“…This development was carried out to help children with visual impairments detect braille and respond to text by connecting it to an android, even this automatic braille point detector is able to read braille text in image form (Sulviyani et al, 2017), supported by a braille mouse which is the central connection for social media for use on smartphones or tablets which can greatly influence the development of social interaction, and the use of the latest technology that is connected to social media platforms in the form of chat quickly and can be used anywhere because it was developed without cable (Holanda et al, 2018).…”

The innovation of braille makes learning for children with visual impairments easier. The breakthrough braille innovation developed is able to encourage the creation of creative, active, and practical learning for children with visual impairments. This study aims to collect and analyze articles related to innovation technology of braille for teaching and learning process to visual impairment. The design of study used literature review that use data collection methods with search related topics, data analysis and also writing research results. The results of this study that braille innovations technology for reading, writing and conceptualizing of reading are useful in the learning process of children with visual impairments.

“…One of the most significant function of this system is that, the program uses TTS function to output ai as speech, which provides a more comfortable way for the blind to use the dictionary. In addition, several works in the past focused on OCR in android applications [35,36], real-time OCR [37], character readability on smart phones [38], character recognition models suitable for handheld devices [39], and App to recognize food items in Chinese menu [40]. Considering several related work, it is evident that, none of the previous research focused on developing a method to visually understand the text only by scanning.…”

Majority of Chinese characters are pictographic characters with strong associative ability and when a character appears for Chinese readers, they usually associate with the objects, or actions related to the character immediately. Having this background, we propose a system to visualize the simplified Chinese characters, so that developing any skills of either reading or writing Chinese characters is not necessary. Considering the extensive use and application of mobile devices, automatic identification of Chinese characters and display of associative images are made possible in smart devices to facilitate quick overview of a Chinese text. This work is of practical significance considering the research and development of real-time Chinese text recognition, display of associative images and for such users who would like to visualize the text with only images. The proposed Chinese character recognition system and visualization tool is named as MyOcrTool and developed for Android platform. The application recognizes the Chinese characters through OCR engine, and uses the internal voice playback interface to realize the audio functions and display the visual images of Chinese characters in real-time.

“…In this study, to classify research documents, first, OCR will be used. Optical Character Recognition (OCR) acquires an image through the use of a device, usually a camera or scanner, and then converts it to digital text [5][6] [7]. Then, supervised term weighting schemes are applied to assign a weight for each term in every document, enhancing text classification performance [8].…”

Natural Language Processing, specifically text classification or text categorization, has become a trend in computer science. Commonly, text classification is used to categorize large amounts of data to allocate less time to retrieve information. Students, as well as research advisers and panelists, take extra effort and time in classifying research documents. To solve this problem, the researchers used state-of-the-art supervised term weighting schemes, namely: TF-MONO and SQRTF-MONO and its application to machine learning algorithms: K-Nearest Neighbor, Linear Support Vector, Naive Bayes Classifiers, creating a total of six classifier models to ascertain which of them performs optimally in classifying research documents while utilizing Optical Character Recognition for text extraction. The results showed that among all classification models trained, SQRTF-MONO and Linear SVC outperformed all other models with an F1 score of 0.94 both in the abstract and the background of the study datasets. In conclusion, the developed classification model and application prototype can be a tool to help researchers, advisers, and panelists to lessen the time spent in classifying research documents.
