Resources Industries: Industrial

The first IoT devices were popular because of their novelty. As the of available IoT devices grows, standards are getting higher. Success in IoT device manufacturing depends on designs that capitalize on these seven trends.

1 – Connectivity

As more types of devices join the IoT, there’s an increased need for them to all work together. Users expect data sharing and interconnectivity across networks. Real-time communication between devices and systems is ideal. When an embedded GUI sends and receives data with the cloud on a schedule, users expect to know how current the information is.

In either case, communication across networks must be seamless. That means embedded GUI developers must understand various protocols and technologies such as Wi-Fi, Bluetooth and Zigbee. Interfaces with broad compatibility will win market share.

2 – Multi-Modal UI

Many IoT devices still need a physical user interface. For example, a smart refrigerator or smart lamp still must work when the Wi-Fi goes down. The following features and capabilities help embedded GUI teams balance UX, aesthetics and battery life:

• Voice search and voice control for intuitive, hands-free operation
• Touch-based interfaces for precise control over scrolling, typing or drafting
• Haptic feedback to provide tactile cues and alerts

Including multiple modalities allows users to control the device according to their needs. Alternative ways of input and output increase accessibility, decrease product failures and empower efficient user experiences.

3 – Simplicity

Users aren’t used to navigating steep learning curves when buying new refrigerators, watches or doorbells. Devices that offer visual representations of only the essential information are simple to use and understand. Clear, concise language and intuitive UI design make a device easy to use effectively without additional training.

Testing and validation ensure that connected GUIs work as intended and meet user needs. Thorough testing also helps squash any bugs or issues that they arise. Altia’s model-based   development enables teams to test with users early and confirm that the GUI is easy to use.

4 – Performance

Even with efficient IoT data processing, too much information can hurt the scalability of the UI. Users don’t want to wait for interfaces to load and respond, so the GUI must be responsive and fast. Efficient data processing also conserves battery and processing power.

Presenting information in graphs or dashboards can help draw simple meaning from massive amounts of data. When showing many events or messages is unavoidable, pagination allows loading the data in manageable parts.

The best devices have GUIs that are optimized for performance and efficiency. For example, the Tandem Diabetes Care T-Slim insulin pump can run for a week on a small rechargeable battery.

5 – Security

As IoT adoption expands, so does the attack surface. Security vulnerability has become one of the most critical challenges for IoT device manufacturers. Security features like machine-to-machine authentication, biometric logins and AI-powered security practices can help.

Awareness and training go a long way, too, but users don’t want to carry the burden of protecting themselves alone. Embedded GUIs should be designed with security in mind, as cybersecurity concerns can destroy a product’s appeal.

Recognizing the Threats

Unauthorized access or manipulation can cause significant harm to the IoT infrastructure and users. Successful hacks compromise user privacy, safety and business operations. Secure GUI design can prevent vulnerabilities such as buffer overflows, injection attacks and other exploits that attackers can use to gain access to the system.

A secure GUI design goes beyond preventing unauthorized access to the system’s hardware, firmware and software. It must also include intrusion detection and prevention mechanisms to ensure appropriate responses to suspicious activities or attacks. Avoiding security incidents spurs user confidence in IoT systems and drives widespread adoption.

Privacy and Security Solutions IoT Devices

Trust is non-negotiable for connected devices, which means embedded GUI teams must steer clear of common IoT security challenges. IoT device manufacturers can build trust with any or all of the following:

• Automatic security updates
• Customizable privacy settings
• Transparency in data collection
• Two-factor authentication (2FA)
• Secure communication protocols
• Enforcement of strong passwords
• Encryption of sensitive information

Addressing security and privacy concerns is vital during the GUI design phase. Embedded GUI teams should also commit to ongoing efforts to keep the device’s software and firmware up to date, preventing security breaches.

6 – Personalization

Few UX design trends among IoT offerings are more pressing than personalization. Sensors, beacons and adaptable technology make it possible to deliver customized experiences in industries ranging from retail and automotive to healthcare and edutech.

Modern customers expect products to meet individualized needs and personal preferences. This also ushers in a golden age for marketers who want to deliver more impactful experiences. Customizable settings and functions boost satisfaction, loyalty and adoption.

Personalization of features also benefits data collection. Product teams can see how users interact with devices, which guides future enhancements. For now, personalization is considered a premium feature. Soon it will be the cost of admission into the IoT market.

7 – Incorporation of artificial intelligence and machine learning

Collecting data used to be the hard part. Now the challenge is in making sense of mountains of data. Machine learning and artificial intelligence make big data more useful for IoT devices. Advanced analytics will empower everything from preventative security enhancements to predictive maintenance, thus reducing downtime, maintenance costs and energy consumption. ML and AI also serve other UI trends for IoT devices, such as advanced security features, voice control and customization.
