Image to Haptic Data Conversion: A First Step to Improving Blind People’s Accessibility to Printed Graphs
نویسندگان
چکیده
This paper introduces a system which converts scanned line graphs into a data format which is interpretable by a haptic device. A virtual line graph can then be rendered and explored through touch by using the haptic device. This system provides an alternative method for blind or visually impaired people to access printed graphs. This method has a simpler production process than the conventional raised paper. Moreover, exploring graphs through a haptic device can provide assistance and guidance to less confident users. At the current stage, simple line graphs can be converted and rendered on two haptic devices: SensAble PHANToM and Logitech WingMan force feedback mouse. Evaluation of the system is being carried out and further improvements have been

Assistive Multimodal Interfaces for Improving Web Accessibility
Multimodal interfaces have been used in helping blind and partially sighted people to access visualization tools such as graphs and numerical tables. However, few studies have been undertaken to improve Web access and navigation using a multimodal approach. This paper describes a novel approach that addresses this Web accessibility issue by using an assistive tool which consists of a multimodal...
متن کاملSteganography Scheme Based on Reed-Muller Code with Improving Payload and Ability to Retrieval of Destroyed Data for Digital Images
In this paper, a new steganography scheme with high embedding payload and good visual quality is presented. Before embedding process, secret information is encoded as block using Reed-Muller error correction code. After data encoding and embedding into the low-order bits of host image, modulus function is used to increase visual quality of stego image. Since the proposed method is able to embed...
متن کاملTechniques for Improving Accessibility of Mobile Applications for Blind and Visually Impaired Users
This paper provides a synopsis of several methodologies for improving the accessibility of mobile devices and applications for persons who are blind or visually impaired. Areas of focus include an analysis of different input methods, including tactile key presses and gesture-based touch screen input. Also, the paper looks closely into the non-visual device responses in terms of verbal and non-v...
متن کاملPSO-Optimized Blind Image Deconvolution for Improved Detectability in Poor Visual Conditions
Abstract: Image restoration is a critical step in many vision applications. Due to the poor quality of Passive Millimeter Wave (PMMW) images, especially in marine and underwater environment, developing strong algorithms for the restoration of these images is of primary importance. In addition, little information about image degradation process, which is referred to as Point Spread Function (PSF...
متن کاملHaptic Representation of Scientific Data for Visually Impaired or Blind Persons
Interpretation and understanding of complex scientific data is enhanced by graphic representation. For those people with visual impairments, this method is inadequate. An alternative, or additional, method is to represent the data using other modalities, namely touch and hearing. Haptic display of such graphical data adds kinesthetic feedback that provides the sense of touch. Audio feedback add...
