如何做好一個簡報投影片

簡報的重點是人的現場表現還有你的口頭表達,投影片是輔助的性質,不是主角。
好的投影片可以幫助聽眾抓住你的表達重點。

簡報製作原則:


每張投影片不超過 5 個 bullet 項目

每個項目不超過 2 行, 且以 1 行為佳

抓出重點, 以簡短的文字敘述,不要造句,

每張投影片要有適合內容的標題,不應出現無標題

能用圖片, 就用圖片, 圖片效果勝過文字

項目用 bullets, 不用數字

Figure 不用 編號

附上笑話一則

記者訪問足球教練︰
「請問您認為足球運動對體育風氣的提升有哪些貢獻?」
「絕對沒有。」教練立即回答。
「絕對沒有?」吃驚的記者問︰「為什麼?」
「足球是22 個需要休息的人在場上拼命地跑,
而四萬個需要運動的人卻坐在那裡看!」

3/25 WiMAX Technology

  • WiMAX technology can provide coverage in both LOS and NLOS conditions.
  • NLOS has many implementation advantages that enable operators to deliver broadband data to a wide range of customers.
  • WiMAX technology has many advantages that allow it to provide NLOS solutions, with essential features such as OFDM technology, adaptive modulation and error correction.
  • Furthermore, WiMAX has many optional features, such as ARQ, sub-channeling, diversity, and space-time coding that will prove invaluable to operators wishing to provide quality and performance that rivals wireline technology.
  • For the first time, broadband wireless operators will be able to deploy standardized equipment with the right balance of cost and performance; choosing the appropriate set of features for their particular business model.

Homework 3-18-2006

WiMAX will indeed accomplish a multitude of consumer applications that will overshadow last mile communication links. Applications such as streaming video to PDA’s, cell phones, and portable PCs are one example. How about downloading music on demand to future versions of the ever-popular iPod or your favorite TV programs to your laptop while you are on a train speeding along at 75 miles per hour? The list goes on and on. Broadband will be a huge revenue engine for the providers who take heed and plan for the future. <full text>

Questions: Why are the wireless application mentioned above not doable by GPRS/3G, or Wi-Fi in terms of their specifications?

Papers about wireless networks applications on social network services

[DOC] Some Social Implications of Ubiquitous Wireless Networks
MA Smith - research.microsoft.com
Groups of people using these tools will gain new forms of social power, ways to organize and coordinate their interactions and exchanges just in time and just in place.

Wireless Location Privacy Protection
B Schilit, J Hong, M Gruteser - www-2.cs.cmu.edu

Location-based services are emerg-
ing as the next killer app in personal
wireless devices, but there are few safe-
guards on location privacy. In fact, the
demand for improved public safety is
pushing regulation in the opposite
direction.


PeopleNet: engineering a wireless virtual social network
M Motani, V Srinivasan, PS Nuggehalli

People often seek information by asking other people even when they have access to vast reservoirs of information such as the Internet and libraries. This is because people are great sources of unique information, especially that which is location-specific, community-specific and time-specific. Social networking is effective because this type of information is often not easily available anywhere else.


The Effects of a Wireless On-Line Community Network on Social Capital
M Mc Nally, M Bannon, J Greaney, A Hickey, M Mc

Technology has been traditionally seen to be a cause of decline in
social engagement and interaction, for example increased
television viewing is associated with lower levels in Social
Capital. However, it is now believed that on-line technology
and CMC can be used to increase social capital. Technology
can achieve this by removing the barriers of time and location,
allowing communication over distance and by allowing
asynchronous interaction.
