What is Touchless Technology?

Before getting into touchless experience in mobile devices, you should know what touchless technology is. Touchless technology implies that you can command or operate any device without needing physical contact. The only task that involves your physical contact is its setup. After that, you can use your device without needing physical contact.

Design Principles of Touchless Interface

Touchless UI Technology is a different and developing concept from the existing technology. So designers can use existing concepts but alter them to accommodate the new style of interaction. Below are the four basic ideas to consider while designing the touchless UI.

Should be Easy to Understand

To avoid having to learn a specific gesture language, try to use sign language or gestures from everyday life to carry out functions. Analyze how consumers naturally accomplish tasks and include these movements into your UI.

Should be Easy to Access

Gesture-based UI should be designed in a way that it should be accessible for people with disabilities. It is important to ensure that your design supports the use of assistive technology. Example: Samsung S pen.

Should be Comfortable

If the UI is uncomfortable or repetitive there is a high chance of users will abandon the application. Limit physical movement to a minimum as it can get annoying for the users.

Touchless Technology in Mobile Application Development

As we all know, businesses that fail to keep up with market trends are at high risk of losing their competitive edge. Adopting touchless technologies and transforming current solutions into a rich, seamless user experience is an accelerated trend in the market. Touchless technologies are changing the way users interact with their devices. Some of the touchless technology options that can be beneficial in mobile application development are as follows

NFC enabled Signage 

(NFC) is a communication technology that enables communication between two devices.  An “NFC tag” is a microchip carrying recorded information that is used to communicate between devices. Customers hold their phones up to NFC-capable signage, which automatically connects with equipped devices or a contactless reader within a specified range, allowing them to complete an activity, such as providing payment confirmation or a virtual boarding ticket, through the use of a mobile app. Among the uses for NFC-enabled signage technologies are

• Contactless payment
• Attendance tracking
• Authentication apps
• Public transportation

Gesture Recognition

Another form of touchless technology is gesture recognition, which can be implemented in mobile app development. Gesture technology uses motion detection sensors to recognize and analyze movements that interact with a software system. For example, hand recognition technology allows you to operate screens without the need for physical contact with the display surface. This technology can be beneficial for 

• Automotive, 
• Gesture-based gaming control, 
• Gesture-based home appliances, 
• Electronics
• Home Automation.

Biometric Authentication

Biometric authentication is a security process that measures the physical characteristics of a person to verify the person’s identity (for example; face and palm recognition). Facial recognition is the most common biometric authentication which provides the best performance in many environments. Benefits of facial recognition in mobile phone includes:

• It does not require any physical button to function, thus it is very fast and convenient.
• Advanced facial recognition technology analyzes the face in a three-dimensional format. It includes dimensions of the face, the width of the nose and eyes.
• Face recognition technology can function properly with the built-in camera on your phone.

QR Code/Barcodes Scan

A Quick Response is an open-source technology easy for mobile applications to scan. A QR code is a version of a barcode, that can provide instant access to information. QR codes can direct users to download mobile apps or visit a website. The QR codes can  be used in

• Touchless menu app
• Touchless feedback forms
• Product tracking
• Content linking

How Touchless UI Enhances UX

Increased Convenience and Efficiency

One of the most obvious advantages of touchless UI is improved convenience and efficiency. You can do activities faster and with less effort if you don’t have to physically touch your gadget. This is especially handy for tasks that require several stages, such as sending a text message or email.

Reduced Distraction by Design

Touchless UI reduces the distraction caused by design, thus it enhances the user experience. For example, instead of touching the phone with your hand, you will be able to wave your hand in the air to complete the task.

Easier Accessibility for All

Touchless Technology also comes with increased accessibility benefits as anyone can use them regardless of their physical abilities. The touch screen requires physical touch to complete the task, whereas touchless UI can provide software to function without any physical contact. This makes touchless UI accessible to anyone.

Greater Flexibility

Touchless UI also offers more versatility in terms of user engagement. You don’t have to stay in one place when using your phone. You can move around while still controlling the cell phone. 

Conclusion

Though it is difficult to meet customers’ expectations for touchless UI, app developers must first understand the consumer’s needs. This is because touchless UI is a growing technology that has the potential to transform the way consumers interact with their mobile devices. Investing in touchless UI technology to improve user experience has thus become a component of the digital transformation plan. To read more technical blogs frequently Visit our website.
