• Easier to learn for a novice user • More intuitive to use • Similar to othr packages which user may be familiar with • Help/Tutorial • Can Customise desktop • Onscreen keyboard • May lack advanced features

• Allows unusal commands, not available on GUI • Runs quicker than a GUI • Efficient for experienced user • May take a novice a long time to learn

• Cursor may move automatically tot he next input field • Intuative to fill in • Allows changes to be made while screen is still visible • May include inbuilt validation, only certain entries are allowed

• Speech and linguistics are used to interact and control a software • Doesnt require a keyboard or remote control • No training required • Hands free • Faster than typing • Very complex processing needed • Slang • Noisy environment • Could be a security risk

Relies on intuitive actions related to natural everyday human behaviour - Touch screens - Gesture recognision - Speech recognision

Places one or more of the users senceds into a computer generated virtual environment • VR • Force Feedback • 3D Sound

• Speech recognision • Head/Eye movement • Screen Reader • Foot Controlled keyboard • Oversized keyboard • Adapted screen output • Head Stalk • Braile Overlay/ Printer

• Checking the correspondence between the actual design and its obvectives • Confirm that the most appropriate techniques have been used • Confirmt hat the HCI is appropriate

evaluate the solution against the original requirements, all requirements should be met for a solution to be successful

Evaluate the solution against cost which include financial costs, human costs and resource costs. Solution must not exceed an negotiated costs.

evaluate the solutions against its test results. A solution should use error trapping and validation methods to be successfully rebust and reduce the chance of system errors and failures

evaulate the solution against the ease of sue for the end user. Solution should use an intuative user interface suitble for the end user

Evaluate the performace of the solution, should be fully optimised to reduce memory suage. Solution should complete specific task within a given time frame to be successful
