Ubiquitous computing is in the works and so is the smart building.

From portable computing to smart devices and from calm computing to wearable computing, architecture will no longer exist as a static “frame” which surrounds activity. Instead, buildings will begin to “move” around their occupants — as if to gain a nervous system.

Networks will help Buildings be Smart

Computers are getting smaller and they are being increasingly networked. The result will be buildings that communicate with both their exterior and interior environments. Since computers will be embedded in just about everything, from environmental objects to occupant clothing, designing for this type of ubiquitous computing evolution will be both challenging and amazing.

For starters, buildings will have to protect while also …[Read Full Article]…

INFORMATION EVERYWHERE

The hospital of the “future” is just around the corner. Already, research is being done to create an “interactive hospital” (1) — also known as a ubiquitous smart space.

The first step for better hospital design is a shift in mind-set where computers need to be thought of differently — departing from the traditional “office-type” mentality.

You see, hospitals deal with all formats of information that need to be accessible anytime and anywhere within the hospital. (1) Instead of providing one computer per person, an interactive hospital would provide an array of computer embedded just about everywhere so information can travel seamlessly, wherever and whenever it is needed.

A PRO-HEALING ENVIRONMENT

As ubiquitous computing technologies come together to make medical smart spaces, it becomes possible for all kinds of medical devices to help with data and collaboration management. The first step is for hospital technologies and environments to become interactive — helping the medical team to do a better job, more quickly.

Here is a glimpse of how an interactive hospital might work: …[Read Full Article]…

The development of smart environments causes a lot of concern for both designers and skeptics. Both want to make sure that such innovations have great benefits that will greatly outweigh the costs. For this reason, it is important to question advancements as designers and engineers continue to research, test and develop smart environments.

A BRIEF DEFINITION

I recently wrote a very brief “smart environment” description as follows:

A smart environment takes the notion of interactive architecture a bit further. With the use of sensing devices and actuators it will be possible to coordinate different objects and materials in a built environment to make buildings more functional and better able meet occupant needs in real-time. One trend is to make smart environments “goal-based” (thus, occupant-centered).

Here’s another post where I describe the “goal-based” smart environment trend: Why Ubiquitous Computing should be Goal-based

If you would like to read more about smart environments, be sure to visit the Sensing Architecture Article Page to see more posts listed under the “Smart Environment” section (to the right on the page).

Also, a book that discusses ubiquitous computing is: Everyware: The Dawning Age of Ubiquitous Computing (Voices That Matter)) It describes the many pros and cons of ubiquitous computing – one of the major trends that will make “smart” buildings possible. I find this book good because it presents both sides of the emergence of “smart” designs — with insight into how we can shape such an emergence.

CRITICAL CHALLENGES + CONCERNS

In certain circles the notion of a “smart environment” can be a very hot topic. And yes, although there are many benefits to developing such smart spaces, there are numerous reasons why people get concerned when hearing about this development. The following are a few of the challenges and concerns that I have heard expressed: …[Read Full Article]…

Ubiquitous computing is giving architecture many benefits that we will continue to see embedded in our buildings. Ubiquitous computing is the wave of the future – providing us with many new architectural functions as well as challenges. For now, let’s focus on the benefits.

The following are the top seven benefits brought about by ubiquitous computing as they impact architecture and occupants in everyday life: …[Read Full Article]…

The smart environment is made up of numerous ubiquitous computing devices. They each function to sense and actuate according to a given occupant’s need. But what happens when one device contradicts the other? How can the devices cooperate so that a ubiquitous computing environment responds correctly, as a whole?

The paper Smart Environments and Self-Organizing Appliance Ensembles raises the very interesting question, “How do you control devices you do not perceive?”. An answer to this question revolves around goal oriented device cooperation. You see, the smart system cannot rely on the user to provide a step-by-step process of how each device should behave. Similarly, the designer cannot predict all combinations of how an ensemble ubiquitous computing environment needs to respond. Instead, a system may be driven by a user’s goal – where the system generates the strategy.(1)

Within a smart environment, “goal based interactions” are likely to be at its heart. How a computing device carries out a function is not what matters most to a user. It is rather the effect of ubiquitous computing devices that is key.(1) The following is a diagram as described in the paper to illustrate how such a goal oriented context-aware environment will work.

