SPARK: Supporting Physical Activity Through Reality-Augmented Knowledge in COPD (SPARK)

September 17, 2026 updated by: Groupe Hospitalier du Havre

Acceptability of an Augmented Reality Virtual Coach for Physical Exercise Practice in Patients With Chronic Obstructive Pulmonary Disease: a Multicenter Study

Chronic obstructive pulmonary disease (COPD) is associated with dyspnea, reduced physical activity, muscle deconditioning, and impaired quality of life. Pulmonary rehabilitation is an effective non-pharmacological intervention, but access remains limited and long-term adherence to physical exercise is often difficult to maintain. Augmented reality may provide an innovative approach to support exercise practice by offering real-time visual and auditory guidance while allowing patients to remain anchored in their real environment.

The SPARK study is a multicenter, interventional, non-randomized, proof-of-concept study designed to assess the acceptability of an augmented reality virtual coach for physical exercise in adults with COPD. Participants will attend a single experimental session including baseline questionnaires, presentation of the augmented reality headset, a short immersive exercise session guided by a virtual coach, and post-immersion assessments. Acceptability will be evaluated using the Technology Acceptance Model 3 questionnaire before and after immersion. User experience will also be explored through focus group discussions analyzed according to UXive dimensions.

The study aims to determine whether this technology is acceptable to patients with COPD and to identify factors that may facilitate or limit its future integration into pulmonary rehabilitation pathways.

Intervention / Treatment
Experimental: Augmented Reality Virtual Coach Session

Participants with chronic obstructive pulmonary disease will attend a single experimental session using an augmented reality headset with a virtual coach. After baseline questionnaires and headset presentation, participants will complete an approximately 20-minute guided exercise session including calf raises, sit-to-stand exercises, and stretching. The virtual coach provides standardized instructions and corrective feedback during strengthening exercises. Acceptability will be assessed before and after immersion using the TAM3 questionnaire, followed by a focus group exploring user experience.

Participants will use an augmented reality headset delivering a virtual coach-guided exercise session. The intervention consists of a single approximately 20-minute immersive session performed in a secured environment. The virtual coach provides standardized instructions and corrective feedback during strengthening exercises. The session includes calf raises, sit-to-stand exercises, and stretching. The intervention is designed to assess the acceptability and user experience of an augmented reality-based exercise support tool in adults with chronic obstructive pulmonary disease.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Global Acceptability Score of the Augmented Reality Virtual Coach
Time Frame: Immediately after the augmented reality immersion session, during the single study visit

Acceptability will be assessed using the global score of the adapted Technology Acceptance Model 3 questionnaire completed immediately after the augmented reality immersion session. Items are rated on a 7-point Likert scale, with higher scores indicating greater acceptability. The mean global score will be compared with the theoretical neutral value of 4.
