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

{color:#000000}This design was focused on...{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.

{color:#000000}This is the design overview{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 ctl or alt key is pressed, the overlay appears again for the current page.


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.


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.

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.
