A new compatible chord code for Chinese character input (ECC) improves computer input speed. Graphic compatibility between elements and key combinations on a chord keyboard was key, outperforming random mapping without explicit visual cues.

Area of Science:

  • Human-Computer Interaction
  • Computer Science
  • Linguistics

Background:

  • Efficient input methods for complex character sets like Chinese are crucial for computer usability.
  • Existing methods often involve trade-offs between speed, learning curve, and cognitive load.
  • Chord keyboards offer potential for high-density input but require effective encoding strategies.

Purpose of the Study:

  • To propose and evaluate a novel compatible chord code for inputting elements of Chinese characters (ECC).
  • To leverage the graphic compatibility between ECC and chord combination of keys (CCK) on a five-key, single-handed chord keyboard.
  • To compare the performance of the compatible chord code against a randomly mapped code.

Main Methods:

  • Development of a compatible chord code based on visual similarities between Chinese character elements and key combinations.

Related Experiment Videos

  • Implementation of a single-handed chord keyboard with five keys.
  • Experimental comparison of learning time and response time between the compatible chord code and a randomly mapped code.
  • Assessment of the impact of explicit graphic compatibility cues on memorization.

    • Main Results:

    • The proposed compatible chord code demonstrated superior performance compared to random mapping.
    • Users exhibited significantly reduced learning time and response time with the compatible chord code.
    • Explicitly indicating the graphic compatibility did not lead to enhanced memorization of the code.

    Conclusions:

    • A compatible chord code capitalizing on graphic similarities offers an efficient method for Chinese character computer input.
    • The design principle of leveraging inherent visual compatibility is effective for chord keyboard encoding.
    • Further research may explore alternative methods for enhancing code memorization beyond explicit visual cues.
