Key Findings

01The HM and HH control methods resulted in higher levels of body ownership and were more favored by users.
02The FM control method yielded the lowest body ownership effect and was least favored.
03Both HM and HH control methods were perceived to have high accuracy.

Application

Design takeaway

How to apply

When developing remote control systems, consider incorporating hand-held tracking in conjunction with head-mounted displays to improve user embodiment and perceived presence.

Project actions

01When designing a remote-controlled device, think about how the user will interact with it. Is it natural? Does it feel like they are controlling it directly?
02Consider using multiple input methods that mimic real-world actions to enhance the user's sense of presence.

Method & Evidence

AimTo investigate the impact of different control interfaces (head-mounted display only, head-mounted display with hand-held tracker, head-mounted display with foot-mounted tracker) on user experience, including body ownership, mental and physical load, and motion sickness, when controlling a wearable telexistence robot.

MethodUser study

ProcedureParticipants controlled a snake-shaped wearable telexistence robot using three different interface configurations: HM (head-mounted display only), HH (head-mounted display and hand-held tracker), and FM (head-mounted display and foot-mounted tracker). User experience was assessed using measures of body ownership (Alpha IVBO), workload (NASA-TLX), motion sickness (VRSQ), and a user impression questionnaire.

ContextWearable robotics, remote collaboration, virtual and augmented reality interfaces

Variables

IVControl interface configuration (HM, HH, FM)

DVBody ownership, mental and physical load, motion sickness, user impressions

CVType of wearable robot, task performed, environment

Strengths & Limitations

Strengths

+Investigated multiple aspects of user experience (presence, workload, sickness).
+Compared distinct control interface strategies.

Limitations

The study was conducted in a controlled lab environment, and real-world conditions might introduce different challenges.

Reliability & validity

The use of established scales like NASA-TLX and VRSQ contributes to the validity of the workload and motion sickness measures. Reliability would depend on the consistency of participant responses and the precision of the tracking systems.

Think critically

To what extent can the findings regarding body ownership and preference for control interfaces be generalized to applications beyond telexistence robots, such as virtual reality gaming or remote surgery?

Design Principles

"Intuitive control interfaces that align with natural human motor skills enhance user presence and effectiveness in remote interaction systems."

This research highlights the critical role of intuitive and integrated control interfaces in creating effective remote presence experiences. For designers, it underscores the need to consider the full range of human sensory and motor capabilities when developing systems that aim to bridge physical distance.

What This Means for Your Design

Using a VR headset and a handheld controller to move a remote robot makes you feel more like you are actually there, compared to just using the headset or a foot controller.

Paragraph starter

The investigation into the Piton telexistence robot by Iskandar et al. (2022) demonstrates that control interfaces significantly impact user presence and preference. Specifically, combining a head-mounted display with hand-held tracking yielded higher body ownership and user favorability compared to other configurations, suggesting that intuitive, multi-modal control is crucial for effective remote interaction.
