You are being employed as a novice interaction designer on a project to develop a public kiosk providing information about the exhibits available in a science museum. Consider how you might implement each of the four ID activities. For example, you might observe users as a part of establishing requirements. As it is still early in the module you will need to use your imagination and experience when answering this question, becausewehavenoty etc overed thevariousa pproachesi n any detail.Do not be concerned if your suggestions are different to mine - you will learn more about the approaches I suggest later in the module.T he purpose of this activity is to get you thinking about what an interaction designer might need to do.
