Confirmations

Confirmation approaches can also be defined by Statements or Prompts , but when we talk about them in the context of confirmations we call them Implicit and Explicit.

Implicit Confirmation

This type of confirmation is also a statement. The idea is to parrot the information back to the user to confirm that it was correct, but not require additional input from the user. The implicit confirmation can be used in a majority of situations. For example Neon’s Timer Skill uses implicit confirmation when creating new timers.

Timer Skill

Speaker
User	Hey Neon set a timer for 5 minutes
Neon	Alright, I’m starting a 5 minute timer

Avoid

Speaker
User	Hey Neon, add bananas to my shopping list
Neon	done

Better

Speaker
User	Hey Neon, add bananas to my shopping list
Neon	Adding bananas

Explicit Confirmation

This type of confirmation requires an input from the user to verify everything is correct. Only use explicit confirmation when needed as it can be tedious for the user to always confirm their input. This strategy is best when there are multiple steps, and it would be difficult to fix a misstep without starting over, or when deleting or modifying an existing multi-step input.

Avoid

Speaker
User	Hey Neon, set an alarm for 9:00 am tomorrow
Neon	Ok, I’ve set an alarm for 9:00 am tomorrow, is that correct?
User	Yes
Neon	9:00 am alarm set

Better

Speaker
User	Hey Neon, set an alarm for 9:00 am tomorrow
Neon	I've set an alarm for tomorrow at 9:00 am, 16 hours from now

The first example requires the user to confirm the alarm. Since the interaction is quite short it isn’t necessary to use explicit confirmation.

Avoid

Speaker
User	Hey Neon, set a calendar event for a meeting with Chris Stevens
Neon	When is the event?
User	Tomorrow at 11:00 am
Neon	should I send an invite to Chris Stevens?
User	Yes
Neon	Alright, I've created a meeting for Tomorrow
Neon	Alright, I’ve created a meeting for Tomorrow at 11:00 am with Chris Stevens
User	Cancel my 11:00 am meeting tomorrow
Neon	Done

Better

Speaker
User	Hey Neon, set a calendar event for a meeting with Chris Stevens
Neon	When is the event?
User	Tomorrow at 11:00 am
Neon	should I send an invite to Chris Stevens?
User	Yes
Neon	Alright, I’ve created a meeting for Tomorrow at 11:00 am with Chris Stevens
User	Cancel my 11:00 am meeting tomorrow
Neon	Are you sure you want to delete your meeting tomorrow at 11:00 am?
User	Yes

Both examples use explicit and implicit confirmation correctly until the end of the interaction when the user wants to cancel the event. Unlike setting a simple timer or an alarm creating this calendar event requires multiple steps and would require reasonable effort to recreate. There may also be significant consequences if the request was misinterpreted and the meeting was cancelled unintentionally.
