    Study Notes

    Unit 6: Emerging Technologies in HCI

    • Emerging technologies in the field of Human-Computer Interaction (HCI) are transforming how people interact with computers.
    • Various emerging interfaces, technologies, and concepts are shaping the future of HCI.

    Contents

    • Emerging interfaces
    • Emotional interaction
    • Persuasive technologies
    • Anthropomorphism
    • Ethical design
    • Digital forgetting
    • The future of HCI

    Emerging Interfaces

    • Brain-computer interface (BCI)
      • Uses electrodes placed in the brain to record signals from the motor cortex.
      • Translates signals into commands for onscreen movement, enabling interaction for those with paralysis.
    • Robots and drones
      • Programmable machines for tasks like investigating dangerous materials, bomb disposal, search and rescue, daily chores, cleaning, gardening.
      • Provide therapeutic qualities and social interaction as companions.
    • Wearables
      • Computing devices worn on the body (wrist, arms, face, neck, skin).
      • Contain sensors to transmit signals to smartphones.
      • Include smartwatches, fitness trackers, smart clothing, and implantables.
    • Augmented, mixed, and virtual realities (AR, MR, VR)
      • VR: Computer-generated graphical simulations for the illusion of participation in synthetic environments.
      • MR: Combines real-world views with virtual views where virtual objects are mapped onto physical environments.
      • AR: Virtual representations superimposed on physical devices and objects.
    • Haptic interface
      • Provides tactile feedback using vibration and forces to the user.
      • Embeds actuators in clothes or devices like smartphones or smartwatches.
    • Voice-guided interface (VUI)
      • Enables user interaction with systems through voice commands.
      • Includes devices like Siri, Google Assistant, and Alexa.
      • Voice interaction is becoming more prominent as screens shrink.

    Emotional Interaction

    • Uses knowledge of people's emotions to inform UX design.

    • Emotions like happiness, sadness, annoyance, anxiety, etc., can influence behavior and viewer responses.

    • Relevant examples used in emotional design can include:

      • Online shopping experience
      • Showing photos of hungry children

    • Expressive interfaces can create emotional connections.

    • Emotions can be expressed through various interface elements (Emojis, Sounds, Colours, Shapes, Fonts, Virtual Agents, Animated icons, Sonifications, Vibrotactile feedback).

    Persuasive Technologies

    • Designed to get users to behave in a certain way or change habits.
    • Aims to improve well-being, and are used in numerous domains like: health, fitness, personal relationships.
    • Digital pets (e.g., Tamagotchi, Pokemon) are persuasive systems designed to motivate children to be more active.
    • Fitness/weight trackers motivate behavior change by displaying exercise progress, weight loss, and sleep information, providing goal settings and encouraging competition among users via badges and leaderboards.

    Anthropomorphism

    • People naturally attribute human qualities to animals and objects, for example robots and interactive dolls.
    • Giving human-like attributes to technology makes it more enjoyable and fun for humans to interact with.

    Ethical Design

    • Huge data volumes are collected from users and used in various contexts.
    • Crucial concerns in UX design are user privacy, respectfulness, trustworthiness, fairness, honesty, and human rights.
    • UX designers should make clear how collected data will be used ethically.

    Digital Forgetting

    • Technologies are designed to help people remember, but what about when people want to forget?
    • The study is about developing technologies to allow controlled deletion of digital information without requiring active engagement from the user.

    The Future of HCI

    • Computing power increase leads to new devices and interactions.
    • Interactions will become more immersive and personalized.
    • Humans and computers will be closer as new computing technologies emerge, creating new ways to interact both physically and digitally.

    Affective Computing

    • A subfield of computing dedicated to recognizing and expressing emotions.
    • Used to analyze facial expressions, biosensors, voice/speech quality, body movements.
    • Affective computing systems can predict user behavior and offer solutions for various contexts.
    • Example applications include: detecting driver fatigue, enhancing live video streaming experiences, and making emotional connections.
