5. Home Gateway Initiative Home Gateway Initiative (HGI) – Partner Type 2 – Initial role was to specify requirements and test plans for Home Gateways (HGs) that support Quality of Service and the rollout of triple-play, broadband services. The scope has been expanded to cover the entire spectrum of requirements for devices and service support in the digital home – Use Cases for Media Gateway and Home Energy Management Service Source – http://www.homegatewayinitiative.org/documents/Current_HGI_Pu blications.asp http://www.homegatewayinitiative.org/documents/Current_HGI_Pu blications.asp

6. HGI – MG Use Cases Use Cases for a Media Gateway – Seamless interaction between the growing variety of video and network enabled retail devices in the home – Involve the Media Gateway working in conjunction with a Cloud service – Some include media consumption outside the home to support customers “on-the- go”

7. HGI – MG Use Cases “Follow-me” Use Case – Enables users to suspend the current content stream and resume it later on any of their devices, either within or beyond the home – The MG can control which content is allowed to be streamed outside the home depending on the nature of the service and license conditions Source: HGI-BR040 : Use Cases and Business Requirements for a Media Gateway (MG)

8. HGI – HEM Use Cases HEM Use Cases – Coming principally from Energy@home and BeyWatch projects Use Case: Alarms – The HG can relay or activate alarms on a variety of devices – The user can set alarm priorities Use Case: Home Domain Overload Management – Individual appliances have their behavior regulated based upon home power availability – Aim is to encourage the use of appliances when there is enough power in order to avoid overloading Use Case: Optimize Energy Cost – The system performs actions in order to reduce and optimize the energy cost – The optimization of energy cost applies in the case of a multi-tariff contract – Configuration of a monthly cost limit is also supported

9. HGI – HEM Use Cases Use Case: Alarms – Notification of potential Home Domain Overload The customer is informed promptly when the overall power drawn is near the maximum available power, hence indicating a potential Home Domain Overload. The notification could be done via acoustic alarms and/or SMS. The customer can also access the alarm history – Notification if a user configured limit is reached The customer is informed promptly when the overall power drawn exceeds a limit which has been configured by the user. The notification could be done as per 3.1. The customer can also access the alarm history – Black out In case of energy blackout the Home Gateway, if equipped with an UPS, is able to guarantee the correct activity for a minimum time (< 60 s). It can alert the customer about the event with an alarm (e.g. SMS, phone call) – Abnormal appliance consumption The customer is informed promptly in the case of abnormal appliance consumption (e.g.: possibly indicating a fridge with a door left open)

10. HGI – HEM Use Cases Use Case: Home Domain Overload Management – Home Domain Overload management for smart and non-smart appliances The system can optimize the use of power in order to avoid Home Domain Overload The customer can define/modify the load shedding priorities and strategies in the case of a Home Domain Overload. This can be applied to smart and non-smart appliances (via Smart Plugs). A central unit located inside the house will implement the coordination logic. An alarm (e.g. acoustic) can be generated to notify the customer of any critical condition In order to simplify the process, default configurations could be considered – Request confirmation to start if the available power (in the home) is not sufficient to run a Smart Appliance The system may require explicit confirmation from the customer if the use of a Smart Appliance may lead to power overload The system checks if the total available power in the home is sufficient to run the Smart Appliance, depending on its power profile estimation, on other Smart Appliances estimated power profile and on the current total consumption The customer is notified that there is not enough available power to run the Smart Appliance and the customer can make the final decision what to do

11. HGI – HEM Use Cases Use Case: Optimize Energy Cost (1/2) – Multi-tariff energy use optimization in the case of both smart and non-smart appliances The system provides an optimization of appliance usage in order to optimize energy cost according to the variable energy tariffs. This Use Case is meaningful for all those appliances which are activated by the customer and perform a specific operating cycle, such as a washing machine or dishwasher. The most important exception is the fridge, which operates continuously The customer can define/modify the house rules for energy cost optimization in the case of single or multiple appliances. For any appliance, the customer can set parameters like the operational time interval allowed for the device (e.g. from 6:00 to 24:00). Smart Plugs could be used to manage the operational time interval for non-smart appliances (e.g. a boiler). In order to simplify the process, default configurations could be considered

