Assignment 1 - Memory Training Game
ENG1003, Semester 1, 2019
Due: Friday 5th April 18:00
Worth: 12% of final mark
For this assignment your team will develop a memory skill game based on the electronic game Simon, produced
by Hasbro. You will create a web app that displays random sequences of colours which the user must repeat
from memory. As the user continually enters correct sequences the game progressively selects longer sequences.
Background
Simon is a 40-year-old electronic game, currently produced by Hasbro (https://en.wikipedia.org/wiki/
Simon_(game)). The game has four coloured buttons that light up and play a sound in sequence. The user
then has to replicate the sequence by pressing those buttons in the same order. The sequences become progressively
longer and more difficult until the user is unable to repeat the sequence and the game ends.
While such games are entertaining, the complexity and randomness of the sequences also allows the game to
be used as a means of practicing memory storage techniques. There is some evidence that individuals with
mild cognitive impairment can benefit from memory enhancement training1
from games such as Simon.

1
Your team has been hired by Thoughtress, a small firm that develops memory skill games for researchers
and individuals to evaluate improvement in memory ability. Normally they develop these games as physical
electronic devices, however they wish to make their services more accessible to those in rural areas. To this
end your team has decided to develop the game as a mobile web app.
Background: Example sequences
Below are some example sequences that might be shown when playing the game:
Seq#/Pos colour 1 colour 2 colour 3 colour 4 colour 5 colour 6 colour 7 colour 8 . . .
Seq1 Red Red Red Red
Seq2 Red Green Blue Green
Seq3 Blue Green Yellow Yellow Blue
Seq4 Green Yellow Red Blue Red Green Blue Red
Table 1: sample colour sequences
Background: Game progression
The difficulty level (sequence length) increases after the user gets a certain number of sequences of that length
correct. The number of correct sequences needed to advance is shown in the table below. (The number is
always two less than the sequence length.)
Sequence length
(level)
Correct sequences
needed to advance
4 (initial) 2
5 3
6 4
7 5
8 6
etc. etc.
Table 2: sequence length progression table
For example, at the start of the game, the player is given sequences of length 4. The player receives RRGB
followed by GGBY and they get both correct. Since they have entered two sequences correctly, the game now
increases to sequences of length 5. The player then receives YYGBR (a sequence of length 5) and needs to
enter 3 of further correct sequences to advance to sequences of length 6.
2
Any time the player makes a mistake, they start again at the previous level (or reset to level 4 if they make
two consecutive errors). The player cannot be given sequences shorter than 4 (as this is the starting level).
Background: Angles obtained from the phone using device orientation
There are some situations where it may be too difficult for the user to interact with the app using the buttons
on the screen (for example while wearing gloves). As such, we want to allow users to control the app using the
phones orientation.
When using device orientation there are three angles that you have access to: alpha, beta and gamma; where
beta represents the forwards-backwards tilt of the phone. It can visualised as below:
Figure 1: side view of phone at different beta angles
In figure 1, where we are looking at the phone from the side, this means that when the device is flat on a
surface, screen facing up it will have a beta of 0 degrees, tilting the top of the phone down gives a beta of -45
and tilting the top of the phone up gives a beta of +45.
In figure 2, where we are looking at the bottom of the phone, being flat on a surface gives a gamma of 0
degrees, tilting the phone to the left gives it a gamma of -45 whereas tilting to the right gives it +45 degrees.
You can observe these Beta and Gamma values on the team phone using the ENG1003 Sensor Test app:

What you are provided with
We have provided a skeleton version of the app, which displays the basic interface of the app and includes:
Code that triggers the userChoiceTimeout function in gameLogic.js
– This function is called when the user fails to make a decision after 2 seconds.
Code to trigger the giveNextSequence function in gameLogic.js
– The giveNextSequence function will be called automatically every time the user clicks on the play
button.
– This function should return a list of strings which can include the following:
“blue”
“green”
“yellow”
“red”
For example [“blue”,“blue”,“green”] which would correspond to a sequence of Blue Blue Green
Code to trigger the sequenceHasDisplayed function in gameLogic.js
– This function is called when the sequence that has been returned by the giveNextSequence function
has finished being shown to the user.
– This is an opportunity to display information to the user prior to them entering a sequence.
Code to trigger the changeMode function in gameLogic.js
– This function will be called when the user switches input modes between touch input and tilt input.
The initial input method is touch.
– This function has a parameter mode which will contain TOUCH MODE or TILT MODE depending
on the mode the user has just switched to.
4
The showSuccess and showFailure functions
– These functions can be called by your code to display an image of a tick or cross based on whether
the user has entered a correct or incorrect sequence.
– The tick or cross will automatically disappear after one second.
Four coloured buttons arranged in a circle on the screen
– These buttons are designed to be clicked (or tapped on) by the user.
– When clicked, each of these buttons will result in a call to the buttonSelected function in gameLogic.js
– When the buttonSelected function is called, it will be passed with one of the following strings as an
argument representing which of the four buttons was clicked on:
“blue”
“green”
“yellow”
“red”
A Play button on the app’s title bar which displays the next sequence for the user to enter and results
in each request to your giveNextSequence function.
A displayToastMessage function which you can call to have a “toast” message pop up at the bottom of
the screen to notify the user of some information.
Other than this, you don’t need to know anything else about the skeleton to use it. You need to implement
the functionality described below.
The app skeleton can be downloaded from the ENG1003 Moodle site. The app skeleton is titled assignment1.zip
and contains a file gameLogic.js where you should write your submission.
You don’t need to understand the other files we provide you with as part of the project skeleton – they include
some concepts we haven’t yet covered.
What you need to do
Getting started

