Study summary

This study aims to investigate how visual impairment affects neurophysiological and biomechanical responses during real-world navigation and daily activities, with a focus on the rehabilitative feasibility and impact of assistive technologies. These technologies include applications and wearable devices designed to support various aspects of daily living for individuals with visual impairment. The VIS4ION platform (Visually Impaired Smart Service System for Spatial Intelligence \& On-board Navigation), a wearable system providing tactile and auditory feedback, is one component of this broader study. VIS4ION is designed to enhance environmental awareness and reduce cognitive load during mobility tasks for the visually impaired.

Read the detailed description

Participants with low vision and matched controls will complete walking, navigation, information gathering, and object identification / reaching tasks in both controlled laboratory and real-world environments. Throughout these tasks, physiological measures (e.g., electrodermal activity, heart rate, brain activity, eye movements), biomechanical data (e.g., gait, posture, limb movements), and cognitive metrics will be collected. VIS4ION will be specifically evaluated for its potential to improve the low vision users' scene understanding, navigation efficiency, increase physical activity (e.g., step count, moderate-equivalent minutes), and contribute to improved outcomes in terms of health, awareness, cognitive load, and safety.

Study tasks include obstacle negotiation, dual-task walking, and object identification / reaching under varying conditions (indoor vs. outdoor; with vs. without VIS4ION). A subset of participants will use VIS4ION over extended periods to assess its impact on activities in daily life in real-world settings.

  • Significant depression (score > 11 on the Geriatric Depression scale)
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Study arms

  • Experimental
    Technical Evaluation Group

    Participants, both sighted-blindfolded and people with blindness or low vision, will complete simple navigation, object-identification, and object-reaching tasks, both with and without VIS4ION's services.

    Device: VIS4ION Platform

  • Experimental
    Extended Use Trial: Group A

    Participants with blindness or low vision will complete navigation and object-identification tasks with the device during months 1-6, then without the device during months 6-12.

    Device: VIS4ION Platform

  • Experimental
    Extended Use Trial: Group B

    Participants with blindness or low vision will complete navigation and object-identification tasks without the device during months 1-6, then with the device during months 6-12.

    Device: VIS4ION Platform

Interventions

  • DeviceVIS4ION Platform

    The VIS4ION platform, a non-invasive wearable and smartphone-based system providing auditory (bone-conduction headphones) and haptic (wristband/belt) feedback to enhance mobility and daily living for people with blindness or low vision.

What researchers measure

Primary outcomes

  1. Localization Accuracy Percentage

    Phase I only. Successful location accuracy defined as percentage of attempts with localization accuracy within 1 meter.

    Time frame: Baseline

  2. Orientation Precision Percentage

Secondary outcomes

  1. System Usability Scale (SUS) Score

    Phase II only. 10-item assessment evaluating usability of a system. Each item is rated on a Likert scale from 1-5. The raw score is the sum of responses and is transformed to a standardized score from 0-100; higher scores indicate greater satisfaction.

    Time frame: End of Intervention Period (Month 6 for Group A; Month 12 for Group B)

  2. Change in WHO Quality of Life Brief Instrument (WHO-QoL-BREF) Score

    Phase II only. WHO-QoL-BREF is a 26-item questionnaire assessing quality of life. Each item is rated on a 5-point Likert scale to determine a raw item score. The mean score for each six domains of the questionnaire is calculated, resulting in a mean score per domain that is between 4 and 20. This mean domain score is then multiplied by 4 in order to transform the domain score into a scaled score ranging from 16-80, with a higher score indicating a higher QOL.

    Time frame: Baseline, End of Intervention Period (Month 6 for Group A; Month 12 for Group B)

  3. Change in National Eye Institute Visual Function Questionnaire (VFQ-25) Score

    Phase II only. The VFQ-25 is a 25-item assessment of visual function. Each item is rated on a scale from 0-4; the total score is the sum of responses and ranges from 0-100; higher scores indicate greater vision function and vision quality of life.

    Time frame: Baseline, End of Intervention Period (Month 6 for Group A; Month 12 for Group B)

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Mar 2026; primary completion for Dec 2028, 33 months later.

Of 84 non-industry interventional studies with no phase under Vision Disorders, half reached primary completion within 31 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 51. This study's planned 33 months is close to that.

Counting every sponsor, half of 94 studies reached it within 24 months; a quarter within 6 and three quarters within 51.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 2, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
