HCI: Ubiquitous Computing

What is context-aware computing?

• Context-aware computing is technology that can adapt to the user's context to provide relevant information or services.

• Context-aware computing is technology that focuses on historical data only.

• Context-aware computing is a type of virtual reality technology.

• Context-aware computing is a method of predicting future user behavior.

Give an example of wearable technology.

• Smartwatch

• Wireless earbuds

• Virtual reality headset

• Fitness tracker

Explain the concept of Internet of Things (IoT).

• Internet of Things (IoT) refers to a new type of dance craze

• Internet of Things (IoT) is the network of physical devices, vehicles, home appliances, and other items embedded with sensors, software, and connectivity that enables them to connect and exchange data.

• Internet of Things (IoT) is a popular video game console

• Internet of Things (IoT) is a type of exotic fruit found in tropical regions

How does augmented reality (AR) enhance user experience?

• AR enhances user experience by overlaying digital information onto the real world, providing interactive and immersive experiences.

• AR enhances user experience by limiting user interaction and engagement.

• AR enhances user experience by displaying blurry and distorted digital information.

• AR enhances user experience by removing real-world elements, making it less engaging.

What is gesture recognition and how is it used in HCI?

• Gesture recognition is the ability of a computer to recognize spoken words.

• Gesture recognition is the ability of a computer to understand and interpret human gestures via mathematical algorithms. In HCI, it is used to allow users to interact with devices using hand movements, body gestures, or facial expressions.

• Gesture recognition is used in HCI to control devices using eye movements.

• Gesture recognition involves interpreting body language in HCI.

Provide an example of a location-based service.

• Google Maps

• Waze

• Netflix

• Apple Maps

Differentiate between alternate reality and virtual reality.

• Alternate reality is a form of augmented reality, while virtual reality is a form of mixed reality.

• Alternate reality is a type of video game, while virtual reality is a type of movie.

• Alternate reality is a physical location, while virtual reality is a mental state.

• Alternate reality is a parallel universe, while virtual reality is a computer-generated simulation.

How does wearable technology contribute to ubiquitous computing?

• Wearable technology allows for continuous access to computing resources, facilitating ubiquitous computing.

• Wearable technology enhances traditional computing methods

• Wearable technology has no impact on ubiquitous computing

• Wearable technology restricts access to computing resources

Discuss the importance of context-aware computing in HCI.

• Context-aware computing only focuses on static user experiences

• Context-aware computing is irrelevant in HCI

• Context-aware computing is important in HCI for personalizing user experiences based on changing contexts.

• Context-aware computing does not impact user interactions

Explain the role of IoT in creating a connected environment.

• IoT has no impact on creating a connected environment

• IoT only works with one type of device in a connected environment

• IoT plays a crucial role in establishing a connected environment by facilitating communication and data exchange between various devices and systems.

• IoT is only used for entertainment purposes in a connected environment
