[HCI] L1-3. Exploring HCI

1. Technology

Virtual Reality

• tourist
• commerce
• art
• education
• medical
  • VR Therapy and Counseling Center, Grand Rapids, Michigan
    • treat phobia

Augmented Reality

UbiComp and Wearble

• Ubiquitous Computing : computing power anytime, anywhere ~= IoT (Internet of Thing)

Robotics

• Human Robot Interaction : new field!

Mobile

• Mobile : portable computing devices built to be used easily on the go

2. Idea

Context-Sensitive Computing

• Equipping user interfaces with historical, geographical, or other forms of contextual knowledge.

• context는 인간 사이의 상호작용에서 가장 중요한 부분
  • Q. 몇시에요? / A. 이제 점심먹으러 가도 돼요
• ex) 차안에서 google map 자동으로 켜주기 / 소파에서 쉴 때 노래를 틀어주기

Gesture-Based Interaction

• Interacting with interfaces using hand or body gestures
• ex) invisible keyboard - recoginze movement of the muscle in wrist

Pen- and Touch-Base Interaction

Information Visualization

• Representing abstract data visually to help humans understand it

• ex)

  • emperature of the World since 1850, also in animated form
  • Visualization of the distribution of PIN usage for debit cards
  • The Age Distribution of the United States from 1933 to 2100 (Projected)

CSCW (Computer-Supported Cooperative Work)

• using computers to support people working together

Social Computing

• re-creating social norms within computational systems

3. Domain

Special Needs

• ex) Bruce Walker, Sonification Lab in Georgia Tech
  • How to communicate data to a blind person?
    • Data visualization -> “communicating data using sound”

Education

• education is area where you might not want to make things as easy as possible
  • You might use HCI to introduce some desirable difficulties, some learning experiences for students
• cognitive load students experienced during a learning task is based on the material itself not based on trying to figure out our interfaces.
  • In WORST case, HCI for education is raise the students’s cognitive load because they’re too busy thinking about interfaces instead of the subject matter itself

-> 중요한 시사점을 주는 대목…!

lots of novel efforts in designing technology for education have failed due to poor HCI

Healthcare

Security

• For security to be useful it has to be usable
  • If it isn’t usable people just won’t use it
• HCI can increase the usability of security
  • CAPTCHAs
  • password selection like a game
    • ranked against others for how difficult your password would be to guess
    • incentivise password selections…!

Games

• there’s a tight connection between the task and the interface
  • 즉, task 수행의 불편함을 통해 interface 문제를 빠르게 파악할 수 있다!

Conclusion

• 위의 내용을 명심하고 내가 관심있는 Domain과 HCI를 연관시켜 나가며 공부할 것!
