Assignment 3 Out - Please refer to moodle to download this assessment.
Output:
monitor or print eg logical sequence, layout, colour, orientation;
In some cases there can instances where users do not require a computer to output an image, there are printer systems that have a card or input reader that then enables the user to select the file that they wish to print and then have it output.
As can be seen in the image above this printer also has the ability to output images from USB storage also. The strengths and benefits of using these types of devices are that they are simple and intelligible to the use of how to operate them.
The boots printer systems also operate on this logic.
Issues that link to vision and the technology available
Research what the costs are of current specialist equipment.
Issues Involving Mobility/Motor Impairment
Conditions that affect a person’s ability to use keyboard and mouse effectively can be caused by:
- Diseases: arthritis, muscular dystrophy, multiple sclerosis
- Stroke
- Injury
- Loss of limb
- Repetitive strain injury
- Natural ageing processes
use of other devices eg voice output, projector/interactive whiteboard
The other tools that use on-screen interfaces are data projectors, these enable the users to select sections of the projected screen to trigger actions. These interactive whiteboards work by using pens or styluses to record the coordinates of the point in which the pen touched the board. These menus that are used contain further functions and features that are stored on a computer, which, give users the ability to write, underline and save text. The software on these interactive boards has the ability to turn written handwriting into text.
Testing:
user testing; against original specification;
A key point of any project, product or design is the testing stage, at this point, it is vital to check a number of areas. The areas that should be considered would be;
- Functionality
- Testing against the original specification
- Accessibility
The three identified areas above require the user to have an understanding of the purpose of the entity being tested. As mentioned in previous weeks, if you have no targets/outcomes identified how would you know what you have achieved, or, whether you have achieved.
Recording of this information in a log or table is the best method. This structure will provide users and other testers to understand what has been done and the results of the tests. The more information that is/ can be, recorded the better as this will provide starting points for any potential improvements or updates to be implemented quickly.
Working within a closed system;
Dependant on the product testing can vary. When working on or within a closed system the testing will be looking at and be subject to the internal mechanics of the system that it is in. For example, the internal clock of the computers requiring a power source to keep it operating, or correct, (Normally a small 5 Volt battery is used)
Working in wider system;
Recording Tests
Some software is available to systems developers and designers to record user interactions, this is useful as it will enable them to understand whether the movement of users is inhibited by any misunderstanding or interpretation to what is expected of them. Times and timings are used as primary indicators of user confusions.
Create a test table/plan for any system that you are likely to produce in your projects and assignments, this can be generic in places, such as buttons and images.
Using the interactive feature below, count how many powerpoint slides that you would need to reproduce this in Powerpoint. This will enable you to fully understand how many slides you are likely to require for your system to work.
