Designing usable interactive products requires considering who is going to be using them, how they are going to be used, and where they are going to be used. what is a key concern in this activity?

The user experience or the user activities

Explanation:

One concern that must be considered when designing usable interactive products apart from the points raised here is that the user experience and the activities the user will be doing when they are interacting with the products must also be considered.
