In this assignment you will first select an example humancom

In this assignment you will first select an example human-computer interaction using direct manipulation or immersive environment. [10] Which system have you chosen? Be very specific about your chosen system (e.g., URL if the system is Web-based, name, version, operating system if applicable, year of publication) [10] How does the system you have chosen demonstrate the three principles of direct manipulation? [10] How does the system you have chosen demonstrate some or all of the beneficial attributes of direct manipulation? [10] What is the translational distance of your system? Support your answer with very specific reasons for the translational distance you specified.

Solution

Example 1:

In human computer interaction the best example for using the direct manipulation is \"TRASH\" on the desktop within the computer system.In this user can see both the trash and files they want to move to the trash.The user can easily drag or move the file into the trash by using the mouse. Now see some principles which are used to direct manipulation.

Example 2:

This is another example which is we can daily use that is playing a song by using controls like tape or CD/DVD and deck players.

Principles:

1.Process based on the selection and visible and interrupted performance of objects.

2.The second principle most faster than the previous principle so process based on selection immediately displayed and it is two sided action.

3.This last one does not have any syntax so process based on the selection using pointing action instead of typed commands

These are three principles for direct manipulation .

Attributes of direct manipulation system:

1.Editors

2.Word processors

3 Spreadsheets

4. Visual data base system

5.Video games etc.

Translation distance of your system:

1.The people living in country side need an effective long distance medical services are very important so they need to interact with the doctors who are working in modern city.So to address this problem we need multiple translation system for long distance for medical and patients services .This system can translate any language into other language by using machine translation system.It translates the sentences selected form the table and translates by using machine translate system.
