Why Oral + Visual Presentations? Why oral + visual

presentations? You have a much wider bandwidth with visual.

It is the way it has been done since the beginning of education, but why?

Much of the material on presentation comes from Scientifically Speaking,Published by The Oceanography Society, www.tos.org/pdfs/sci_speaking.pdf

Why Oral + Visual? A scientific talk is an opportunity to both show

and tell. If done properly, it provides your audience with knowledge presented in a way that best enables them to absorb and retain it.

Interaction between speaker and audience Questions and Answers Speaker picks up body language from audience

Opportunity to meet the speaker first hand

Speaker and audience express commitment to learning just by showing up.

Preparation If your talk is not well prepared

and you do not deliver it in amanner that gains and holdsthe attention of your audience,much of the knowledge youhope to share will be lost.

Know your audience: technical level, critical level, enthusiasm level, etc. Content must fit the audience.

Keep to time -- don’t be cut off before the end by timing requirements

Practice, practice, practice! Dry runs before every presentation with critique from simulated audience if possible

Preparation It is extremely easy to be boring! A good talk has an introduction (the big picture),

a body and a conclusion. Use simple, direct, active words. Keep non-technical language straightforward and

uncomplicated. As Thoreau says “simplify, simplify” -- the

audience does not know the subject as well as you do.

Just as a machine does not contain unnecessary part, so a sentence should contain no unnecessary words.

Preparation Use equations and symbols sparingly In longer presentations summarize from time to

time to get audience “on the same page” with you. Credit material from outside sources -- journal,

website Dress: Play it safe, use your common sense, and,

remember, neat- ness always counts. If you err, it is wiser to err on the side of being slightly overdressed rather than underdressed.

Accomplished public speakers advise that rehearsals are almost as important to a good oral presentation as the actual content of the talk.

Visual Aids Visual aids are vehicles for enhancing or

facilitating the understanding of your spoken words. If they do not fulfi ll that purpose, they are misused.

Don’t present visual material unless it adds significantly to the spoken words.

Editing visual materials to achieve the most illustrative, effective presentation requires walking a fine line between too much and too little -- Back up slides can help solve this dilemma

Some Useful Guideline on Slides

All information presented visually should be brief and concise. It should be presented in the most comprehensible format and edited to minimum number of words possible.

Visual aids must be legible and clearly visible to the entire audience.

Two or three facts or information points per image are best; six are considered the absolute maximum.

Some Useful Guideline on Slides Do not load too much visual material into

a talk. Depending on the complexity of the material, use of three to six images per 10 minutes is usually optimal. More complex information takes more time to absorb, so reduce the number of visual pieces presented accordingly.

Do not read your visual aids to the audience instead of giving a talk.

Dry run any presentations on the type of equipment in the presentation room.

Design Review - Items to Include Project Summary Slide

A big picture cartoon of the project mission/concept This can include an answer to “Why are we

doing this project?”See next slide for example

Introduction of team members and their roles and specialties

Highlights of the project -- What is the cool new stuff in the project?

Wireless Networked Mini-Buoy Concept

Propulsion to maintain geolocation or maintain formation of an array

Array allows both high time & space resolution

Adaptive array sampling driven by real time data

Design Review - Items to Include Project Description

Overall description/summary of the project/design, what it is, what it does, what it might cost and why should anyone care? We suggest nice functional block diagrams, state

diagrams and photos -- examples follow What is your plan?

Functional block diagram, state diagram, photos if not presented earlier -- repeat diagrams as needed.

Major technical challenges and how you plan to attack them.

Schedule summary can be included here, but not too detailed.

Buoy Structure & Propulsion

Umbilical for Bench/Shore Test

Design Review - Items to Include Break down of the major subsystems/components of

the project Brief discussion of each major subsystem. Again, use block

diagrams, state diagrams and photos. Next slide shows example

Description of where you expect that the “work” of the project will be done, e.g.

Research Finding out what has been done relevant to your project What you need to know to do the following:

System design & development PCB design & fabrication Mechanical design & construction Control system design & implementation Software aspects

Communications & GPS antenna

Uplooking solar sensors GPS & communications

boards Propulsion thrusters Sensors (hyperspectral &

hydrophone) Power & motor control

boards CPU board Batteries Feed aperture for

downlooking hyperspectral sensor

Thrusters

Two, Maxon AMS-16, 2 W motors drive low-pitch propellers at ≈ 400 rpm through a 6.4:1 gear box. The propulsion system is designed for a maximum of 25 cm/s speed at 1.2 W per motor. A 100% drag margin is included. We plan an optical shaft encoder for motor control if we find it is needed.

Engine Nacelle & Propeller

Maxon motor with gear box, coupling, shaft & seals is contained in a machined plastic nacelle

Gear box is 6:1 to give screw rpm of about 300 to 400.

Struts attache nacelle to buoy hull

Alternative Options Considered As a part of your presentation it is often good to

show what alternatives you considered and why you choose the one you do.

Choosing the first thing that works is expedient, but it is not likely to yield a great design

Showing your audience that you use good design practice will give them confidence in your design

Design Review - Items to Include Tasks that remain to be done

A main part of your presentation this time Demonstrations if applicable

Probably not at this stage, but later yes, especially for the final design review.

One possibility is to have some video of lab experiments, existing solutions, etc.

Summary of experience What took most time; what was the hardest?

Conclusions This is a summary of the message that you want to

leave with your audience -- usually three or four main points. Probably include major challenges remaining.

Holger Schmidt’s Lab on a Chip

A new method of shining light through gas trapped in a silicon chip may point the way to simpler, more portable timekeepers, chemical sensors and test beds for communications networks that run on quantum weirdness.

• Scan for low concentrations of chemicals in factories or in areas at risk for chemical weapons attacks. • Make semiconductor laser frequencies more precise by locking them to vibrations of rubidium • Turn vibrations into precise timekeepers, which might benefit computer networks,
