Smart Kitchen products & Concepts
Similar to the Amazon Dash button, GeniCan sits with your garbage can to make sure you never forget the groceries you need.
To add items to a shopping list, you simply swipe the item's barcode code on GeniCan's barcode reader. You can then find the item added to a list on the GeniCan app on your smartphone.
If the item doesn't have a barcode, hold the item (or your hand) in front of the scanner for a few seconds. When GeniCan does not sense a barcode it will ask "What may I add to your list?" and you can tell it to add mac 'n cheese, or whatever you want.
If you're used to inputting all your caloric intake through various food tracking apps, then SmartPlate wants to make your life easier. The 10-inch plate is Wi-Fi and Bluetooth-enabled and, get this, it comes equipped with three mini cameras and weight sensors. Basically, your dish will be watching you - or in other words, figuring out what you're eating and doling out proper portions.manually. If you serve yourself too much, the plate will alert you. There's also an app that syncs up with the plate to automatically analyze and keep track of every meal, and connects to MyFitnessPal & Fitbit.
Not quite as hi-tech as LG's tech-tastic cooker but nifty nevertheless, this crowdfunding success story will keep count of your eggs - up to 14 - letting you know (using LED lights and the companion app) which ones are the oldest and which ones might be going bad.
Essential reading: Best smart home tech
Whats more, it's IFTTT compatible, so you can set up some interesting IoT combos. For example, "If I run out of eggs, play I am the Walrus on Spotify".
Drop scales will have you baking like Mary Berry in no time. You simply select your chosen dish from a companion app's recipe book and these connected scales will help you put together the exact ingredients to make your bake a great success.
The recipes are all one-bowl affairs, so less washing up after, and the app will even offer up alternatives ('smart substitutions') if you haven't got quite enough of one ingredient.
Highlights from reading - Chapter 2
Avoid cognitive overload by Creating rich VUI experiences. Using both voice commands and visual Solutions at the same time during voice Journeys. It's important to build the voice commands as well as the mobile app at the same time.
The number of interactions in a user has with a VUI is known as a “turn”. Most user interactions are a single turn.
Conversational design - conversational designs include multiple turns Beyond one and as many as four or five. Most conversational Design Systems are not capable of holding conversations Beyond two or three turns. Example, Figure 2 - 4 Page 19
* Completing a conversational design to the user can be an endorphin rush and prompt the user to continue forward down the path.
Unnecessary verbiage - Design with breadth in mind Example P.20 It's not always necessary to give a confirmation to a user during a conversational turn. For instance, when setting an alarm, instead of telling the user that the alarm was successfully set to consider saying starting a timer for 10 minutes. By telling the user you're starting the timer you're also telling them that the alarm was also successfully set. Using breadth allows the user to make assumptions and thereby reducing the number of turns necessary for the conversation to be successful.
*Don't forget the corresponding task. If you can set an alarm to make sure you designed for being able to cancel the alarm.
Leverage in common vocabulary or terminology can be valuable in certain instances like taking a picture. Example: P. 21 “1,2,3... Cheese!”

Smart Kitchen Product Research
After looking at over 50 different refrigerators at Best Buy, a local store for consumers at the mid-market level to purchase from, I finally settled on a Model I thought most appropriate based on it price point, style and appeal, and features and functionality. The model light shows was the LG LFXC24726S At a price point of $2,400, This refrigerator seems to be at the right price with the right features in to suit an early adopter target audience seeking a smart refrigerator fully stocked with Alexa connections to your Amazon Prime and Amazon Fresh accounts.
