![]() While smartphone devices are essential tools for many people who are blind and visually impaired, these devices pose significant security and privacy risks for them. more Blind people use smartphone devices to perform many daily activities like mobile banking, social media, shopping, health care, etc. It also presents the implementation of Grade 2 and an initial evaluation of the improved SingleTapBraille keyboard with a blind user.īlind people use smartphone devices to perform many daily activities like mobile banking, social. This paper presents our initial keyboard design to enter Grade 1 and our explorative evaluation of SingleTapBraille conducted with braille instructors and visually impaired users. With SingleTapBraille, a user enters characters including text, numbers, and punctuations by tapping anywhere on the screen with one finger or a thumb several times based on braille patterns. In this paper, we describe SingleTapBraille, a novel nonvisual text input approach for touchscreen devices. However, most of the available touchscreen keyboards are still largely inaccessible to blind and visually impaired people because they require the user to find an object location on a touchscreen in order to interact with an application. Visually impaired people tend to use touchscreen devices because these devices support a screen reader function, providing a cheaper, smaller alternative to screen reader machines. more Touchscreen technology has brought about significant improvements for both normal sighted and visually impaired people. Touchscreen technology has brought about significant improvements for both normal sighted and vis. However, in order to increase the efficiency of BrailleTap further development of the underlying algorithm is required. Results indicate that BrailleTap is faster and more accessible to blind users than the traditional touchscreen calculator. This paper presents our pilot study of BrailleTap that was conducted with two blind users. Alternatively, using a swipe gesture, the user will be orally prompted to select the desired arithmetic operations. Using finger tap, the user can input a number in braille and the application will compute the braille code to its corresponding numerical value. BrailleTap is a button-free calculator application for touchscreen devices that utilizes tap gestures to operate. To fill this void, this paper proposes BrailleTap. There is currently no application that simplifies the calculator user-interface for individuals with limited or no vision. To overcome this challenge, prior to use these individuals must invest additional time and energy into memorizing the calculator layout. This poses a challenge for individuals with limited or no vision. more Touchscreen calculators require a user to visually locate a button on the screen. Touchscreen calculators require a user to visually locate a button on the screen. There is also a need to improve the CAPTCHA solution to cover wide range of users by adding corresponding image with each sound to meet deaf users' needs they then need to identify the spelling of the sound maker's word. To increase the security of HearAct, it is necessary to increase the number of sounds in the CAPTCHA. Using gestures to solve the CAPTCHA challenge is the most preferable feature in the HearAct solution. A significant usability differences between the System Usability score for HearAct CAPTCHA method was 88.07 compared to audio CAPTCHA was 52.11%. ![]() The results of the study also show that the success rate of solving the HearAct CAPTCHA is 82.05% and 43.58% for audio CAPTCHA. Thus, participants preferred HearAct over audio-based CAPTCHAs. The results also show that the HearAct CAPTCHA can be answered in a shorter time than the text-based CAPTCHAs because HearAct allows users to solve the CAPTCHA using gestures instead of typing. The preliminary user study results suggest the new form of CAPTCHA has a lot of potential for both blind and visual users. This paper presents our HearAct pilot study conducted with thirteen blind users. If the word has the letter, the user must tap and if not, they swipe. After that, HearAct identifies a word and requires the user to analyze a word and determine whether it has the stated letter or not. The user listens to the sound of something (the "sound-maker"), and he/she must identify what the sound-maker is. To address the issue, this paper proposes a new mechanism for CAPTCHA called HearAct, which is a real-time audio-based CAPTCHA that enables easy access for users with visual impairments. ![]() However, traditional text-based CAPTCHAs are not suitable for sighted users much less users with visual impairments. more CAPTCHAs are widely used by web applications for the purpose of security and privacy.
