Short answer

Prioritize display modalities that minimize cognitive load and leverage user familiarity when designing mixed reality applications, especially those requiring divided attention.

Field: Human Factors
Source: Academic Publication (2016)
Method: Experimental study
Evidence: Moderate effect

When designing mixed reality games that require users to divide their attention between the physical and digital worlds, head-mounted displays may lead to performance degradation compared to handheld or wrist-worn devices. This human factors research insight is drawn from a 2016 study published in Academic Publication. Using Experimental study, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Prioritize display modalities that minimize cognitive load and leverage user familiarity when designing mixed reality applications, especially those requiring divided attention.

Head-mounted displays can hinder mixed reality game performance due to attentional demands.

Key Findings

01Participants using the head-mounted display showed poorer performance on one of the game courses.
02Participants generally preferred handheld and wrist-worn displays.
03Familiarity with display types likely influenced user preference.

Application

Design takeaway

Prioritize display modalities that minimize cognitive load and leverage user familiarity when designing mixed reality applications, especially those requiring divided attention.

How to apply

When prototyping mixed reality interfaces for tasks involving navigation or interaction with both digital and physical elements, test different display placements (e.g., head-mounted vs. handheld) to identify which best supports user performance and comfort.

Project actions

01When choosing a display for a project, think about what the user will be doing and how much they need to focus on different things.
02Consider if the user is likely to be familiar with the display type you choose.

Method & Evidence

AimTo evaluate the impact of different wearable display modalities (head-mounted, handheld, wrist-worn) on user performance and preference within a mixed reality game context that demands divided attention.

MethodExperimental study

ProcedureParticipants played a mixed reality game, PhotoNav, which involved navigating using geotagged photographs. The game was played using three different display modalities: head-mounted, handheld, and wrist-worn. Performance metrics (e.g., completion time, accuracy) and user preferences were recorded.

ContextMixed reality gaming, wearable computing interfaces

Variables

IVDisplay modality (head-mounted, handheld, wrist-worn)

DVGame performance (e.g., completion time, accuracy), user preference

CVGame content, navigation task, environmental conditions

Strengths & Limitations

Strengths

+Direct comparison of multiple display modalities.
+Focus on a specific type of demanding user interaction (divided attention).

Limitations

The specific game used might not represent all mixed reality scenarios. The participants' prior experience with different display types could influence their preferences.

Reliability & validity

The study's validity is supported by directly comparing modalities within a controlled game environment. Reliability would depend on consistent task execution and scoring across participants and conditions.

Think critically

How might the design of the mixed reality content itself, rather than just the display modality, influence the observed performance differences?

Design Principles

"Display modality choice should be informed by the task's attentional demands and the target user's experience."

This finding is crucial for designers developing immersive or augmented reality experiences, particularly in gaming or training applications. It suggests that the physical form factor and placement of a display can significantly impact a user's ability to effectively process information and interact with their environment.

What This Means for Your Design

Wearing a screen on your head can make it harder to play some games that need you to look around and pay attention to different things at once, compared to using a phone or watch.

Paragraph starter

The selection of display modality is a critical human factors consideration in mixed reality design. Research indicates that head-mounted displays can negatively impact user performance in tasks requiring divided attention, potentially due to increased cognitive load and reduced situational awareness compared to more familiar handheld or wrist-worn devices (Sharma et al., 2016). Therefore, for interactive mixed reality applications, designers should carefully evaluate the attentional demands of the task and consider display types that minimize user burden and leverage existing user familiarity.
