Short answer

For public interactive displays, use immediate mirroring of the user's form as the primary way to signal interactivity, as this significantly increases engagement compared to text-based calls-to-action.

Public displays that immediately mirror user silhouettes or images are significantly more effective at attracting interaction than traditional call-to-action sequences. This user-centred design research insight is drawn from a 2012 study published in Academic Publication. Using Mixed-methods (lab study and field study) with 502 interaction sessions (field study), researchers explored how this design variable affects real-world outcomes. The key design takeaway: For public interactive displays, use immediate mirroring of the user's form as the primary way to signal interactivity, as this significantly increases engagement compared to text-based calls-to-action.

Key Findings

  • 01Mirrored user silhouettes and images are more effective than avatar-like representations in communicating interactivity.
  • 02It takes approximately 1.2 seconds for passers-by to notice interactivity.
  • 03Immediate mirroring of user images/silhouettes increased interaction by 90% and 47% respectively, compared to traditional attract sequences.
  • 04Users often notice interactivity late and may need to walk back to engage (landing effect).
  • 05Existing users can draw in new users, creating multiple rows of interaction (honeypot effect).

Application

Design takeaway

For public interactive displays, use immediate mirroring of the user's form as the primary way to signal interactivity, as this significantly increases engagement compared to text-based calls-to-action.

How to apply

When designing interactive installations for public spaces, such as digital signage or interactive window displays, ensure the system immediately reflects the user's presence through mirroring before any other content is shown.

Project actions

  • 01When prototyping interactive displays, test different visual feedback methods to see what grabs attention fastest.
  • 02Consider the user's journey and how they might approach the display from different angles and distances.

Method & Evidence

AimHow can the visual feedback of public displays be designed to effectively communicate interactivity to passers-by and encourage engagement?
MethodMixed-methods (Lab study and Field study)
ProcedureA lab study was conducted to compare different visual feedback methods (mirrored silhouettes/images vs. avatar-like representations). A field study then deployed three interactive displays in shop windows for three weeks, collecting data on 502 interaction sessions to observe real-world engagement patterns.

Strengths & Limitations

Strengths

  • +Combines controlled lab conditions with real-world field study observations.
  • +Provides quantitative data on interaction increases.
  • +Identifies specific user behaviours ('landing effect', 'honeypot effect').

Limitations

The effectiveness might vary depending on the specific context (e.g., time of day, type of location) and the design of the mirrored representation.

Reliability & validity

The field study's large sample size and real-world context enhance ecological validity, while the lab study provides controlled conditions for comparing specific feedback types. Reliability is supported by consistent observations of user behaviour across multiple instances.

Think critically

How might the 'honeypot effect' be leveraged or mitigated depending on the desired outcome for the interactive display?

Design Principles

"Immediate visual mirroring of user presence is a powerful and intuitive cue for communicating interactivity in public spaces."

Understanding how users perceive and engage with interactive public displays is crucial for designing effective installations. This insight provides a quantifiable method to increase user engagement by leveraging intuitive visual feedback, directly impacting the success of public-facing interactive design projects.

What This Means for Your Design

If you want people to interact with a public screen, show them their own reflection right away. It works much better than just telling them to interact.

Paragraph starter

The design of interactive public displays significantly impacts user engagement. Research indicates that immediate visual mirroring of user silhouettes or images is a highly effective method for communicating interactivity, leading to substantial increases in user interaction compared to traditional attract sequences. This suggests that intuitive, real-time visual feedback is paramount for drawing users into interactive experiences in public spaces.
