Grocery Guru Log

Week of Jan. 23 - Jan. 29

created our WikiPage
brainstormed ideas regarding nutrition, groceries, and efficiency
considered creating an iPhone app that reads the barcodes on food products, and used the codes to help the user live a healthy lifestyle
talked about the possible applications a health-related iPhone app could have in hospital use
decided to instead make an iPhone app that aids a shopper as they make their way through a grocery store, such as Schnucks
brainstormed a list of functions our app could perform that would aid the average shopper: speed through the store, ease in finding products, map of the store, what products are available for purchase, how long their shopping run will take, etc.

the three members of our team met up on Wednesday to draft an outline of our proposal
drafted an overview and brainstormed a list of challenges, objectives, and a budget
we were assigned Andrew O’Sullivan as a TA
met with Andrew on Thursday and finalized each the components of our proposal (mentioned in previous bullets
he helped us brainstorm ideas for our demo in order to make it interactive
with Andrew's help, we learned the basics of how to create an iPhone app, including the possibility of needing to obtain a developer's license

met with Andrew on Tuesday to discuss problems with our proposal
added the challenge and the objective to make our app able to scan a limited number of barcodes on grocery items, so that our project is able to carry out a demo rather than a simulation
Maggie researched app development and started working on an app developing lesson provided by Apple https://developer.apple.com/library/content/referencelibrary/GettingStarted/DevelopiOSAppsSwift/BuildABasicUI.html#//apple_ref/doc/uid/TP40015214-CH5-SW1
Amelia researched different apps that have similar capabilities to our idea, including the Schnucks app
Anna edited and revised our proposal

this week we addressed the problems Humberto brought up with our proposal
we switched grocery stores so that we can have access to a list of all the products and the UPC codes
we added access to an amazon cloud database to our budget to store the data that our app will utilize
updated the project proposal to explicitly say what the app interface will look like
updated "time" to an approximate time that will be spent in the store to account for users not following the routes perfectly
this week all of the team members were tasked with learning swift language and completing a tutorial that teaches how to apply swift to xcode to create an app interface
we used these two links: https://www.airpair.com/swift/complete-guide-to-swift and https://developer.apple.com/library/content/referencelibrary/GettingStarted/DevelopiOSAppsSwift/

we met with Andrew on Tuesday and made additional changes to the objectives of our project. These objectives are as follows:
we will now be using Paws 'n Go instead of Schnuck's; therefore, we can better track the inventory of the store and have easier access to the products and their barcodes
we decided the primary goal of our application will be to provide the user with an approximate total cost of their shopping list
each member of our group, without communicating with the others, sketched an outline of the design we envisioned for our application. We then compared each of our designs and compiled our favorite parts of each one. We will use our compiled outline as a guideline for our application.
each member of our team downloaded multiple barcode scanning applications to our mobile devices and tested which one ran the most smoothly. We did this by testing the scanner with products from WashU dining facilities as well as from local grocers
each member continued to study the Swift lessons provided by Xcode
Amelia updated the Gantt chart to reflect our final project ideas
Maggie obtained a list of all the custom labels for Paws 'n' Go premade items with the names of the items and barcode numbers
set up a meeting with Humberto for our first project proposal

met with Andrew and Humberto for the first evaluation to discuss the details of our app layout and goals
developed a target user for our app, which is aimed at students at Wash U that go to Paws N Go
defined a problem with Paws N Go, slow checkout and uncertainty of grab-and-go items in stock, that our app can solve
reorganized and changed our objectives to solve the problem
Amelia coded a barcode image generator that takes in a UPC number as a string
Maggie tested the barcodes generated from UPC numbers of grab-and-go items at Stanley's in Lopata Gallery, and it was a success!
Anna redesigned the layout and visual aspects of the application
