CAN’T AFFORD TO OVERLOOK THE ACCESSIBILITY

Some gestures might not be possible for users with disabilities. Therefore you can’t do away with the support for assistive technology like Joysticks or electronic pointing devices.

MY FAT FINGERS

Fingers and thumbs are your direct link to touchscreen devices. Therefore, interfaces should be designed keeping the size of touch targets large enough to respond to fat fingers with enough space given to not accidently tap the nearby links.

ONE SIZE FITS ALL

The new age interfaces will come in different shapes and sizes, could range from large industrial size installation to smart appliances to smartphones. Designers have to consider all size requirements even when there is ‘no shape’ involved.

KEEP THE CONNECTIVITY IN MIND

The internet connectivity reach and speed is not good in developing countries and therefore the design interfaces should be able to work in low connectivity.

POWERFUL PROCESSING

NUI systems are bound to be really complex and therefore their processing requirements will be high as well. The larger the size of the interface, greater will be the processing load and requires more battery power. The new age devices will support 3D and will place an extra burden on the processor. Advanced features such as voice recognition, fingerprint support, retina scanning and facial verification will also demand extra processing power. This together will increase the cost implications for the interface.

What UX designers can do

User Experience experts dig deeper into the way communication between a device and user happens. They need to keep the below things in mind to help interface communicate better and let a user perform the required action without telling them exactly what to do.

KEEP IT SIMPLE

UX designers should embrace a lot of basic gestures like tapping or swiping to make users feel comfortable with the interaction. Using the most common interactions has a low cognitive load and will be easy to use. The simple interface will be quick to learn as it requires less effort and comes naturally to users.

EVERYDAY GESTURES

While gestures have to be made less complicated, they should not be confused with the ones we use without thinking. This can lead to unintentional interactions with a device.

REUSE

Interactions that reuse existing skills of the users are effective. Users make a minimum investment in learning a new skill and can quickly become experts.

PROGRESSIVE LEARNING

The interface that requires users to learn new and complex skills should have a smooth learning path where users can move from basic to advanced tasks with ease. The progressive learning curve breaks advanced tasks into subtasks that use simple skills.
