I believe that robots should only have faces if they truly need them

Too many companies believe that all they must do is provide a 'neat' technology or some 'cool' product or, sometimes, just good, solid engineering. Nope. All of those are desirable (and solid engineering is a must), but there is much more to a successful product than that: understanding how the product is to be used, design, engineering, positioning, marketing, branding-all matter. It requires designing the Total User Experience.

In design it is important to shoe the effect of an action. ... Feedback is critical.
