O K A Y?_App Recommendation Yihan

O K A Y? is a game that refreshing break away from the typical mobile games that are released. First of all this game received a 5 star rating from me as a result of its overall composition as a game. Artistically this game is great and uses a minimalistic style. It also incorporates a clever use of sound throughout the game that brings a delightful mechanic to the gameplay that compliments its artistic endeavors. Whereas the gameplay isn’t particularly deep or necessarily revolutionary its creativity and overall assembly stand out from it’s peers.

– They feel nervous when accidentally trigger the cooking instruction where time automatically starts count down.
– They want to go back once they accidentally start the cooking instruction but there is no back button.

– Instead of showing name and time simply, add ingredients for users to prepare before cooking.
– Give the start control back to users.
– Add one screen for step 2 for a more clear expression of the UI design.

Prototype#3 in Flinto

In the first two versions, there were two main problems that I worked hard but did find effective solutions. How to shorten the time and save energy of ingredient information in-put? it’s maybe significant to solve the essential pain points. Two new founds actually inspired me to reconsider the whole process.

1.Countertop&Prep Pad
Countertop is an app to measure the calories of food by using a bluetooth-connected scale called Prep Pad. Every time when user put food on the scale, the information will automatically be transferred to the app. So the user can manage the calories input easily through a dynamic visualization.
Cloudsight is an api that helps to recognize images.
So my idea is to combine the two functions: users put food on a scale at the same time focusing the camera to the food, then the weight and food information will be displayed at the same time.

Changes for third version
1.Reconsider the hierarchy,change it into four main functions
2.Simplify ingredients in-put to “put on the scale, select ingredient”
3.Instead of listing every certain ingredients, I change the inventory into just displaying the class of ingredients
4.Change the hamburger menu into a circle icon on the left top



Update on final prototype Mar 27, 2015

-Reconsidered the first screen when first-time users start using this app. Lead them to add their ingredients before browsing the recipes.
-Changed the “Add new ingredient” as a part of Inventory interface.
-Rearranged the inventory to alphabetic way.
-Added a “taking photo” screen with black background before entering the “Add New Ingredient”, making this function more clear and the polished banana image less confusing.
– Designed a logo for the app. Change the menu icon of “Preference set” screen to it, differentiating with the icon of Landscape Mode.
-In the screen of recipe: changed the position of Save button and Landscape Mode to the right bottom of the food picture.changed “try it” at the bottom to “landscape mode”, add “try the landscape mode” at the position of direction.

CookSmart Prototype #2

After the first paper prototype, I re-design my idea with all the feedbacks. Also enhanced the interface.
-Change the home page from preference set to inventory content, so the users will more easily manage their food. Also the magnifying glass on the right top is designed for user to search a certain food if they have numerous ingredients.
-When users tap on one ingredients, it jumps to the preference set interface.
-Add a button at the bottom for adding new ingredients.
-Linked all functions to a hamburger bar on the left so the user will know where they are.

Things I learned from second time paper prototype
-Keep working on hierarchy
-The hamburger bar does not work well, it’s still confusing while jumping to the preference set interface.
-Still, shorten the process of in put ingredients.

User Test

Things I learned from first time paper prototype
-Reconsider the hierarchy so the user can know better why they are on this app.
-Instead of showing the simple version of recipe, just directly lead users to the full version of recipes.
-Simply “Ingredient-input” as much as possible, do not create more pain points while solving the problems.
-Think deeper with the essential logic of “Tinder design”
