Use case writing style
To sync the writing styles we might try to put forward some key questions to answer by the use cases. This might also provide some initial structuring and helps by reflecting what aspects we would like to consider for WoT technologies.
Here are some key questions for each use case to address:
- What is the user motivation for the use case
- How does this translate to a technical Description
- What application domains are related (e.g. referring to the taxonomy)
- What interaction pattern with or btw things can be observed
- Which Aspects are not considered
Please let us know you have further questions or alternatives.
Here is a worked example:
Smart control of washing machine
What is the user motivation for the use case
Joan has a heavy load of washing to do. She decides to run it over night to take advantage of the lower power prices. She loads the clothes into the washing machine and selects the economy operation mode. She has previously set her preferences with her home automation agent that is accessible on the Web from her phone, tablet, TV or laptop.
How does this translate to a technical Description
The physical user controls on the washing machine are deliberately simple, and designed to work in conjunction with the web based home automation agent. This agent has access to Joan’s electricity supplier and as is able to track the price charged by her supplier on her electricity plan as it changes according to demand across the city. The agent runs in the cloud, but is able to communicate through the firewall with devices in Joan’s home via her home hub. This was set up automatically when she first plugged the machine in. The washing machine has a very limited embedded controller. It suffices to run the desired washing and drying cycle, and has sensors that monitor its operation and enable components that are wearing out to be detected before they fail. Joan has agreed to share this data with the manufacturer as part of the warranty agreement. In return, she gets proactive scheduling of service visits at her convenience.

Emergencies and civil disturbances
The Web of Things offers opportunities for faster reporting of accidents and for managing traffic lights and route planning for emergency vehicles. Cameras in the street, or within buildings of vehicles can make it easier to track civil disturbances, whether an individual act of violence or a demonstration that looks like getting out of control. For earthquakes and other disasters, there are opportunities for resilient communication and control systems.
- Fire, medical and police vehicles
- Information delivery in devastated areas
- Robust communication and control
- Monitoring and management of demonstrations and riots
Opportunities for offering customers personalised deals, better analytics through tracking people as they move around with stores, location based services and more. The emergence of technologies to sense what items are in your shopping cart or basket for a streamlined check out process. Simplified inventory tracking.
- Inventory management
- Perishable goods
- Anti-theft devices
- What do people spend their time looking at whilst shopping?
- How do people move around the store?
- Pushing location and context dependent offers
- Point of sales terminals
Opportunities for improved tracking of warehouses, items and shipments through tags on individual items, pallets and containers. This can range from optically scanned bar codes, to RFID tags, and smart tags that can track the location, temperature and humidity. Tagged objects can be associated with data held in the cloud. For example, where a given food item was produced and packaged, and the conditions it has experienced during its shipment, as well as its target destination. Knowing where items, pallets and containers are currently located and where it is needed makes it easier to plan shipments and optimal ways to move items about a warehouse.
- Location and environmental sensors
- Metadata relating to shipments
- Logistical planning support
- Inventory management
- Design of bespoke products
- Monitoring of system operation
- Robots, 3D printing and other technologies
- Bringing new workstations online
- Inventory management and logistics
The Web of Things brings opportunities for reducing the time from the start of design to shipping new products. It will also make it much easier to support bespoke products tailored to the specific requirements of each customer. Putting these together heralds a major shift in how products are managed. The Web of Things will also make it practical to optimise maintenance through accurate measurement of how individual manufacturing tools behave under use. It should be much quicker to introduce new manufacturing tools into a production chain, and to move work items from one station to another. The Web of Things will help with improvements to logistics and inventory control. Better information on how products are used in practice will be fed into improvements in the design of the next generation of products.

Construction and building automation
The Web of Things has opportunities both during construction and during the lifetime of buildings. During construction sensors can provide detailed information as to the conditions within the building site, as well as for the logistics involved in large projects. During the lifetime of a building, sensors can detect stresses in the fabric of the building, and help with emergencies by sensing fire and smoke, as well as the presence of people and guiding them to safety. Lighting, heating, ventilation and air conditioning systems can be optimised based upon sensing the conditions throughout the building and comparing this to which rooms are currently occupied.
