Mock Presentation

Description

Like the mock design review and the mock demo, the mock presentation is an informal, mandatory event designed to better prepare you for your Final Presentation. These sessions are run by staff and students from the Department of Communication, who are experts in teaching professional communication skills. In this session, you are only given five minutes to present a few slides on one major component of your project. Your presentation should include at least one block diagram, one graph/plot, and some math. You will also have the opportunity to see several other mock presentations. You will be given feedback based on the organization of the presentation, delivery and your ability to present as a team (so all members must speak).

Requirements and Grading

The mock presentation is meant to be a small subset of your final presentation. It is recommended that you choose some aspect of your project (like a major block from your block diagram) and present the design, requirements, and verification for that block. In order to get relevant feedback on your presentation skills, your mock presentation should also have an introduction (where the project is introduced) and a conclusion that wraps everything up. You will receive feedback on both your delivery, the format of your slides, and the organization of your presentation.

Your slides should generally include:

  1. Title slide: Names, group #, title.
  2. Introduction slide: What is the project?
  3. Objective slide: What problem does this solve?
  4. Design Slides: A few slides on design, requirements and verification (should include block diagram, math, graphs, figures, tables).
  5. Conclusion: Wrap things up, future work.

Mock presentation is graded credit/no credit based on attendance and apparent effort; showing up completely unprepared will earn no credit. An example mock presentation can be found here: example mock presentation

Submission and Deadlines

Sign-up is handled through PACE. Time slots are 1 hour long, and multiple groups will share a time slot. This will give you an opportunity to give and receive feedback from your peers. You will be required to stay until all groups have presented and received feedback.

## Problem:

A fountain show on campus can make students feel more relaxed after class. However, some fountain shows only have monotonous, stiff, and single actions. Besides, they cannot automatically generate action and light effects. Compared with large fountain shows, small and medium-sized fountain shows have the advantage of time and space. In most cases, a large fountain show only has preloaded music which cannot be decided by audiences. Large fountain shows also require people to design the action and light effects for each music, which takes lots of time and effort. Compared with the large fountain show, our small fountain show will be more energy-efficient and environmentally friendly. During the COVID-19 pandemic, large fountain shows might result in large crowds gathering, but a small fountain show can reduce the risk of infection.

## Solution Overview:

Our fountain show would be built at a pool on the sourthwest of the main lake on campus. By manually programing, the fountain show could realize changing lighting effects and movements. Besides, our fountain show could also identify the music which was imported into our system, and automatically generate the lighting effects and movements with the music. If time permits, we will strengthen the human-computer interaction of our product. To be specific, people could scan the QR code or use our online system to choose the music they want, so that they can enjoy the fountain show at any time.

## Solution Components:

### Control Subsystem:

- Music colleccting and analyzing subsystem: Computer that can import music signals and analyze them.

- Converting subsystem: After music signal is analyzed, we need computer to convert useful signals into digital signals. Digital signals will be used to control LEDs and other mechanical subsystems.

### Mechanical Subsystem:

- Pump Subsystem: Water pump that can pump water from the lake. Valves will be used to control water’s flow rate of each nozzle.

- Lighting Subsystem: LEDs are needed to light our fountains. They are controlled by microprocessor on PCB. Their brightness and color can be changed with music.

- Motor Subsystem: Two motors are needed for each fountain nozzle to control the movements. The motors are controlled by microprocessor on PCB.

### Power subsystem:

- The pump is drived by DC power (12V 20~30A). PCB and computer will be drived by USB (5V 1A). Full module power supply with 12V and 5V output is needed.

## Criterion for Success:

- If it can successfully identify a piece of music and convert it to electrical signals that we need in controlling LED’s lighting and nozzle’s moving.

- If the whole system can work stably for a long time and whether it is safe to use without electric leakage or other problems.

- If music playing, fountain movements and LED lights are synchronized.

- If the fountain system is neat and whether the fountain performance is ornamental enough.
