Question

Consider requirements and technology for an analysis of an Automated Teller Machine (ATM) design. Type an outline out for an ATM system design using the below HCI criteria. Use eye-tracker data to further analyze the product Consider accessibility (universal usability) issues such as lighting, physical placement of ATM, etc. Consider user profile issues, e.g. is this the first time a user is using an ATM? Requirement to perform beta and/or market tests? Are there other stress factors such as a looming time deadline or a personal safety issue.

Hi,

Please find the answers below:

-----------------------------------------

Eye tracker data allows the design team to know where the end-user is looking or making the eye contact at the ATM device. Natural interaction with the ATM by the user occurs if the key controls are placed where most users look at.

Eye gazing varies from user to user. Many factors affect the way people look at the ATM.

For example: user’s height, mood etc.

ATM should be placed where there is good lighting , power control and ventilation. Temperature should be regulated with appropriate cooling system ideal for running the ATM machine. ATM should be placed at a level that is comfortable to ideal end- user height (ergonomics needs to be considered). This allows easy interaction with the ATM. ATM should be placed in a separate room, with closed door, enhancing security for the user.

----------------------------------------------

ATM design should be cognitive that allows novice user device interaction easy.

Ease of use

Important Usability use cases like inserting card, collecting cash from the ATM, touch points etc should be obvious for the first time user.

Help messages

The ATM user interface should display help messages to make the device interaction easy for new users.

------------------------------------------

Beta testing are field tests that are performed by real users of the ATM to assess the usability, functional and other aspects to the ATM device. This allows the designers know how the device is used by the diverse population like non technical users as well.

These tests happen at uncontrolled environment and not under the hood of designers, developers of the ATM device. Poor HCI aspects should NOT block these tests.

-----------------------------------------

Personal safety issue: The design of the ATM body, placement, end user interaction and the room should be able to be captured by CCTV camera. Bank authorities should surveillance the live footage and past interactions of the ATM.

----------------------------------

Hope this helps