12. HGI – HEM Use Cases Use Case: Optimize Energy Cost (2/2) – Automatic time shifting of some phases or functions of the Smart Appliance for favorable economic conditions This Use Case foresees Smart Appliances' capability to delay some of their specific functions (either activated by the customer or automatically within the cycle) according to current tariff and energy cost The coordination between the different entities in the house and their needs in terms of power consumption will allow consideration of the overall power consumption forecast and thus better optimize the energy costs and prevent overloads – Configure cost limit Users may configure their HEM system to limit monthly cost. The system offers a simple way to configure these limits with a clear and intuitive interface. The HEM system can suggest the recommended consumption of each application to achieve the configured cost limit. This would need to be in user friendly terms, e.g. number of washing machine usages

13. Raising the Floor Consortium – Focuses on developing Global Public Inclusive Infrastructure (GPII) – GPII ensures that everyone who faces accessibility barriers due to disability, literacy, digital literacy, or aging, regardless of economic resources, can access and use Internet technology to access information, communities, things and services for education, employment, daily living, civic participation, health, and safety – Provides use cases on assistive technology, auto-personalization and configuration Source – http://wiki.gpii.net/w/Use_Cases_and_Implementations http://wiki.gpii.net/w/Use_Cases_and_Implementations

14. GPII – Smart House Use Cases Smart Houses in a Foreign Environment – People that need assistive technology usually have it set up at home – Applying the same configuration at a foreign place is time-consuming and wearisome – Easy application of personal settings in various home environments (in parents’ house, at a friend, in a hotel, etc.) is necessary Smart House (home appliances); Multiple Preference Sets – People in need of assistive technology usually live in a place together with someone else – In some cases, the preferences for appliances and devices, set by one might not be appropriate for other – Support for multiple preference sets in one environment is necessary

15. GPII – Smart House Use Cases Smart Houses in a Foreign Environment (1/2) – Helen is a 25 years old student. She lives alone and is worried about the safety of her home, so she has a security system installed. Helen is heavily dependent on non-visual feedback from any devices she is using (she completely lost her sight due to an accident). The security system requires a numeric code to be entered to be turned on or off. It has a feature of pronouncing the number corresponding to the button pressed. The A/C system is controlled by a remote control that vibrates in different patterns as air conditioning is turned on/off or the temperature is changed. Helen often visits her parents’ home where she needs the same settings to feel comfortable. They want these settings to be applied only when she visits them, so they have installed an RFID card reader at the entrance

16. GPII – Smart House Use Cases Smart Houses in a Foreign Environment (2/2) – Ivan Petrov is 23 years old Bulgarian. He is sent to Germany for experimental treatment procedures. During his stay there he is been accommodated in modern Hotel near a clinic. Ivan doesn't understand German and he has difficulties with his mobility and motor skills (Down Syndrome). The Hotel is equipped with some of the latest technology advancements in order to accept patients with similar conditions. The multimedia system (TV, Radio, Stereo), phone, etc. have ability to personalize their button mapping and language in order to help the patient during their stay. Ivan uses similar home appliances in his home back in Bulgaria, so he has his personal settings on his mobile phone and can transfer them to the devices in the hotel room using NFC

