O que são espaços inteligentes?

Bridging our conceptual understanding of smart space and the physical technology that brings it to life, there is a widely accepted framework that divides smart spaces into three different environments interacting as one: a virtual computing environment, the physical environment, and the human environment.

• Virtual Computing Environment — The virtual computing environment layer allows smart device access to the internet, or private network services, that allow them to connect to other parts of the distributed systems that powers the smart space environment.
• Physical Environment — The physical environment layer is the most varied layer of smart spaces, and includes embedded sensors, microprocessors, tracking tags, and the other physical aspects of the smart space.
• Human-Environment — Devices that accompany people fill this layer, like smartphones, wearable smart devices, and internal smart devices like pacemakers. This means humans can make up smart space environments through cell towers, cell networks, and smartphones to create a virtual, physical, and human smart environment that can be thought of as a wide area smart space, think route-planning apps.

Using this multi-layered approach to smart space environments (virtual, physical, and human layers), we can categorize smart enabling technologies according to their function.

Virtual Environment Layer Technology in Smart Spaces

Connectivity and control technologies enable the virtual aspect of smart space environments. Think everything wireless, 4/5G cellular, BlueTooth, LiFi, ZigBee, etc. Once connected, AI and automation software, operating locally or in the cloud, can work through the remaining physical and human layer devices, collecting and processing data to create the 'smart' effect that brings smart spaces to life. Common virtual layer technologies include:

• Artificial Intelligence and Machine Learning
• Computer Vision
• Speech Recognition
• Blockchain
• Cloud computing / Distributed systems
• Wireless Connectivity

Physical Environment Layer Technology in Smart Spaces

Data capture is an integral aspect of smart spaces and is needed to feed information to the smart algorithms to make intelligent decisions about changing conditions. Primarily, sensor devices provide the means to fill the data pipeline within the location. But, in the example of smart factories, global data may be factored into local decisions. Technologies deployed in the physical layer include:

• Motion and proximity sensors
• Climate sensors (temperature, humidity, pressure)
• Accelerometers and gyroscopic sensors
• Optical and thermal sensors
• Gas and level sensors
• RFID tagging
• Microprocessors

Human-Environment Layer Technology in Smart Spaces

Human smart devices, like smartphones, are ideal interfaces between humans and smart spaces. But new technology is opening opportunities for developers to build for a different class of smart consumers. The following lists common human smart devices, and possible future interfaces that could change how we think about smart spaces, especially in the medical sector.

• Smartphones, tablets, watches
• Closed-loop insulin delivery systems, aka Open Artificial Pancreas System
• Ingestible sensors
• Smart inhalers
• Smart pacemakers

With these technologies and an evolving sense of interactive spaces, we're a long way from fully responsive environments—imagine Star Trek's holodeck—but today engineers are already piecing together what could be its precursors.

Since any space can be made smarter by installing sensors and processors and connecting them with intelligent software, many smart spaces have become smarter, and new applications are continually adopted. Places near us have become smarter, and so have places we may rarely have on our minds but benefit us in the background regardless.

Smart Homes — In order to make our living environments even more comfortable and efficient, smart homes enable smart spaces to connect many household devices and house systems. Many appliances are now smart, like smart refrigerators or smart ovens, but now home automation can attend to home systems that control lighting, air conditioning, entertainment, even security. It even has a name—domotics.

Smart Buildings — Smart buildings apply many features found in smart homes just at scale. Smart buildings implement smart spaces to interconnected automated building systems that monitor lighting, air conditioning, heating, security and access, parking structures, water meters, power meters, fire systems, boilers or chiller plants, elevators, and more depending on the building. An office building may be made smarter for the purposes of keeping units occupied and costs down, whereas a hospital, with stocks of pharmaceuticals and equipment, may deploy a smart RFID technology to track, secure, and replenish its inventory as needed.

Smart Factory — Smart factories are not a new thing, since many manufacturing industries were the petri dish that 'smart' technology was grown on. Now, the connected smart factory has taken on a smart space paradigm shift towards a digital supply network where many factories and suppliers are interconnected, and smaller units can make decisions based on system-wide data. Considering the extent of globalized supply chains, an automated supply chain results in an agile and efficient operation with less downtime and adaptability to new demands.

Smart Cities — Smart cities are urban areas outfitted with smart space technology for a governance purpose. Smart cities have the potential to impact tens of thousands of people with greater efficiencies. Smart initiatives are already enhancing citizen's lives. Some cities made use of smart spaces by digitizing public documents to be made available online, in order to improve their constituents' digital inclusion. Many cities also have light pole initiatives that mount and hide antennas that bring digital access to their people.
