h2. Scenario

Carol Peterson is a retired materials engineer with five grandchildren and she always goes to the store to buy her weekly groceries. She knows exactly what she wants to buy, but would rather not have to go to the store to do it. She has been meaning to switch over to a fully online experience, but does not want to lose the human interaction that comes with going to the store.
Tasks:
# Search for grocery list item
# Reach some sort of customer service
# Check a review of the item
# Add to cart and have delivered bi-weekly

h4. {color:#800000}Design Overview{color}

{color:#000000}This design focuses on the common vision problem of the elderly. It address this issue through the use of large font and large images, among other techniques. {color}


h4. {color:#800000}Learnability{color}

This design addresses issues of learnability using clear transitions, visible icons with text descriptions, and large text. Specifically, the search bar is in the center of the page on the homepage, but when a search is performed it slides to the top bar. Icons and text are resizeable, and every button has an icon title.

h4. {color:#800000}Efficiency{color}

The efficiency of this design lies in its simplicity. Though initially emphasized for clarity and learnability purposes, the simplicity of this design means that fewer clicks are necessary in order to execute a purchase. On the item detail page, a sidebar on the right has fixed position (i.e. does not scroll with the page) so that if the customer decides he or she would like to purchase the item while scrolled down in the middle of reviews, he or she need not scroll back to the top of the page.

h4. {color:#800000}Safety{color}

The most important parts of safety in shopping are ensuring that nothing is purchased accidentally. To combat this, we have several features. First of all, the checkout process asks for confirmation. Secondly, adding to the cart asks for the quantity desired before adding.

Image 1: The main purchasing page 


h4. {color:#800000}Design Overview{color}

{color:#000000}This design was inspired by tablet interfaces and had the main focus of being as efficient as possible. Carol would search for the item in the search bar. She would then find the seller's customer service number in the item description and give them a call in order to have some of her questions answered. After that, she would look through the reviews below each item to make sure she was not buying something with low ratings. She would then finally add it her shopping cart on the left and continue shopping. {color}


h4. {color:#800000}Learnability{color}

In order to facilitate the learnability of the keyboard shortcuts, which are a focus of the design, we have an initial overlay on the site with the keyboard shortcuts enumerated. Additionally, whenever a ctrl or alt key is pressed, the overlay appears again for the current page. This page has many external consistencies seen in other shopping websites like amazon.com. 


h4. {color:#800000}Efficiency{color}

The focus of this design is efficiency, and as such keyboard shortcuts are prevalent. Additionally, almost all of the functionality is located on one page in order to facilitate fewer clicks.The shopping cart is static on the  The process can be done entirely through voice, so users with impaired visual ability can still perform shopping tasks.left side for easy access and quick modifications to current orders. Related search results make searching for a certain product efficient.  


h4. {color:#800000}Safety{color}

This design is safe in that there is a keyboard shortcut to undo any action. Additionally, any keyboard shortcut which is pressed is shown on the bottom. The shopping cart is easily modifiable and any accidental purchases can be quickly and easily undone.

h4. {color:#800000}Design Overview{color}

{color:#000000}This design revolves around voice interaction. It's primary audience was older people that have poor vision. These users would not be conducive to heavy graphical/text interface. In this design the shopping is automated, and the users interact with a digital assistant. The assistant asks the user a series of questions in order to narrow down their selection. The system can direct the user to customer support if more advanced guidance and/or help is needed. The transcript of the conversation is displayed on the screen.{color}


h4. {color:#800000}Learnability{color}

Upon first entering this site, an audio tutorial is given with available keyboard commands and navigation tips. Furthermore, the command “help” can be issued, and all the voice and keyboard commands will be read out. This interface has very good learnability, since talking is a natural way of interaction. Also, if the user still has issues with interaction, the system can connect the user with customer service.


h4. {color:#800000}Efficiency{color}

This design is keyboard and voice-centric, and as such does not require precise mouse movement. Though interaction with this design is simple, efficiency is hampered. Conversing with an automated machine is much slower than keyboard and mouse navigation since the user must partake in a back and forth conversation. What's more, is that a new conversation must be had for each item bought. Buying a multitude of different items using this interface will likely be a very slow going process. More expert users may not find this interface fast enough. 


h4. {color:#800000}Safety{color}

An “undo” command can be issued, which will undo the last action (and read out what action has been undone). Thus, accidental/inaccurate responses can be reverted with the click of a button. Also, since the conversation is also outputted to the screen, if a user forgets where he/she was during the transaction process he/she can simply read over the transcript.
