 --> 00:03:56,420
簡單的事，透過使用控制面板，


63
00:03:56,420 --> 00:04:00,980
輔助功能選項控制面板，便能基本操作

64
00:04:00,980 --> 00:04:03,680
鍵盤和操作系統。

65
00:04:03,690 --> 00:04:06,330
例如，使用單一手指

66
00:04:06,330 --> 00:04:09,190
或嘴棒的人就不能同時鍵入兩個鍵

67
00:04:09,190 --> 00:04:12,850
例如“控制”鍵和其它鍵。

68
00:04:12,850 --> 00:04:16,890
有一個方法可以讓這些鍵順序輸入。

69
00:04:17,400 --> 00:04:19,880
另一個設置可消除持續按鍵

70
00:04:19,890 --> 00:04:22,860
過久的重複按鍵。

71
00:04:22,860 --> 00:04:25,960
同時，在文字處理軟件和

72
00:04:25,960 --> 00:04:29,420
其它應用的常見功能如自動更正

73
00:04:29,420 --> 00:04:32,320
可讓用戶以簡列字

74
00:04:32,320 --> 00:04:33,940
來縮寫長字甚或句子。

75
00:04:33,950 --> 00:04:36,270
設置縮寫後，

76
00:04:36,270 --> 00:04:39,880
打字便更快更準。

77
00:04:39,880 --> 00:04:42,280
物理支援也要考慮。

78
00:04:42,280 --> 00:04:44,360
例如鍵盤

79
00:04:44,370 --> 00:04:50,060
鍵盤上有一個網格，

80
00:04:50,060 --> 00:04:55,320
在每個鍵都有孔，能防止

81
00:04:55,320 --> 00:05:01,080
錯誤輸入

82
00:05:01,080 --> 00:05:05,120
如活動不受控制時。

83
00:05:06,600 --> 00:05:08,240
對於活動能力有限的人，

84
00:05:08,250 --> 00:05:10,990
迷你鍵盤可能有用。

85
00:05:10,990 --> 00:05:13,790
左／右手鍵盤

86
00:05:13,790 --> 00:05:15,840
對只能單手操作者也蠻有用

87
00:05:15,840 --> 00:05:19,300
對於有良好活動能力但靈活性差的人

88
00:05:19,300 --> 00:05:21,940
可提供有特大鍵的鍵盤

89
00:05:25,550 --> 00:05:28,060
對於不能啟動鍵盤的人士

90
00:05:28,060 --> 00:05:30,300
虛擬鍵盤可能更有用

91
00:05:30,300 --> 00:05:32,230
它設在電腦顯示屏上

92
00:05:32,230 --> 00:05:33,920
就像鍵盤上的圖片。

93
00:05:33,920 --> 00:05:37,050
可以使用鼠標，軌跡球

94
00:05:37,050 --> 00:05:39,110
或替代指點系統激活鍵。

95
00:05:39,110 --> 00:05:42,100
一些虛擬鍵盤可以包括諸如

96
00:05:42,100 --> 00:05:45,660
替代鍵佈局或字預測軟件的特徵。

97
00:05:51,740 --> 00:05:54,560
詞預測程序幫助人們正確輸入


98
00:05:54,560 --> 00:05:55,740
和更快。

99
00:05:55,750 --> 00:05:59,780
該程序基於已經鍵入的單詞提示

100
00:05:59,780 --> 00:06:01,720
用戶可能的單詞選擇列表。

101
00:06:01,740 --> 00:06:05,080
透過用戶使用和工作常用詞彙，

102
00:06:05,080 --> 00:06:08,015
一些程序收集新詞以提供預測。

103
00:06:08,015 --> 00:06:12,475
我輸入了一封信。譬如說，我輸入了一個“T”，

104
00:06:12,480 --> 00:06:15,340
以“T”開頭的五個字就會彈出

105
00:06:15,350 --> 00:06:17,970
我最常用的那些供我使用。

106
00:06:17,970 --> 00:06:21,340
它們會彈出來，我點擊，然後就打印了。

107
00:06:25,920 --> 00:06:28,620
圖片用戶界面無處不在

108
00:06:28,620 --> 00:06:31,470
你需要有一些指示設備

109
00:06:31,470 --> 00:06:33,880
在電腦獲取這些材料

110
00:06:33,880 --> 00:06:36,990
圖標，點擊，指向所有這些東西。

111
00:06:36,990 --> 00:06:39,110
所以你需要
使用鼠標

112
00:06:39,110 --> 00:06:41,320
或找到替代方案
來使用鼠標。

113
00:06:42,800 --> 00:06:44,840
軌跡球
是一個好開始。

114
00:06:44,850 --> 00:06:48,870
軌跡球的控制面是
比鼠標更容易操作。

115
00:06:48,870 --> 00:06:53,560


116
00:06:53,560 --> 00:06:55,770


117
00:06:55,770 --> 00:06:58,300


118
00:06:58,300 --> 00:07:01,800


119
00:07:01,800 --> 00:07:05,730


120
00:07:05,730 --> 00:07:08,740


121
00:07:08,740 --> 00:07:11,910


122
00:07:11,910 --> 00:07:14,120


123
00:07:14,120 --> 00:07:16,780


