台灣的有聲號誌

Posted by H. Lee on November 29, 2009

我還記得數月前回台灣有看到下面新聞說的有聲號誌。當初就很好奇視障者要怎麼從聲音來判斷哪個方向是綠燈可以走 (不只是三種聲音的讓我好奇,之前看到一種聲音的就一直很好奇了…) ,因此看到之後就在馬路上研究了起來。當時的地點是在某所視障學校旁邊,我和我爸邊等紅綠燈就邊討論。旁邊一個人聽到我們的對話,就告訴我們他是視障學校的老師,其實他的學生平常都是聽車子的聲音來判斷是否該過馬路,各種有聲號誌反而會干擾視障者對於路況的判斷…

我覺得最基本的問題在於,聲音的方向性很小。要用聲音來指出紅綠燈的狀態很簡單,但是要用來指出哪個方向可以走就很困難。

剛剛看到這則新聞之後又想了一下要怎麼做。也許可以利用 Audio Spotlight 的技術來指出方向 (這個方法已經出來好幾年了) 。簡單的說, Audio Spotlight 可以讓只在某個區域的人聽到聲音。而做法如下:

大區域方式: 讓聲音只出現在目前是綠燈的斑馬線區域,這樣視障者就可以知道自己走在安全的區域。

小區域方式: 產生一面聲音牆,擋住目前是紅燈的斑馬線入口。

不過不論哪種方式,非視障者也會聽到就是了。 (但干擾會比現有的系統小。)

話說回來,如果現在是打算要給每個視障者發一個小裝置,那應該有更多種解決方法才對。未來也許可以用手機來做些什麼?

(當然以上方式都得考慮成本就是了…)

有人有什麼好建議願意分享或 off-line 討論嗎?

有聲號誌亂叫 視障者險撞車 【聯合晚報╱記者陳珮琦/台北報導】 2009.11.30 02:52 pm

為提升無障礙環境空間品質,台北市政府斥資4千多萬元在市區122個路口設置有聲號誌,以布穀聲、鳥聲和蟋蟀聲三種時相讓視障者得以分辨,但北市議員陳玉梅抽查發現故障率竟佔一半以上,且視障者抱怨常搞不清楚三種聲響的差別,反而幫倒忙,甚至還差點被車撞。

對此,台北市交通工程管制工程處交通規畫科長紀勝源表示,目前這套有聲號誌換裝工程尚未驗收,仍在測試階段,廠商已計畫加裝擴音喇叭部分,設計成「白天響、晚上不響」,避免夜間擾亂安寧。市府也將就視障者的意見,進行改善。

台北市政府自97年9月起,斥資4225萬元在全市各行政區內的122個路口,陸續換裝這套北市府自行研發的新式有聲號誌,並同步發給全市5813位視障者一個自動感應器,可於5 公尺距離內感應啟動有聲號誌,協助視障者安全地過馬路。

「害我和我太太差點被車撞!」雙連視障關懷基金會董事長楊錦鐘說,有聲號誌裝設後,他常常搞不清楚三種聲響的差別,不然就是音量小得聽不到,有天晚上他和同樣也是視障的太太外出,依照有聲號誌聲響的指示過馬路時,反而差點被車撞上。

不僅如此,楊錦鐘說,台北市發給他們一個自動感應器,如果到時候台北縣或是其他縣市也跟進設置路口有聲號誌,「那我不就變成多槍俠,身上要帶好幾個感應器。」而且有時感應器的電池沒電,沒響也不知道,徒增危險。

The Minds of Billy Milligan

Posted by H. Lee on November 27, 2009

“The Minds of Billy Milligan” by Daniel Keyes is a book I finished few weeks ago. It’s a story about a person called Billy Milligan with dissociative identity disorder (DID). The Chinese and Japanese versions of this book were quite popular both in Taiwan and Japan, but unfortunately the English version hasn’t been published due to Milligan’s ongoing lawsuit against the State of Ohio.

I knew this book when I was a college student, but I didn’t get the chance to read it until now. Reading this book made me wonder how little I know about brains and minds again.

I guess, in some sense, we all have “multiple personalities” but unlike DID persons, all our personalities share the same memory. For example, from this book Billy has 24 personalities and at beginning each of his personality had his/her own memory so each personality didn’t know other personalities exist. They just felt that sometimes they lost some time and memory and awoke in unexplained locations and situations. Later one “smarter” personality tried to figure out what happened and even found a way to organize all other personalities. Actually, the original personality (Billy) was put into sleep for several years when he tried to attempt suicide and stopped by other personalities.

Not just memory, each Billy’s personality has his/her own names, (mental) ages, interests, skills, hand writing, accent, and sex. One of them is even color-blindness and one of them is a lesbian. (I am kinda surprised that some of above things are related to our mentality.) They use their own time learning, so one of them became an expert in picking locks and escaping, one of them became a weapon expert and know how to control his adrenalin to generate powerful strength, one of them was really into science and liked doing research, and etc. Naturally, different personalities play different roles. For example, one is responsible for protecting the body (and all other personalities) from dangers, one is responsible for organizing all personalities. However, most Billy’s personalities are kids. I guess it’s because kids are easier to survive from trauma.

Currently, the causes of DID haven’t been fully identified, but high percentage of DID persons report child abuse, especially sexual abuse. Researchers conjecture that when a person is harmed by someone he/she truests, this person splits off his/her awareness and memory to mentally survive from the events. Later the memory becomes a separate personality. This happens repeatedly and multiple personalities develop. The book describes some doctors tried to help Billy to merge his multiple personalities. He did merge some of his personalities for a while but later he was sent to a different hospital and his personalities separated again possibly because of stress. The book ends here and the latest (final) result was not written in the book. I am not sure what’s the state-of-art treatments for DID persons but I believe it takes time. Curiously, it seems that some of Billy’s skills were weakened when his personalities were merged.

