Goal Orientated System

23:30 § Leave a comment

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 answer is a system driven by a user’s goal – where the system generates the strategy.

 

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.

 

If the design objectives are laid out in a systematic way it is possible to translate them into a series of sequential steps. Therefore they are programmable in terms of computation for a Goal Orientated System.

The ULife South Korea plans to spend $25 billion on New Songdo, the world’s largest “ubiquitous city,” with computers linking home life and life on its streets. Construction, 40 miles from Seoul, is to be done in 2014.

Ambient Control through Cognitive Data

The Emotiv headset allows users the ability to wirelessly control objects through expression, emotion and cognitive data.Based on the EEG technology, emotiv has transformed the cognitive control patterns into a wearable remote control. This headset allows for control of real-time data which can directly a UI or environment. For example, your mood state could drive the meta-data relationships in a user interface to show you only particular images from your Flickr account or directly affect the physical geometry of the user’s seat as they read a book.

Gesture Control Systems

Gesture control systems are one of the many systems being developed to control interfaces. Their success depends on the input of information which is sometimes uncontrollable as there are variants in how users interact. The trick for over coming this is to encourage a meta-data language to which we will all eventually become used to and therefore use in a similar way. Gesture controlled interfaces are significant to architecture in that it allows a user the ability to directly control objects  from a distance and that they are able to control their environment from where they are standing – the system can be place around a user.

Intelligent Ambience and Building Atomisation Systems

23:30 § Leave a comment

There are two distinct methods of controlling the environmental mediums of a built environment. Preset atomisation was introduced almost 20 years ago, and although advances in technology have made Building Automated Systems more efficient, the principles remain the same. However in recent years, intelligent systems have been introduced that with the use of sensors and real time monitoring system, can allow environments to be appropriate altered without the need for administration. However, often a combination of the two systems can work in synchrony, allowing for a smart environment that can be controlled by the occupant if so wished.

  • Atomisation

Preset automation designates an emerging practice of increased automation of appliances and features, facilitated through a centralized network. Building Automation can control lighting, doors and windows, Heating, Ventilation and Air Conditioning, and security, surveillance systems and more ethereal qualities such as sound and smell. Building atomisation are all means that are used to integrate the electrical controlled equipment in the built environment, with the purpose to increase the level of comfort, security and energy management in that environment.

An automated control system controls the environmental mediums through a centralised network, a certain number of parameters of presets exist within the system allowing personal preferences to be set via a variety of touch points. These touch points communicated, via telephone line, wireless transmission or the internet, to provide control and monitoring via a Smart Phone or Web browser. These touch points allow users the ability to remotely toggle power to individual rooms, therefore control the ambience in that space.

In general, a Demotic System integrates and connects all electrical devices in a building with each other. Therefore in the programming of options, the fact that all the electronically controlled devices are controlled through one system means that there can be programs that control all of the environmental media at one time. By limiting the amount of options available to users, it makes the system simple to use to all involved.

  • Intelligent Ambience

Environments enriched with sensors, actuators and processing units have been increasingly integrated into the fabric of modern buildings. Often in office buildings, sensors are used to detect activity in the building, allowing for the adaption of environmental medium to required levels.

One typical example is to turn the lights in a space on for a half hour since the last motion was sensed. In being smart, these systems also have to demonstrate themselves to be sensible. Being sensible demands a system that is emphatic to its occupants. It must have the capability to react to the users moods and adapt to the prevailing situation by understanding its user and adapting accordingly.

In combination, building atomisation and ambient intelligence can be sensible whilst not over powering – the user/or administrator still have the authority. There are many different parameters as an input to resolute an ambient output. Smart systems enable programming of these parameters to create truly intelligent and responsive environments. Below are the possible input parameters that the computer can draw real-time data from in order to resolute a programmed outcome.

Sensed Data:

  • Chronological time – Chronological time is a specific time of day as pre-set timers use.
  • Astronomical time – Astronomical times includes sunrise, sunset, a specific day of the week or days in a month or year
  • Room Temperature – Based on activity sensed and in door and outdoor temperature readings
  • Room occupancy and Motion Detection – Room occupancy might be determined with motion detectors or RFID tags, and is part of security and energy conservation programs.
  • Presence of daylight – Artificial lighting energy use can be reduced by automatically dimming and/or switching electric lights in response to the level of day lighting
  • Program logic – Preset activity profiles, acitivitation specified levels of lighting, heating, purification, music and smell levels.
  • Alarms – Alarm conditions can include doors opening and motion detected in a protected area which could deactivate lighting and computer systems if activated.
  • Biological and Psychological Data – Via sensing bodily data, environments can respond to ensure a harmonised environment.

Extension of Human Activity

Ubiquitous revolution was foreseen by Mark Weiser (1991) who predicted: ‘In the 21st century the technology revolution will move into the everyday, the small and the invisible … The most profound technologies are those that disappear. They weave themselves into the fabric of everyday life until they are indistinguishable from it.’

Mark Weiser 1991, The Computer for the 21st Century

The goal of ambient intelligence is to make it possible for users to interact naturally with their environment. For environments to be truly intelligent systems they are being developed to learn needs and preferences of the occupants, diagnose situations and then react to them in a context specific way.

‘A digital environment that proactively, but sensibly, supports people in their daily lives’

Augusto Boal 2007, A Digital Revolution


This requires the system to be sensitive, achieved through the ability to classify complex human behaviour and respond to their needs with appropriate use of technology. For example, a heating system can detect is someone is present in the room, but for it to react appropriately it needs to consider a wider context, someone watching TV for example might require a warmer room than someone undertaking exercise.

The development of integrated technologies means that the home of tomorrow will be more like the home of yesterday that the home of today. The way we experience technological power is about to change. Technology and computers will no longer be seen as an intermittent step between a physical us and an outcome – but as Intelligent systems operated through interfaces that are an intuitive extension of our natural speech and movements, through touch panels, heat and weight sensors and intelligent cameras that track our eyeball movements. All striving to atomise our personal preferences with ease to provide extra convenience and help in everyday tasks.
