项目摘要
This project will achieve a computerized system that supplies digital content, both lexical and graphical,
suitable for children, students and working adults of the Visually Impaired (VId) community, to increase their
autonomy and potentiate their Quality of Life and societal contribution. While there is notable academic
research, such as a high-density pin display tablet, there is no commercial, broadly functional, full-page
Braille reader. A tablet reader is potentially limiting in comparison with bimanual haptic gloves, limiting any
content complementary to Braille text. In contrast, haptic gloves support both Braille lexical content and
palpable digital images.
The proposed system will encapsulate a full-length Braille reader, not limited to a page at a time but
supplying a limitless stream of characters readable by four fingers in each hand as dictated by the content,
while also supporting haptic actuation of embedded pictorial content. This glove-based approach will unlock,
for an underserved VId clientele, a vast collection of multimedia content currently the exclusive domain of
the seeing population, as Braille lexical content and palpable bas-relief of graphical content.
Phase I will center on a haptic system for Braille display of full-length text, sensed by the fingers of both
hands and based on a redesigned commercial bimanual glove-based haptic system. A software algorithm
will stream and stagger the Braille content to each finger to replicate the bimanual reading process of a VId
reader. The system will also feature a tactile bas-relief version of digital images embedded in the text.
Phase II will develop Haptic VR, demonstrating the utility of overlaying Braille characters on a haptic
curved surface and paving the way for vitally important haptic sensing of labeled 2D/3D graphics by VId
users. A long-term goal is to apply this VR foundation to geolocated Haptic AR, enabling haptic overlay of
Braille labels on everyday surfaces, from appliances to groceries, by suitable integration of haptic rendering
with 3D range-sensing and DNN-based object recognition. Specific Aims – The Phase I Aims are as follows.
Aim 1. High-resolution haptic gloves for Braille streaming- Development of bimanual high-resolution haptic
gloves, featuring dense actuation at eight fingertips, by Haptx. The thumbs will also get haptic feedback.
Aim 2. Haptic rendering of lexical and graphical content
2A. Lexical reader - A software transcription will support spatiotemporal streaming of lexical data that
moves the haptic footprint of Braille characters serially from the first to the eighth finger.
2B. Graphical reader – The conversion of a digital image to a haptic bas-relief will exploit fast DNN-based
image semantic segmentation, where each label will be mapped to an actuator pressure.
2C. Finger-based calibration- Both modalities will be supported by a virtual page defined on a tabletop,
whose coordinates are found by a simple calibration based on three points identified by the index fingers.
该项目将实现一个计算机化系统,提供数字内容,包括词汇和图形,
适合视障人士的儿童、学生及在职人士,以提高他们
提高他们的生活质量和社会贡献。虽然有著名的学术
研究,如高密度针显示平板电脑,没有商业,广泛的功能,全页
盲文阅读器。与双手触觉手套相比,平板阅读器可能是限制性的,限制了任何
补充盲文文本的内容。相比之下,触觉手套支持盲文词汇内容,
明显的数字图像
拟议中的系统将封装一个全长盲文阅读器,不限于一次阅读一页,
提供由内容指定的每只手的四个手指可读的无限字符流,
同时还支持嵌入的图像内容的触觉致动。这种基于手套的方法将解锁,
对于服务不足的Vid客户来说,大量的多媒体内容目前是
能看到的人群,如盲文词汇内容和可触知的浅浮雕图形内容。
第一阶段将集中在触觉系统的盲文显示全长文本,感觉到的手指,
手和基于重新设计的商业双手手套为基础的触觉系统。软件算法
我将把盲文内容流和交错地传送到每个手指,以复制Vid的双手阅读过程
读者该系统还将在文本中嵌入数字图像的触觉浅浮雕版本。
第二阶段将开发Haptic VR,展示在触觉上叠加盲文字符的实用性。
弯曲的表面和铺平道路的至关重要的触觉传感标记的2D/3D图形的Vid
用户.一个长期目标是将这个VR基础应用于地理定位的触觉AR,使触觉覆盖
通过适当集成触觉呈现,在日常表面(从电器到杂货)上使用盲文标签
具有3D范围传感和基于DNN的物体识别。具体目标-第一阶段的目标如下。
目标1。盲文流用高分辨率触觉手套.双手高分辨率触觉手套的开发
手套,具有密集的驱动在八个指尖,由Haptx。拇指也会得到触觉反馈。
目标2.词汇和图形内容的触觉渲染
2A.词汇阅读器-一个软件转录将支持词汇数据的时空流,
从第一个手指到第八个手指连续移动盲文字符的触觉足迹。
2B.图形阅读器-数字图像到触觉浅浮雕的转换将利用基于DNN的快速
图像语义分割,其中每个标签将被映射到致动器压力。
2C.基于手指的校准-两种模式都将由桌面上定义的虚拟页面支持,
其坐标通过基于由食指识别的三个点的简单校准来找到。