1. As a team you should download a copy of the project skeleton and unzip this.
2. The assignment1 folder contains the code of the web app.
3. Open the gameLogic.js file. You will implement your solution in this file.
   5
4. The gameLogic.js file can be uploaded to the ENG1003 web server via the ENG1003 Assignment
   Uploader web page (see below) and run on your team smartphone.
5. You should discuss within your team on the breakdown of coding features and practice pair programming.
6. Plan to have steady progress rather than completing the assignment at one go, or to do it at the last
   minute.
   Programming Tasks
   The Programming component of this assignment is worth 9% of your unit mark.
   For the programming tasks, we suggest you complete each part together before moving onto the next one.
   Feature 1: Generating random sequences
   The first step to displaying sequences on the screen is to generate those sequences. This should be done in the
   giveNextSequence function and returned as an array of strings. You should use the random method of the
   Math package to produce random numbers to represent any given option. Note: Your code will need to save
   the generated sequence for checking against the sequence entered by the user.
   Feature 2: Sequence input
   The buttonSelected function will be called every time the user clicks on one of the coloured buttons. You
   should keep track of which buttons the user presses and the order they were pressed in.
   Once the full sequence has been entered, you should compare what the user has entered against the original
   sequence. If the sequences match then you should call the showSuccess function, otherwise you should call the
   showFailure function. (Both functions are part of the app skeleton.)
   Feature 3: Increasing difficulty level
   You should keep track of how many consecutive sequences the user has entered correctly at the current level.
   When the user gets enough correct in a row (see background, game progression (page 2)), the game should
   advance to the next level.
   6
   Feature 4: Resetting difficulty level
   If the user enters an incorrect sequence, they should be taken back to the previous level. For example, if they
   provide an incorrect sequence for a sequence of length 6, they need to do sequences of length 5 again (3 of
   them) before they get a sequence of length 6 again.
   If the user makes two mistakes in a row, they are reset to the starting sequence length of 4.
   This means that you will need to track the level the player is on and the number of successful/unsuccessful
   sequences entered.
   Feature 5: Displaying status and progress
   You should show on the screen (via the label with the id ‘output’) the current progress of the user, including:
   Number of items remaining to be entered for the current sequence.
   Length of the current sequence
   Number of correct sequences entered at the current level
   Remaining additional correct sequences until they advance to the next level
   You should also display general status such as whether the user is currently expected to enter a sequence or
   watch a sequence.
   This progress information should be updated whenever any of this information changes.
   Feature 6: Tilt-based input method
   You should add an alternative control scheme where the user tilts the phone towards the button they wish to
   light up. In order to do this, the app must be able to respond to changes in the orientation of the device using
   the DeviceOrientation event. See the Background “Angles obtained from the phone using device orientation”
   section (page 3).
   The app has a button to switch between input modes which results in a call to your changeMode function
   which has a parameter mode which will either be TOUCH MODE or TILT MODE depending on the mode.
   You may need to remember this value in your code.
   7
   You should modify your app so that it can track the orientation of the phone. When the phone is tilted toward
   the bottom-left of the phone this should be treated as the user attempting to select the bottom-left button
   (i.e., the yellow button). Likewise for the other three buttons.
   There is already code in the main.js file (supplied with the skeleton) which triggers the buttons to light up
   and runs the buttonSelected function (that you’ve already implemented). Each of these functions are named
   for the corresponding buttons they light up: selectYellowButton, selectRedButton, selectBlueButton or selectGreenButton
   (also aliased as selectBottomLeftButton, selectBottomRightButton, selectTopLeftButton and
   selectTopRightButton).
   The DeviceOrientation javascript event will notify you (via a callback function) whenever the device orientation
   changes, but this might be many times a second. For this reason we don’t want to select a button as a
   result of every orientation change, but rather just store the button that would be selected, and then we can
   actually register this selection after the standard button press timeout occurs (i.e., a call to your userChoiceTimeout
   function). Hence, if the app is in tilt control mode when your userChoiceTimeout function is called
   you should see if the phone is tilted and if so then select the appropriate button.
   Feature 7: show tilt while in tilt mode
   While the app is in tilt mode, you should ensure that you display the current tilt of the phone visually.
   This should be done in such a way that it’s clear to the user which button will end up being selected on
   userChoiceTimeout.

