The increasing prevalence of dementia in the ageing population combined with the lack of treatments and the burden on national health care systems globally make dementia a public health priority. Despite the plethora of important research findings published over the past two decades, the mechanisms underlying dementia are still poorly understood and the progress in pharmacological interventions is...
This paper presents the design and first prototype of the TactoBook system, a novel concept of reading assistive device that aims to make eBooks accessible to the blind. The TactoBook consists of a computer-based software translator that converts fast and automatically any eBook into Braille. The Braille version of the eBook is then encrypted as a file and stored in a USB memory drive which is later...
This paper introduces a novel miniature piezoelectric ultrasonic motor and its characterization for the design and implementation of Braille tactile displays. The motor consists of a shaft, a mobile element or slider, and a piezoelectric ceramic transducer and achieves linear motion based on the principle of inertia displacement. Unlike existing mechanisms, this motor offers a compact, ultra-lightweight,...
In this paper, the Wii remote (Wiimote) controller and a conventional video camera are used to perform real-time position tracking of an aerial vehicle. The combination of the Wiimote's infrared and video camera fields of view creates a virtual cube in which motion can be fully monitored. This controlled space allows a vehicle to navigate with no onboard sensors. The proposed approach is advantageous...
This paper presents the design and preliminary prototype of the TactoBook, a novel reading assistive device for the blind that is able to reproduce electronic books (eBooks) in portable electronic tactile displays. The TactoBook consists of a computer-based system that translates fast and automatically any eBook into Braille. The Braille version of the eBook is then stored in a USB memory drive which...