17. GPII – Smart House Use Cases Smart House (home appliances); Multiple Preference Sets – Albena is 40-year old user. She wears a hearing aid although it doesn’t restore her hearing completely. She needs a higher volume when using the home multimedia system (TV, DVD player, Home Theatre, etc.) or for calls on the phone (she is hearing impaired). Also she prefers other types of interaction to avoid relying only on the sound. The members of her family have normal hearing, and it is not possible to configure the volume settings or the non-sound indicators once and for all, as there is no specific setting that would be acceptable for all members – When she is alone at home, Albena configures the home phone with her preferred settings by identifying into the system (using her USB identifier, NFC ring or some other way). Once she logs in, the phone settings automatically changes - the volume during call sets up to her preference level, and visual indicators for incoming calls turn on – When she wants to use the Multimedia system (watching TV or using the Home Theatre), she logs into the system in the same way. Once she is identified, the volume of the system sets up to her preferred level and subtitles are turned on – Edge case: as the maximum volume level of the systems is harmful for her family, a priority of user preferences is set: when other member of the family identifies with the Multimedia system (Albena still logged in), the volume sets to the normal level, but the subtitles and other visual indicators remain

18. IETF ACE WG IETF Authentication and Authorization for Constrained Environments (ACE) Working Group – Focuses on authentication and authorization for constrained environments – Provides use cases involving constrained devices with certain authorization problems to be solved Source – https://tools.ietf.org/wg/ace/draft-ietf-ace-usecases/ https://tools.ietf.org/wg/ace/draft-ietf-ace-usecases/

19. ACE – Home Automation Use Cases Controlling the Smart Home Infrastructure – Configuration must be easy and require little effort – Administration effort needs to be kept at a minimum – The owners of the automated home want to prevent unauthorized entities from being able to deduce behavioral profiles from devices in the home network Seamless Authorization – Home Owners want their devices to seamlessly (and in some cases even unnoticeably) fulfill their purpose – Usability is important since the necessary authorization related tasks in the lifecycle of the device (commissioning, operation, maintenance and decommissioning) likely need to be performed by the home owners who in most cases have little knowledge of security

20. ACE – Home Automation Use Cases Remotely Letting in a Visitor – The home owner wants to grant temporary access permissions to a party – The home owner wants to spontaneously change the home’s access control policies – The home owner wants to be able to configure authorization policies remotely – The home owner wants to spontaneously provision authorization means to visitors – Authorized Users want to be able to obtain access with little effort

21. ACE – Home Automation Use Cases Controlling the Smart Home Infrastructure – Alice and her husband Bob own a flat which is equipped with home automation devices such as HVAC and shutter control, and they have a motion sensor in the corridor which controls the light bulbs there – Alice and Bob can control the shutters and the temperature in each room using either wall-mounted touch panels or with an internet connected device (e.g. a smartphone). Since Alice and Bob both have a full-time job, they want to be able to change settings remotely, e.g. turn up the heating on a cold day if they will be home earlier than expected – The couple does not want people in radio range of their devices, e.g. their neighbors, to be able to control them without authorization. Moreover, they don’t want burglars to be able to deduce behavioral patterns from eavesdropping on the network

22. ACE – Home Automation Use Cases Seamless Authorization – Alice buys a new light bulb for the corridor and integrates it into the home network, i.e. makes resources known to other devices in the network. Alice makes sure that the new light bulb and her other devices in the network get to know the authorization policies for the new device. Bob is not at home, but Alice wants him to be able to control the new device with his devices (e.g. his smartphone) without the need for additional administration effort. She provides the necessary configurations for that

23. ACE – Home Automation Use Cases Remotely Letting in a Visitor – Alice and Bob have equipped their home with automated connected doorlocks and an alarm system at the door and the windows. The couple can control this system remotely – Alice and Bob have invited Alice’s parents over for dinner, but are stuck in traffic and can not arrive in time, while Alice’s parents who use the subway will arrive punctually. Alice calls her parents and offers to let them in remotely, so they can make themselves comfortable while waiting. Then Alice sets temporary permissions that allow them to open the door, and shut down the alarm. She wants these permissions to be only valid for the evening since she does not like it if her parents are able to enter the house as they see fit – When Alice’s parents arrive at Alice’s and Bob’s home, they use their smartphone to communicate with the door-lock and alarm system