As you can see, “intention analysis” and “strategy planning” are critical to how the ubiquitous computing system will work. Both are necessary for goal based interactions.(1)

A user’s needs may be quite varied and the smart environment’s devices must cooperate with each other in unison. In addition, as users add or remove devices to their smart environment, ubiquitous computing technologies must easily allow for such user changes.(1) In the end, a goal oriented approach calls for a dynamic system, so the user’s needs are met – even as they change in real-time.

The smart environment will be able to simultaneously feed the senses so occupants can carry out a multitude of functions. With few interface techniques a user may communicate based on their intention; and therefore, their goals. Smart environments will work seamlessly to orchestrate a smart space through context aware techniques. Appliances will form an ensemble, giving rise to architectural space that yields greatest value.

Smart environments are currently being developed — such an example is the EasyLiving project at Microsoft Research. In these spaces both occupants and objects are sensed by ubiquitous computing devices embedded within the environment. So, as occupants strive to communicate with their surroundings, interface design becomes critical.

Within the smart environment there may exist a multitude of sensor types. In the EasyLiving paper entitled How a Smart Environment Can Use Perception, cameras, microphones, active badges and pressure sensing floors are all listed as sensing devices. Of course, the list goes on and on as new technology evolves; however, the main overarching goal for all devices is to develop the smart environment to detect both people and objects in “context”.(1)

This idea of sensing “context” means that a given environment can sense what goes on within it to determine an occupant’s given state over time. The smart environment reacts automatically to assist the occupant as certain objectives are targeted. Features like person recognition, person location, person activity and person expression may all be sensed by smart architecture trying to read its occupant’s needs.(1) Additionally, to help with this, objects may be sensed within a given environment as well. Again, objects are sensed in “context” – two methods are object tracking and object recognition.

So, what happens to architectural design as environments become smarter? How will the user interface design of architectural features look and feel? What will happen to interior design and architecture as ubiquitous computing becomes more widespread?

Well, for starters, occupants will begin to communicate with their environments more and more. Occupants will gesture, for example, sending signals to their surroundings. And if occupant expression, gaze and speech can direct environmental features, then architectural design will have more transient states.(1) Thus, the advent of smart architecture brings with it greater potential for a more comprehensive composition of architectural space – including targeting all of an occupant’s senses.

Already, certain new technologies are emerging – such as new objects that can help occupants communicate with their smart environment. The “XWand”, for instance, can be held in different orientations that signal the environment to take action.(1) We are headed toward environments where everyday objects will ultimately take part in the world of ubiquitous computing. Embedded devices will be everywhere and most objects will take part by integrating more subtle and sophisticated design interfaces.

Perception will be two-way — not just from occupant to architecture, but also from architecture to occupant.

Biofeedback works via the mechanisms of feedback within a system. This is when, during a process, information is given to a previous point to correct a developmental path. Feedback can be quite useful in a realm of areas, particularly when it comes to human health – as in “biofeedback”. During biofeedback, machines help patients to improve the performance of their body physiology by allowing them to train their bodies to respond to stimuli given by a special biofeedback device.(1) Thus, using feedback to optimize performance is a tool that I can see being useful when it comes to the design of smart architecture. Let me explain…

Embedded with sensors, a smart architectural environment and its many ubiquitous computing objects will have the ability to monitor occupant interactions. Such a collection of occupant information may be used to help meet a variety of human needs by detecting patterns or unhealthy behaviors. For example, smart architecture may be able to improve occupant health by making key suggestions at certain decision-making moments. Architecture would be using some principles of biofeedback to help its occupants during the course of their daily activities.

While occupants go about their daily lives, smart architecture could help occupants via its interactive features. It would work with occupants to help them engage in healthier behaviors. For example, using feedback, smart architecture could suggest healthier behavioral options to help occupants increase exercise, eat well balanced meals or improve sleep routines.

All in all, smart architecture can be used to improve people’s lives. From weight maintenance to heart health, from stress relief to stroke rehabilitation — smart architecture can make a positive difference. Just imagine being in an environment that helps you maintain, improve or rehabilitate your good health. When designed with such goals in mind, smart environments become healthy environments; however, smart architecture can benefit occupants beyond healthcare needs.

Smart architecture that utilizes feedback principles can also make huge differences involving other architectural design concerns. For example, using feedback can also make buildings more sustainable, the workplace more productive and schools better for learning. It seems that feedback can help architecture become even more functional as it gains more targeted and meaningful interactivity with its occupants.
