Public expectations for zoom control labels on remote lenses were investigated. No stereotype was found for standard buttons or rocker switches, but a novel design based on user suggestions showed a significant stereotype for zoom direction control.

Area of Science:

  • Human-Computer Interaction
  • Usability Engineering
  • Control Systems Design

Background:

  • Understanding user expectations is crucial for intuitive interface design.
  • Previous research has explored population stereotypes for various controls, but zoom lens controls lack established conventions.
  • The relationship between physical controls and perceived function significantly impacts user experience.

Purpose of the Study:

  • To investigate public expectations for the labeling of zoom controls (pushbuttons and rocker switches) on remote-controlled lenses.
  • To determine if a population stereotype exists for zoom direction control.
  • To evaluate a novel button arrangement designed to align with user-suggested labels.

Main Methods:

  • Two experiments were conducted involving members of the public.

  • Experiment 1 assessed expectations for standard pushbutton and rocker switch arrangements for zoom control.
  • Experiment 2 tested a novel concentric button design informed by Experiment 1 findings.

    • Main Results:

    • No population stereotype was found for either the pushbutton or rocker switch arrangements.
    • Participants frequently suggested 'Zoom In/Zoom Out' or 'Close-up/Distant' as labels.
    • The novel concentric button arrangement demonstrated a significant stereotype aligned with these user-suggested labels.

    Conclusions:

    • Standard pushbutton and rocker switch designs lack an intuitive mapping for zoom control direction.
    • User-generated labels provide valuable insights for designing more intuitive zoom controls.
    • A concentric button design can effectively embody user expectations for zoom direction, improving usability.