   Presentation
   This assignment includes a presentation component worth 3% of your unit mark.
   Thoughtress have had their representatives look over the app your team has produced and are pleased with
   the results however despite initially agreeing with your team’s suggestion of a mobile web, they now ask your
   team to get the app in the Google PlayTM store and Apple AppStoreTM. In other words they are asking
   your team to completely redesign the app as a native app for android and ios devices. Your team has little
   experience with iOS apps however you have worked closely with another organisation (IntellAppt) in the past
   with extensive experience with both Android and iOS development environments. After some negotiation, it
   is agreed that IntellAppt will handle this redevelopment while your team takes more of a support role and a
   handover presentation organised for three weeks time.
   In your Week 6 prac class your team will deliver a handover presentation. Your team should present an
   overview of the functionality, design of the code and any specific hardware requirements. You should warn the
   new team about any current issues in your app as well as provide any suggestions for improvements. As with
   any good presentation, it should be prepared well in advance of the due date (including any visual aids) and
   it should be well rehearsed as a group and individually.
   Format
   Each student team will deliver a 10-minute oral presentation (in prac class) describing and demonstrating the
   functionality of their app and detailing any limitations of the application. Every member of the team should
   present for 2-3 minutes.
   The target audience for this presentation is another team who will be extending the project further.
   This presentation would be delivered in a formal business setting and so all team members should be
   dressed appropriately.
   This presentation must discuss the structure and functionality of the application as well as any design
   decisions made.
   Testing the app
   Upload your code to the ENG1003 server using the assignment upload page. The uploader can be found here:
   https://eng1003.monash/uploader/
   Once you have uploaded the code, you can view the uploaded assignment by selecting the appropriate assignment
   from the dropdown list on the assignment viewer. The viewer can be found here:

   Submission
   Your team should submit their final version of the application online via Moodle. You must submit the
   following:
   A zip file named based on your team (e.g., “Team014.zip”).
   This should contain ONLY one file named gameLogic.js
   This should be a ZIP file and not any other kind of compressed folder (e.g. .rar, .7zip, .tar).
   The submission should be uploaded by the team leader and must be finalised by Friday 5th April 18:00 (local
   time). Please note: Your entire team needs to accept the assignment submission statement individually on
   Moodle.
   You also need to individually complete the CATME peer assessment survey as described below.
   You also need to individually complete the following tasks:
   CATME peer assessment survey
   Assignment code interview
   Your presentation will be given during your practical classes in Week 6 (8th - 12th August 2018).
   Marking criteria
   Programming tasks
   Your assignment will be assessed based on the version of gameLogic.js file you submit via Moodle. Before
   submission check your code still works with the original app skeleton, in case you have modified your copy of
   any of the other files. We will run it with the original app skeleton and test it on your team smartphone. We
   will use the same phones when marking your assignments.
   Assessment criteria:
   Whether the app functionality satisfies the assignment specification
   Quality of app source code, including structure and documentation
   10
   You will be marked as a group, however your individual marks will be subject to peer review moderation based
   on CATME feedback and your assignment interview.
   A detailed marking rubric will be available on the unit Moodle page.
   CATME Peer assessment
   You are expected to work together as a team on this assignment and contribute roughly equal amounts of
   work. Peer assessment will be conducted via the CATME online system. You will receive email reminders at
   the appropriate time.
   Not completing the CATME peer assessment component may result in a score of zero for the assignment.
   Do:
   Give your teammates accurate and honest feedback for improvement
   Leave a short comment at the end of the survey to justify your rating
   If there are issues/problems, raise them with your team early
   Contact your demonstrators if the problems cannot be solved amongst yourselves
   Do NOT:
   Opt out of this process or give each person the same rating
   Make an agreement amongst your team to give the same range of mark
   Assignment code interview
   During your Week 6 prac class your demonstrator will spend a few minutes interviewing each team member
   to individually gauge the student’s personal understanding of your Assignment 1 code. The purpose of this is
   to ensure that each member of a team has contributed to the assignment and understands the code submitted
   by the team in their name.
   You will be assigned a score based on your interview, and your code mark will be penalised if you are unable
   to explain your team’s submission:
