In collaborative tabletop environments using multiple devices, selecting targets by being close to them (proximity pointing) is more efficient and accurate than directly placing a cursor on the target (direct pointing). This human factors research insight is drawn from a 2022 study published in Multimedia Tools and Applications. Using Empirical study with 62 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing collaborative interfaces for shared tabletops, implement proximity-based selection as the default, rather than direct cursor placement, to improve user efficiency and accuracy.
Proximity pointing outperforms direct pointing in cross-device collaborative tabletop interactions.

Key Findings
- 01Proximity pointing resulted in significantly shorter completion times compared to direct pointing.
- 02Proximity pointing demonstrated higher operation correctness (fewer errors) than direct pointing.
- 03Users accustomed to single-device interactions showed a learning curve when adapting to cross-device interactions.
Application
Design takeaway
When designing collaborative interfaces for shared tabletops, implement proximity-based selection as the default, rather than direct cursor placement, to improve user efficiency and accuracy.
How to apply
When developing interfaces for interactive whiteboards or shared digital tables used by multiple people with their own devices, design the cursor selection to activate when the cursor is within a certain radius of the target, rather than requiring exact placement.
Project actions
- 01When designing a collaborative interface, test both direct and proximity pointing methods.
- 02Consider how users will learn and adapt to your cross-device interaction system.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Empirical data collected from a substantial number of participants.
- +Direct comparison of two fundamental pointing techniques in a relevant context.
Limitations
The study's findings might be specific to the resolution and size of the display used, or the types of targets being selected. The complexity of the collaborative task itself could also influence the results.
Reliability & validity
The study's validity is supported by the empirical comparison of performance metrics. Reliability would be enhanced by ensuring consistent task presentation and precise measurement of time and errors across all participants.
Think critically
How might the optimal pointing technique change depending on the complexity of the target object, the density of targets on the screen, or the specific nature of the collaborative task?
Design Principles
"In multi-device collaborative environments, proximity-based selection can enhance task performance over direct selection."
This finding challenges conventional interaction paradigms that favor direct manipulation. Designers of collaborative systems, particularly those involving shared displays and individual mobile devices, must reconsider default interaction models to optimize user performance and reduce errors.
What This Means for Your Design
When people work together on a big screen using their phones, it's better to let them click things by getting close to them with the cursor, not by putting the cursor exactly on the thing. This makes it faster and easier.

Paragraph starter
In collaborative design projects involving shared displays and individual devices, user performance can be significantly impacted by the chosen pointing technique. Research indicates that proximity pointing, where a cursor selection is registered when it is near a target, is more efficient and accurate than direct pointing, where the cursor must be precisely on the target. This is particularly relevant for cross-device interactions where users may be adapting from single-device paradigms, suggesting that proximity-based selection can mitigate potential usability issues and improve overall task completion.
