Smart technologies can be used to illuminate the night. Street light intensity and coverage can both be controlled, depending on physical parameters, such as the time of the day, or weather conditions.
The amount of pedestrians in the street or their activities could be further parameters used by algorithms for these type of applications.
Discuss the technologies that ambient intelligence uses in this specific scenario.
With a focus on privacy, discuss how traffic data from WiFi communication through smartphones can be used in this scenario.
Southend Council in England is considering whether to use Pepper, a humanoid robot, to assist some elderly residents that live in care homes. These elderly residents suffer from memory loss and would rely on Pepper to direct them them to and from the local shops. Pepper uses ambient intelligence and is connected to the Internet of Things (IoT).
Explain why Southend Council may have concerns about introducing Pepper for this purpose.
A video streaming service, StreamPro, uses various techniques to help users search and find multimedia content, such as movies and music.
Outline two methods StreamPro might use to improve multimedia searchability.
Explain one challenge StreamPro might face when implementing searches for non-text-based content, such as images or video.

The development of technologies that underpin the World Wide Web has led to the growth of ambient intelligence and collective intelligence.
Identify two features of ambient intelligence.
Outline two reasons why there needs to be a balance between expressivity and usability on the semantic web.
Explain why a user can still navigate from one web page to another web page in the same amount of time as previously, even though the number of web pages is significantly larger.
Describe how a web graph can be used to represent the connectivity of the World Wide Web.
Evaluate the role of collective intelligence in the advancement of human knowledge.
