How AI and IoT Are Transforming Smart Glass Technology

Evolution of Smart Glass: From Manual Control to Intelligent Systems

Early smart glass systems used simple control methods, including wall-mounted buttons/switches, remote controls, or set timers. These systems allowed for on-demand privacy or shading; however, they were largely static and required human input.

There are several disadvantages to non-connected smart glass systems.

• No sensor information about current weather or occupancy levels
• High energy waste through constant (static) use of predetermined settings
• Scale limitations in large commercial spaces

The development of smart glass with an intelligence layer has been initiated by connecting smart glass to sensor systems, networks, and other building technologies. Today's AI and IoT-enabled smart glasses are based on data and are adaptable. The smart glass can operate automatically in response to both environmental factors and user behavior without requiring human intervention.

Role of IoT in Smart Glass Technology

Sensors Powering Smart Glass Decisions

IoT is the backbone of smart glass technology, which will allow smart glass to "know" what its surroundings are by using sensors. The most common sensors for smart glass are:

• Lux light sensors: Measuring daylight intensity to adjust glare and brightness
• Temperature and thermal sensors: To detect both internal and external heat levels
• Motion/occupancy sensors: To determine if a space has people occupying it
• Sensors for weather/environment: To measure sunlight, clouds, etc.

The above sensors provide real-time information so smart glass can react in a very precise manner.

Connectivity and Communication Protocols

Smart glass that is enabled by IoT depends upon a solid communications standard like Wi-Fi, Zigbee, Z-wave, BACnet and/or KNX. Each of these provides the smart glass a way to be integrated into other systems of a building.

Smart Glass Control Architectures can be composed of:

• Edge devices that are able to provide faster responses because they do the processing on the device itself, versus sending the request to a cloud.
• Cloud-based platforms that are used to provide a central point for analytics and optimizations.

The integration of smart glass with a Building Management System (BMS) allows the smart glass to work cooperatively with the HVAC, lighting and security systems in the building.

Real-Time Monitoring and Remote Control

IoT (Internet of Things) technology enables managers to access a central dashboard for viewing glass performance throughout an entire building. With this capability, users are able to manage smart glass using their mobile device, via a voice assistant, or by using an API that connects to a larger smart building ecosystem.

How AI Enhances Smart Glass Functionality

Predictive Light and Heat Management

AI does one better than just taking sensor data and creating an ability to identify patterns and make predictions for the future. Unlike reacting to changes in environmental conditions, smart glass that is driven by AI can adjust its tint level prior to changes in the environment.

The key features of smart glass with AI are:

• Learn about the preferences of occupants, from experience and history
• Predict sunlight based upon seasonal patterns and the time of day
• Adjust for optimal daylight automatically – no user input required

Energy Optimization Through Machine Learning

Smart glass can be paired with HVAC and lighting systems through machine learning algorithms. Smart glass balances artificial light, heating gain and cooling demand through the use of AI to continually improve a building's energy efficiency by reducing peak energy loads.

The system will become smarter over time, identifying inefficiencies in the system and continually refining strategies that help achieve the greatest amount of energy savings.

Computer Vision and Context Awareness

Smart Glass with Privacy Safe Computer Vision Technology Can Use Privacy-Safe Artificial Intelligence (AI) to Understand Space Usage. Smart Glass does not store identifiable personal data for this purpose. The technology is able to:

• Determine the level of occupancy
• Automatically adjust the level of privacy, depending upon what is occurring in the room
• Determine common usage patterns in a Meeting Room, Ward, or Living Area.

AI + IoT Use Cases for Smart Glass

Smart Offices and Commercial Buildings

Smart offices and commercial buildings are among the most popular applications of AI-based smart glass. Smart glass can help increase office worker productivity through a variety of ways, such as minimizing glare, maintaining the right amount of daylight, and instantly changing privacy levels during a meeting. With the automated functionality of smart glass, an office worker can enjoy a workspace that is always comfortable and free of distractions.

Healthcare Facilities

The use of smart glass in healthcare facilities has been shown to have multiple benefits. Smart glass can make patients feel much better when they are able to view natural light in their hospital or clinic room. In addition, smart glass can assist healthcare workers in reducing the risk of infection through less frequent contact with window treatments. Finally, smart glass allows healthcare workers to quickly and easily maintain privacy and confidentiality in patient rooms.

Residential Smart Homes

Smart glass is also being utilized in residential smart homes across North America. Homeowners can customize the amount of daylight entering their home and the level of privacy available in each room using smart glass. Voice command capabilities allow homeowners to access all of the functionality of their smart glass through their preferred smart speaker or virtual assistant. Energy consumption is significantly reduced through the automation of lighting in each room through smart glass.

Automotive and Transportation

Finally, AI-enabled smart glass is increasingly being used on the windows and sunroofs of vehicles to enhance the comfort of drivers. Additionally, smart glass reduces glare and assists in the development of autonomous vehicles.

Benefits of AI- and IoT-Enabled Smart Glass

• A lower carbon footprint due to reduced energy usage
• Occupants will be more comfortable and have better health as well as well-being
• The smart glass can lead to lower total operating expenses for the building over time
• Sustainability and Environmental Social Governance (ESG) performance will improve
• The smart glass provides actionable data based on how the building behaves

Challenges and Limitations

Data Privacy and Security Concerns

Data privacy, security, sensor data governance, and AI transparency have become major concerns for companies and hospitals as they implement smart building technologies, particularly if their applications of this technology include integration of an AI system or other advanced digital technology.

Integration Complexity

When developing a smart glass product that is integrated into older buildings, it can be difficult to find ways to make the new products work well with the old legacy systems.

Cost and Infrastructure Requirements

Although the cost of smart glass has decreased, significant investments will need to be made in hardware and software for the AI to function properly as well as regular maintenance to ensure the ROI is achieved in the medium to long term.

Market Trends Driving Adoption

Smart City Initiatives are creating a tremendous amount of interest in this area, as well as increasing ESG (Environmental Social Governance) compliance, and decreasing the cost of sensors and artificial intelligence that will be necessary to create an AI-driven smart glass system. In addition, there is also an increasing trend of using Digital Twins for building simulations and optimizations which will lead to AI Driven Smart Glass Systems being used in more buildings.

What the Future Holds for AI-Driven Smart Glass

The future of smart glass will be fully autonomous, self learning glass systems, integrated into urban infrastructure. The emerging areas of research on smart glass includes emotion aware environments, biometric-responsive environments, and fully adaptive building envelope which can adapt and respond in real-time to changing human and environmental conditions.

Who Should Adopt AI-Enabled Smart Glass Today?

Smart glass technology has many potential uses, but it's best suited to large-scale commercial and residential environments that can fully utilize its capabilities, such as:

• Large corporate office spaces or campus settings
