INFLUENCE OF LIGHT LEVELS ON VISIBILITY FOR SAFETY AT AUTOMATED TELLER MACHINE FACILITIES

摘要

People need light to safely use an automated teller machine (ATM) at night. Standards and recommendations for the amount of lighting, as well as the locations to be lighted, at ATMs differ across organizations and jurisdictions. The objectives of the present study were to identify relevant visual tasks that the customer needs to perform for efficient and safe use of the ATM, and to investigate how different light levels impact performance of those tasks. The results indicate that minimum illuminances of 10 lx at and around the ATM are sufficient to achieve adequate visual performance for safety-related visual tasks such as those evaluated in the present study. The present findings suggest that a minimum illuminance of 10 lx can be sufficient for many visual tasks required for safe ATM use. Visibility analyses using the relative visual performance model can be useful in evaluating lighting in the ATM environment.
