CS474: Human Computer Interaction - Augmented Reality (100 Points)
Assignment Goals
The goals of this assignment are:- To write a program that uses augmented reality to display dynamic educational material
- To use opencv to create a dynamic image and display it as an AR overlay
Background Reading and References
Please refer to the following readings and examples offering templates to help get you started:- Modalities - Augmented Reality Activity
- Rosebrock, A. - OpenCV Augmented Reality (AR)
- Creating your own image using numpy and opencv
- Drawing Functions in OpenCV
- Tracking ArUCo Markers
The Assignment
In this assignment, you will incorporate the augmented reality program we explored in class into a user application. Specifically, you will write a program to solve one of two problems:
- Wireless hotspot locations and relative signal strengths
- A scavanger hunt / capture the flag game on campus using clues and hot/cold markers to inform the user
For your application, detect a particular marker on the screen (if you like, you can use a marker other than the default ArUCo dictionary, or overlay your information over the entire screen without a marker), and create a dynamic image to display meaningful information on the webcam overlay.
In addition to your implementation, be sure to include a LaTeX design report in academic journal format (you can use Overleaf for this purpose) that describes your initial design, rationale, stakeholder evaluation, and any subsequent revisions you made from your stakeholder input.
Submission
In your submission, please include answers to any questions asked on the assignment page in your README file. If you wrote code as part of this assignment, please describe your design, approach, and implementation in your README file as well. Finally, include answers to the following questions:- Describe what you did, how you did it, what challenges you encountered, and how you solved them.
- Please answer any questions found throughout the narrative of this assignment.
- If collaboration with a buddy was permitted, did you work with a buddy on this assignment? If so, who? If not, do you certify that this submission represents your own original work?
- Please identify any and all portions of your submission that were not originally written by you (for example, code originally written by your buddy, or anything taken or adapted from a non-classroom resource). It is always OK to use your textbook and instructor notes; however, you are certifying that any portions not designated as coming from an outside person or source are your own original work.
- Approximately how many hours it took you to finish this assignment (I will not judge you for this at all...I am simply using it to gauge if the assignments are too easy or hard)?
- Your overall impression of the assignment. Did you love it, hate it, or were you neutral? One word answers are fine, but if you have any suggestions for the future let me know.
- Any other concerns that you have. For instance, if you have a bug that you were unable to solve but you made progress, write that here. The more you articulate the problem the more partial credit you will receive (it is fine to leave this blank).
Assignment Rubric
| Description | Pre-Emerging (< 50%) | Beginning (50%) | Progressing (85%) | Proficient (100%) |
|---|---|---|---|---|
| Human-Centric Design (20%) | A trivial application of the modality is provided without regard to proper signifiers or affordances to facilitate human interaction | Some consideration is given to the manner by which augmented reality is incorporated into the program, but it is not clear at all times to the user what to do and how to interact | The user is able to interact with the program using augmented reality in most cases, with a few minor ambiguities that could be identified through additional testing | The user experience is enhanced by the use of augmented reality |
| Design Report (20%) | No design report is included | A design report is included that describes the approach taken to solving the problem and incorporating augmented reality in a trivial way | A design report is included that describes the approach taken to solving the problem and incorporating augmented reality in a manner that carefully considers the problem from the perspective of one stakeholder | A design report is included that describes the approach taken to solving the problem and incorporating augmented reality through documented discussions and test cases with a variety of stakeholders |
| Algorithm Implementation (30%) | The algorithm fails on the test inputs due to major issues, or the program fails to compile and/or run | The algorithm fails on the test inputs due to one or more minor issues | The algorithm is implemented to solve the problem correctly according to given test inputs, but would fail if executed in a general case due to a minor issue or omission in the algorithm design or implementation | A reasonable algorithm is implemented to solve the problem which correctly solves the problem according to the given test inputs, and would be reasonably expected to solve the problem in the general case |
| Code Quality and Documentation (20%) | Code commenting and structure are absent, or code structure departs significantly from best practice, and/or the code departs significantly from the style guide | Code commenting and structure is limited in ways that reduce the readability of the program, and/or there are minor departures from the style guide | Code documentation is present that re-states the explicit code definitions, and/or code is written that mostly adheres to the style guide | Code is documented at non-trivial points in a manner that enhances the readability of the program, and code is written according to the style guide |
| Writeup and Submission (10%) | An incomplete submission is provided | The program is submitted, but not according to the directions in one or more ways (for example, because it is lacking a readme writeup or missing answers to written questions) | The program is submitted according to the directions with a minor omission or correction needed, including a readme writeup describing the solution and answering nearly all questions posed in the instructions | The program is submitted according to the directions, including a readme writeup describing the solution and answering all questions posed in the instructions |
Please refer to the Style Guide for code quality examples and guidelines.
