PowerPoint pitfalls

Concerns about PowerPoint

• Information overload

• Oversimplification of complex ideas

• Minimizes presenter’s role

Concerns about PowerPoint(cont)• Form overtaking content

• Slides that are difficult to read, difficult tounderstand or distracting

Edward Tufte“PowerPoint is Evil”

• “With so little information per slide,many, many slides are needed. ....Wheninformation is stacked in time, it is difficultto understand context and evaluaterelationships.”

William Germano“The Scholarly Lecture: How to Stand and Deliver”

• “If you put your bulleted points up onslides, your audience will look at the slides,not at you. You’ll be teaching them thatWhat You Have to Say Can BeSummarized in a Few Words. Can it?”

Edward Tufte“PowerPoint is Evil”

• “Audience boredom is usually a contentfailure, not a decoration failure.”

Avoid pitfalls: Strategy 1

• Put yourself in the place of your audience


• Decide what is important/pertinent

• Remove everything else

Images

• Acquiring– Scanning, cameras, web, photo cd

• image size, bit depth

• Manipulating / Optimizing– PhotoShop, PowerPoint

• sizing, cropping, compressing

Bitmaps

• Images from digital cameras, scanners,photo CDs and web pages are calledbitmaps

• These graphic files are all made up of aset of dots

• The dots are called pixels on visualdisplays

Pixels

• The word Pixel is derived from the phrasepicture element.

• When working with images on computerscreens or projection devices pixels arethe unit of measure

• "Dots Per Inch" DPI or "Lines Per Inch"LPI are irrelevant on screens or projectors

Resolution

• More pixels = higher quality (moreinformation)

• More pixels = bigger files

• For any given device there is amaximum number of pixels it candisplay

• The number of pixels = a device'sresolution.

Typical Screen Resolutions

4 megapixel digitalcamera

2400 x 1600

2 megapixel digitalcamera

1792 x 1200

1.3 megapixel digitalcamera

SXGA1280 x 960

Typical laptop orprojector

XGA1024 x 768

typical 17” MonitorSVGA800 x 600

typical 15" MonitorVGA640 x 480

A typical scenario

Too many pixels?

• 2000 pixels can’t fit on a 1024 pixel widedisplay

• Extra pixels are either cropped or lost!

• Reducing an image by 50% throws awayapprox 75% of the information

50%

75%

What to do…

• Create digital images that contain only asmany pixels as you can or want to display

• A full screen image should be about 1000pixels wide

• A half screen image about 500 pixels

• A full screen vertical image should beabout 750 pixels tall

1024 x 768

Digital Cameras

• Choose the 1024x768 setting if available

• Use the camera’s best “quality”

• Manipulate using graphics software– PhotoShop, MS Photo Editor

• Save as .jpg and insert into PowerPoint

• Retain an original copy!

Full size JPG 50k 50% TIF 1,010k

Camera Image

Create digital images that containonly as many pixels as you can orwant to display

Scanning

Scanning

• Determine the final image size in pixels– 1000 for full screen width, 500 for half screen,

etc.

• Measure the original in inches

• Number of pixels divided by number ofinches = scanner setting (ppi)

• Set the scanner to the setting nearest tothe calculated ppi

Original is 3.75 inches wideTarget 700 pixels wide700 ÷ 3.75 = 187ppiScan at 200ppi200 X 3.75 = 750 pixels

From Dell support:

Extended Desktop functionality was introduced in Windows 98 SE (SecondEdition) and was fully planned for Windows 2000. As Windows 2000 wasdeveloped, Microsoft decided to de-feature multi-monitor support for single-adapter /dual-controller video solutions as part of the Operating System. Single-adapter /dual-controller video is often found in portable computers, including DellInspiron and Latitude systems with ATI-based video solutions, including the ATIMobility M/M1/P, Mobility 128 and Mobility M4. This type of video solution usesa single video adapter with multiple video controllers emulated in driver software,rather than a single adapter for each video controller (as commonly found indesktop systems).

Although Windows 98 SE and Me (Millennium Edition) do support extendeddesktop with a single-adapter /dual-controller video solution, this functionality isnot natively supported in Windows 2000.
