Mock Presentation

Description

Similar to the Design Doc Check and the Mock Demo, the Mock Presentation is an informal, mandatory event designed to better prepare you for your Final Presentation. In these sessions, you will present a few of your slides (about 10-15 minutes), and get feedback from the course staff as well as a few invited Department of Communication TAs. You will also be able to see a few of your peers' Mock Presentations, as there are up to 3 teams per time slot.

Requirements and Grading

The Mock Presentation is meant to be an opportunity for you to get feedback on a subset of your final presentation. It is recommended that you choose some aspect of your project, and present the design, results, and conclusions from that aspect. In order to get relevant feedback on your presentation skills, your Mock Presentation should also have an introduction and conclusion. You will receive feedback on 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.

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:

Being an ECE student means that there is a high chance we are gonna sit in front of a computer for the majority of the day, especially during COVID times. This situation may lead to neck and lower back issues due to a long time of sedentary lifestyle. Therefore, it would be beneficial for us to get up and stretch for a while every now and then. However, exercising for a bit may distract us from working or studying and it might take some time to refocus. To control mice using our arm movements or hand gestures would be a way to enable us to get up and work at the same time. It is similar to the movie Iron Man when Tony Stark is working but without the hologram.

# Solution Overview:

The device would have a wrist band portion that acts as the tracker of the mouse pointer (implemented by accelerometer and perhaps optical sensors). A set of 3 finger cots with gyroscope or accelerometer are attached to the wrist band. These sensors as a whole would send data to a black box device (connected to the computer by USB) via bluetooth. The box would contain circuits to compute these translational/rotational data to imitate a mouse or trackpad movements with possible custom operation. Alternatively, we could have the wristband connected to a PC by bluetooth. In this case, a device driver on the OS is needed for the project to work.

# Solution Components:

Sensors (finger cots and wrist band):

1. 3-axis accelerometer attached to the wrist band portion of the device to collect translational movement (for mouse cursor tracking)

2. gyroscope attached to 3 finger cots portion to collect angular motion when user bend their fingers in different angles (for different clicking/zoom-in/etc operations)

3. (optional) optical sensors to help with accuracy if the accelerometer is not accurate enough. We could have infrared emitters set up around the screen and optical sensors on the wristband to help pinpoint cursor location.

4. (optional) flex sensors could also be used for finger cots to perform clicks in case the gyroscope proves to be inaccurate.

Power:

Lithium-ion battery with USB charging

Transmitter component:

1. A microcontroller to pre-process the data received from the 4 sensors. It can sort of integrate and synchronize the data before transmitting it.

2. A bluetooth chip that transmits the data to either the blackbox or the PC directly.

Receiver component:

1. Plan A: A box plugged into USB-A on PC. It has a bluetooth chip to receive data from the wristband, and a microcontroller to process the data into USB human interface device signals.

2. Plan B: the wristband is directly connected to the PC and we develop a device driver on the PC to process the data.

# Criterion for Success:

1. Basic Functionalities supported (left click, right click, scroll, cursor movement)

2. Advanced Functionalities supported(zoom in/out, custom operations eg. volume control)

3. Performance (accuracy & response time)

4. Physical qualities (easy to wear, durable, and battery life)
