“…The experiment was conducted in an indoor space measuring 5.7 × 3.6 m. At the heart of the experimental equipment is the BWT61CL model Inertial Measurement Unit (IMU), a common positioning mechanism responsible for monitoring the directional changes of participants before and after receiving directional feedback [ 54 ]. Despite the presence of cumulative errors, its accuracy in estimating the position and body orientation of participants can be enhanced by refining directional errors [ 6 ], ensuring a measurement precision within 0.5° on the Z-axis.…”

Most navigation aids for visually impaired individuals require users to pay close attention and actively understand the instructions or feedback of guidance, which impose considerable cognitive loads in long-term usage. To tackle the issue, this study proposes a cognitive burden-free electronic travel aid for individuals with visual impairments. Utilizing human instinctive compliance in response to external force, we introduce the “Aerial Guide Dog”, a helium balloon aerostat drone designed for indoor guidance, which leverages gentle tugs in real time for directional guidance, ensuring a seamless and intuitive guiding experience. The introduced Aerial Guide Dog has been evaluated in terms of directional guidance and path following in the pilot study, focusing on assessing its accuracy in orientation and the overall performance in navigation. Preliminary results show that the Aerial Guide Dog, utilizing Ultra-Wideband (UWB) spatial positioning and Measurement Unit (IMU) angle sensors, consistently maintained minimal deviation from the targeting direction and designated path, while imposing negligible cognitive burdens on users while completing the guidance tasks.
