Ambutech iglasses
Ambutech HiLites Green 4-Sec 50-in Aluminum Folding Cane-Pencil Tip. The iGlasses Ultrasonic Mobility Aid is a head-mounted device which enables more informed, confident, and efficient pedestrian travel. We found large inter-subject differences in sweeping range and frequency, while the sweeping frequency showed low intra-subject variability. The iGlasses Ultrasonic Mobility Aid is a device worn like a normal pair of. From the Ambutech website: AmbuTech and RNIB are proud to announce a new affordable electronic travel aid solution for head and upper body protection. Grasp type varied among subjects, but was maintained throughout the experiments, with thumb and index finger in contact with the cane handle over 90% of the time. The mean cane tilt angle, sweeping angle, and grip rotation deviation were measured. While a few hand held (MiniGuide, Bissitt and Heyes, 1980) and wearable mobility aids (iGlasses, Shoval et al., 1998, Meers and Ward, 2005) have been developed over the past decades, the majority of ETAs were designed to be mounted on a long cane (Kim et al., 2015, Wang and Kuchenbecker, 2012, Gallo et al., 2010, Kim et al., 2009b, Hoyle and. Royal National Institute of Blind People (RNIB) in the UK and AmbuTech of Canada have partnered to create a pair of sunglasses called iGlasses that detect nearby objects and alert travelers through vibration. Using optical tracking, cameras and inertial measurement units, we investigated grasp type, cane orientation and sweeping characteristics of the long cane with the constant contact technique.
Understanding the characteristics of long cane usage is crucial for the development and acceptance of ETAs. They have developed the assistive technology-enabled solutions, like iGlasses, an ultrasonic mobility aid which detects hurdle on the way and communicates. While a number of Electronic Travel Aids (ETAs) have been developed over the past decades, the conventional long cane remains the most widely utilized navigation tool for people with visual impairments.
