Will help us use the knowledge we gathered from previous experience and apply it to similar situations

Allow us to use our intuitions which are based on previous experience and logic; if something is consistently done in a particular way, it will eventually become the conventional way of doing it

Will involve limiting the actions that can be performed in a particular design

Safety in data means, preventing user from making serious errors by ____________ of wrong keys/buttons being mistakenly activated

Norman's Principles of Usability, ______________ is restricting some kinds of user interaction to take place at a given moment

Norman's Principles of Usability, _________________ is exploit people’s common-sense reasoning about actions and their consequences

Can reduce both learning time & errors

The system should be easy to learn so that the user can rapidly start getting some work done with the system

It will be easier to remember if a particular object is placed in a consistent location, e.g., always putting the search box in the upper right-hand corner of a Web page

Allow more user control & accommodates variations in user skill and preferences, i.e., give users choices

Computer should respond immediately to a user’s input or inform the user when long delays are unavoidable

Protect users against disastrous results of common human error

We study HCI to determine how we can make this computer technology more usable by people.

HCI is the study and application of usability.

Safety in data means, providing user with means of recovering errors.

Safety in data means, ensuring publicly & security (protect sensitive information such as passwords, VISA card numbers.

Nielsen Norman Group: “provide a wide range of design services, in each case targeted to address the product development needs at hand”.

Constraints, allow more user control & accommodates variations in user skill and preferences, i.e., give users choice.

Norman's Principles of Usability, physical constraints rely on learned conventions.

Norman's Principles of Usability, avoidance mean to give clues to operations of things.
