How can we measure the effectiveness of the design tools?

The methods to asses the user-friendliness of a system can be divided into two types: ❔❔❔ and ❓❓❓

Current ❓❓❓ technology, however, cannot detect subtle disruptions in the motion that may be associated with early diseases.

❓❓❓ can influence users’ acceptance and adoption of information technology.

This component automatically collects the messages that use the native❓❓❓ of the platform.

One possible ❓❓❓is that the method doesn’t involve the use o f the interface in the way it would be used in real life.

It’s important that the evaluators work independently, so that they don’t ❓❓❓each other

Emergency cooling systems could fail and a reactor meltdown could ❓❓❓.

We can only ❓❓❓ system logs to tell us what has happened, not necessarily why it has happened.

System logging can also show any tasks which the user ❓❓❓ to complete.

It’s important ❓❓❓ exactly where problems are in the usability.
