Echo Buttons present some interesting opportunities:

• Toy makers can add these to their devices for Skills/toy interaction
• Skill builders can use them for lighting or communication
• New skills like fitness skills can use these (think about burpee exercises where you slap after each rep)
• Furniture and appliance can incorporate these

Perhaps in the future third party devices can be used as the button, similar to how there’s a Dash replenishment API that works like the Amazon Dash button.
