To discover how visually impaired volunteers would prefer to receive these vibrations, the team developed two different presentation methods. In the first, the user touches the screen on the left-hand side to read whether or not there is a bump in that position of the matrix, then moves their finger horizontally across the screen to read the …

V-Braille is a novel way to haptically represent Braille characters on a standard mobile phone using the touch-screen and vibration. V-Braille may be suitable for deaf-blind people who rely primarily on their tactile sense. A preliminary study with deaf-blind Braille users found that, with minimal training, V-Braille can be used to read ...

For example, previous studies showed that vibration feedback can facilitate visually impaired and blind users to access visual information on touchscreen in the static condition (Lahib et al., 2018; Tekli et al., 2018). However, in vibration environments, both human body and touchscreen devices vibrate.

Reaction wheel assembly (RWA) is an attitude control actuator for spacecraft. Its induced micro vibration will have a harsh effect on the performance of sensitive payloads. In this paper, a compact four-legged vibration isolation system for RWA is designed and investigated. Piezoelectric stack actuators (PSA) are chosen and dynamic equations are …

The aim of the experiment was to establish whether the use of different and complex vibrations had a better success ratio in terms of the users' ability to memorize the locations of haptic icons on the smartphone screen. Additionally, the experiment sought to conclude if the improvement applied to visually impaired people.