In addition to “The Minds of Billy Milligan”, recently I also read some books by Oliver Sacks. He is a neurologist and also the author of several books of case studies of people with neurological disorders. I enjoy his books very much and recommend to people who are interested in psychology.

After reading those books, I get more interests and curious about subconscious. I wonder how it influences us, and maybe I should read more starting from the books by Carl Jung.

Death makes you focus your priorities

Posted by H. Lee on November 21, 2009

Dr. House: It’s a basic truth of the human condition that everybody lies. The only variable is about what. The weird thing about telling someone they’re dying is it tends to focus their priorities. You find out what matters to them. What they’re willing to die for. What they’re willing to lie for. <Three Stories, House, M.D.>

Today I met an American. He lived in Taiwan for around a year before (Hualien is one of his favorite place in the world now) and can speak good Mandarin. Someone asked him why he wanted to live in Taiwan and learn Mandarin. He said he once felt illness and went to see a doctor. That doctor told him that he needed to have big brain surgery. He was shocked, but later luckily his doctor told him that his diagnosis was wrong. This event made him realize that he might not have the chance to fulfill his dream, which is to live in a foreign country and learn a different language. That’s why he made his mind to act soon.

Actually, few days ago, I met someone who just recovered from a big brain surgery. He had a benign tumor removed from his brain and after the surgery he permanently lost his taste for food. He told me that his dangerous surgery made he have a new perspective on life.

Few days ago, a friend of mine told me something he read from a book. The book says if you want to plan your life, you can start it by imaging your funeral. Imaging in your funeral what you want other people to say about you?

Google v.s. Microsoft

Posted by H. Lee on November 19, 2009

Google: I am relative young. You already have large territories on both Desktop/Notebook OS and Microsoft Office. So, I don’t attack your main territories. Instead, I attack the areas you are not that good at. For document software, I have Google Docs that focus on online collaboration. For OS, I target mobile phones first. It’s easier to have new and better software (service) in these areas and if we do a good job, more and more users will use them. The trend is on our side because more and more people get online and mobile. When the time comes, I start the invasion on your territories. For OS, we will have the version for Notebooks then maybe Desktops/Notebooks. For Google Docs, I can have new versions for companies. If I fail to take your territories, it’s OK because I already have my territories now. If I make it, I can hurt you.

Microsoft: I am rich. From my point of view, you are only good at Search Engine. I will attack your foundation directly by using lots of my resources. If I make it, I can hurt you deeply. If not, I get almost nothing, but I will try it again.

Google data only, VoIP driven device?

Posted by H. Lee on November 18, 2009

Gphone rumor again!

It says Google might have a cell phone that is “data only, VoIP driven device”. What does it mean? It means you can access Internet using your cell phone, and you can also make/receive calls via VoIP. To call or get calls, you need software on your cell phone such as Skype, Gizmo, or most probably the software that supports Google Voice. The benefit for users is that it might only cost $20~$30 per month, but I guess the call quality might be (slightly) worse.

Actually, I have been looking for this kind of solution for around 2 years. I will prefer a plan with pre-pay Voice and monthly-pay unlimited data. So, if Google releases this phone, it might fit my need.

Some imges make you think…

Posted by H. Lee on November 16, 2009

(well, no real images here, just descriptions)

A powerful and successful man wears just an underpants and walks in front…

A supermodel gets sick and lies down on a hospital bed…

A similar-age friend in a coffin…

Enjoy my time alone at home

Posted by H. Lee on November 14, 2009

During the past few weeks (or months) I have been busy running here and there during the whole weekend. Today I attended an event at Mountain View from morning to afternoon. After the event, I decided to do some grocery shopping and go home to cook a bit.

Actually, I never thought that I would miss the time I can just cook in my kitchen and enjoy the dinner on my own. But tonight I did feel relax and really appreciate the opportunities that I could be alone at home… :)

Richard Powers’ 6 hand Reel

Posted by H. Lee on November 6, 2009

We learned this fun dance tonight. It’s Scotch Reel. The sequence was constructed by Richard Powers. It’s often done to the Ghostbusters theme song, that I think is a very interesting match.

(Many dancers in this video are beginners, and they learned the whole dance from 7 basic steps in an hour.)

Dancing Love Birds

Posted by H. Lee on October 30, 2009

Social Dance 一年多,常會見到某些人,久了雖然不一定認識,但就變成熟面孔。在這麼多人之中,有一對情侶特別引我注目。他們的年紀大約是高中或是大學生,男的帥女生很漂亮,感覺非常登對。更重要的是,他們的舞技都不錯。每次看他們跳舞,我都有一種在看兩隻恩愛的小鳥飛舞嬉戲的感覺。他們的肢體語言與眼神讓我覺得充滿感情又帶點俏皮,並非深情款款但就讓你覺得他們是對可愛的戀人。加上他們的舞步氣質又優雅,非常賞心悅目。

我一開始注意到這對情侶是看到他們跳 Congress of Vienna 。據說這原本就是情侶跳的舞。不知是否是因為某種傳統,這支舞每次在 FNW 都會放兩次。 (不確定是否因為某些人可能有一個以上的愛人,畢竟現在你可以跟任何人跳這支舞。) 今晚他們在跳這支舞的時候,男的手上拿著一個氣球,然後女生就一直要去拿那顆氣球。有時候女生搶到了,又換成男生試著要把氣球搶回來。當然在過程中他們還是保持著優雅的華爾茲舞步,所以看起來就像是兩人繞著飛舞一般。非常可愛,也非常甜蜜。