124
00:07:16,780 --> 00:07:17,970


125
00:07:17,970 --> 00:07:20,540


126
00:07:20,540 --> 00:07:22,360


127
00:07:22,360 --> 00:07:24,220


128
00:07:24,220 --> 00:07:30,720


129
00:07:30,720 --> 00:07:34,760


130
00:07:42,520 --> 00:07:43,980


131
00:07:43,990 --> 00:07:46,860


132
00:07:46,860 --> 00:07:48,000


133
00:07:48,000 --> 00:07:50,220


134
00:07:50,220 --> 00:07:51,960


135
00:07:51,960 --> 00:07:54,900


136
00:07:54,910 --> 00:07:59,550


137
00:07:59,550 --> 00:08:01,250


138
00:08:01,250 --> 00:08:07,050


139
00:08:07,050 --> 00:08:10,180


140
00:08:10,180 --> 00:08:14,140


141
00:08:14,140 --> 00:08:17,290


142
00:08:17,290 --> 00:08:20,800


143
00:08:20,800 --> 00:08:23,590


144
00:08:23,590 --> 00:08:28,280


145
00:08:28,280 --> 00:08:30,230


146
00:08:30,230 --> 00:08:33,289


147
00:08:33,289 --> 00:08:35,090


148
00:08:35,090 --> 00:08:37,840


149
00:08:37,840 --> 00:08:39,690


150
00:08:39,690 --> 00:08:41,890


151
00:08:41,890 --> 00:08:44,520


152
00:08:44,520 --> 00:08:47,210


153
00:08:47,210 --> 00:08:49,590


154
00:08:49,590 --> 00:08:52,960


155
00:08:52,960 --> 00:08:55,040


156
00:08:55,040 --> 00:08:56,800


157
00:08:56,800 --> 00:08:59,770


158
00:08:59,770 --> 00:09:03,230


159
00:09:03,230 --> 00:09:07,710


160
00:09:07,710 --> 00:09:11,140


161
00:09:11,140 --> 00:09:14,650


162
00:09:14,650 --> 00:09:17,510


163
00:09:17,510 --> 00:09:19,380


164
00:09:19,380 --> 00:09:22,370


165
00:09:22,370 --> 00:09:24,840


166
00:09:24,840 --> 00:09:26,600


167
00:09:26,600 --> 00:09:29,250


168
00:09:29,250 --> 00:09:32,550


169
00:09:32,550 --> 00:09:35,320


170
00:09:35,320 --> 00:09:38,120


171
00:09:38,120 --> 00:09:42,600


172
00:09:42,600 --> 00:09:46,340


173
00:09:46,340 --> 00:09:49,500


174
00:09:49,500 --> 00:09:52,260


175
00:09:55,980 --> 00:09:57,820


176
00:09:57,827 --> 00:09:59,410


177
00:09:59,410 --> 00:10:02,630


178
00:10:02,630 --> 00:10:05,770


179
00:10:05,770 --> 00:10:08,160


180
00:10:08,160 --> 00:10:13,550


181
00:10:13,550 --> 00:10:15,390


182
00:10:15,390 --> 00:10:18,950


183
00:10:18,950 --> 00:10:20,800


184
00:10:20,800 --> 00:10:23,460


185
00:10:23,460 --> 00:10:24,950


186
00:10:24,950 --> 00:10:27,340


187
00:10:27,340 --> 00:10:30,580


188
00:10:32,160 --> 00:10:34,880


189
00:10:34,880 --> 00:10:36,940


190
00:10:36,940 --> 00:10:39,050


191
00:10:39,050 --> 00:10:42,420


192
00:10:42,420 --> 00:10:45,460


193
00:10:45,470 --> 00:10:48,710


194
00:10:48,710 --> 00:10:51,380


195
00:10:51,380 --> 00:10:54,200


196
00:10:57,820 --> 00:10:58,700


197
00:10:58,700 --> 00:11:00,440


198
00:11:00,450 --> 00:11:02,780


199
00:11:02,780 --> 00:11:04,890


200
00:11:04,890 --> 00:11:07,320


201
