HCI Homework 2 — Lecture 5

In 1965, Ivan Sutherland published The Ultimate Display, a short but remarkably influential paper describing how computers might transform human interaction with virtual environments.

At a time when computer graphics and interactive displays were still emerging, Sutherland imagined systems that could respond to human movement, recognize gaze direction, generate physical forces, and present experiences that would otherwise be impossible in the real world.

In November 2010, Microsoft introduced Kinect for the Xbox 360, a motion-sensing device that allowed people to control games using their bodies instead of conventional handheld controllers.

The concept was ambitious: users could become the controller themselves. By combining depth sensing, computer vision, and real-time human pose estimation, Kinect made full-body interaction available to millions of consumers.

1. Introduction Link to heading

This laboratory consisted of two main activities: setting up a personal academic blog using Hugo and exploring reinforcement learning with Unity ML-Agents.

The first activity focused on creating a functional website for documenting HCI coursework. The second involved configuring a Unity reinforcement learning environment, developing a new agent task, training a policy, and evaluating its performance.

Lecture 1: Affordances Link to heading

The login screen of Genshin Impact is a good example of affordance in a digital interface. A large door is placed at the center of the screen, directly in front of the player. A door naturally suggests the action of entering or passing through it. At the same time, the text “Click to Begin” (点击进入 in the Chinese version) explicitly tells the user how to perform this action.
