A protocol to create gene modified human pseudoislets from dispersed human islet cells that are transduced by lentivirus carrying short hairpin RNA (shRNA) is presented. This protocol utilizes readily available enzyme and culture vessels, can be performed easily, and produces genetically modified human pseudoislets suitable for functional and morphological...

Human participants can sort 24-step hue circles accurately. However, sorting 60-step hue circles leads to ordering reversals, impacting color interface design.

Area of Science:

  • Visual Perception
  • Human-Computer Interaction
  • Color Science

Background:

  • Accurate color representation is crucial for digital interfaces.
  • Understanding human perception of hue is essential for effective color selection tools.

Purpose of the Study:

  • To investigate human ability to sort hues at varying resolutions.
  • To identify limitations in hue discrimination with increased color steps.
  • To inform the design of user interfaces for color selection.

Main Methods:

  • Participants sorted hue chips presented in circular arrays.
  • Hue circles varied in resolution from 6 to 60 steps.
  • Performance was evaluated based on ordering accuracy and reversals.

Main Results:

  • Participants accurately sorted 24-step hue circles.
  • Significant ordering reversals occurred when sorting 60-step hue circles.
  • The pattern of reversals varied depending on the specific hue region.

Conclusions:

  • Human hue discrimination has limits, especially at higher resolutions.
  • Current digital color palettes may present challenges for precise user sorting.
  • Findings suggest optimizing color picker interfaces to account for perceptual limitations.
