1 TARIFF PRIVACY-FOCUSED ADAPTIVE BRAILLE INTERFACE FOR VISUALLY IMPAIRED INDIVIDUALS. MOBILE ACCESS SYSTEM TECHNICAL AREA 5 The invention addresses the privacy aspects of existing systems for the use of mobile devices by visually impaired individuals. To eliminate the problems of insufficient and fixed access output, the user's tactile perception The profile evaluates finger touch and pressure data together with environmental privacy conditions. a mobile device that adapts physical relief parameters and access mode in real time It includes the access system. 10 The invention addresses, in particular, the privacy issues faced by visually impaired individuals when accessing mobile devices. The problem includes technical limitations such as fixed access output and a non-personalized user experience. It offers an innovative adaptive mobile access system that aims to overcome existing smart Phones primarily rely on voice commands, screen readers, or fixed 15 for visually impaired users. Solutions such as vibration feedback are being used, and these systems are suitable for crowded environments. This leads to a privacy violation, providing a physical reading experience for users who know Braille. It cannot be offered because each user's touch sensitivity, reading speed, or finger pressure is different. It produces a fixed access output even though it has a dynamic Braille display or embossed display. Surface solutions also mostly produce fixed Braille output; the user's tactile perception 20 It adjusts itself according to its profile, fingerprint data, and environmental privacy conditions. It does not adapt. This invention solves the aforementioned technical problems by integrating it into the mobile device body. tactile surface capable of creating dynamic raised patterns, Braille output module, finger contact and This includes a pressure sensor, user haptic feedback profile memory, and ambient and privacy sensing unit. It solves the problem through a system consisting of adaptive decision algorithms that process the data together. 25 The system uses a finger contact and pressure sensor to detect the user's finger position and the pressure they apply. It detects pressure level and reading speed; the user's tactile perception profile is stored in its memory. Personalized access preferences, ambient sound from the ambient and privacy sensing unit, Simultaneously displays data such as headphone connection and crowd indicator. It evaluates this data. The adaptive decision algorithm analyzes this data together for each user and 30 Braille dot height, relief hardness, and vibration will vary depending on the ambient conditions. It dynamically determines the support and audio / tactile access mode; thus, it does not support fixed Braille. real-time and beyond the reliance on print or voice screen readers. It provides a personalized access experience. The system also includes a navigation bump module. It transmits route and direction information through linear relief and vibration patterns, with only the active finger 35 Energy management unit that creates a bulge in the areas where it is in contact with unnecessary energy. 2 by reducing consumption and learning the user's reading behavior during use, for subsequent use. It includes a user behavior learning module that improves access settings in various uses. PREVIOUS TECHNIQUE Current technologies for visually impaired individuals to access mobile devices are predominantly audio-based. screen readers, stable vibration feedback, and static haptic feedback solutions It is based on the screen that is built into today's smartphone operating systems. Reader software uses synthetic speech synthesis to render visual content on the screen, such as text, menus, and notifications. It conveys this to the user; in addition, it provides notifications or guidance through simple vibration patterns. Information can be provided. Voice feedback systems allow visually impaired users to access information on mobile devices. While it is a widely used solution in access, the use of these systems is problematic for large crowds. in environments, on public transport or in public spaces where privacy is important, Because the sound emitted from the device can be heard by people in the vicinity, the user's privacy is a concern. leading to the unwanted disclosure of information, message content or personal data This opens up and creates a serious privacy issue. Due to privacy concerns, audio 15 In cases where screen reader usage is restricted, visually impaired users can access their devices. Access is significantly restricted or completely blocked. In this context, While users have the option to turn off voice feedback according to their own preference, In this situation, the lack of a haptic feedback alternative makes the user's interaction with the device almost impossible. It makes it impossible. 20 When current tactile access solutions are examined, some have been developed for visually impaired individuals. These devices feature dynamic Braille displays or embossed tactile surfaces. systems with electronically controlled rising pins or similar raised elements It is able to physically create Braille characters through this. However, this dynamic 25 Tactile surfaces display Braille characters at a fixed height, depending on the content of the text being read. It produces a constant stiffness and an unchanging vibration profile; catering to the user's individual tactile perception. according to its characteristics, finger sensitivity, reading speed, or the force of pressure it applies It does not make any adaptations. However, tactile feedback is available among visually impaired users. Detection thresholds, fingertip sensitivity, Braille reading speed, and preferred embossing height 30 There are significant individual differences in this regard; these differences are not limited by fixed parameters. The current dynamic Braille displays are not easily readable by some users, This leads some users to perceive it as insufficient or excessive. Low For a user with tactile sensitivity, fixed and low-height Braille dots are sufficient. While it doesn't provide any perception, the same raised height is uncomfortable for a highly sensitive user. 35 This can be distracting or slow down reading speed. Similarly, user finger contact the failure to detect the pressure force applied during the process or any adaptation of this data 3 not being used in the process, existing systems are completely passive against user behavior. This leads to it remaining stagnant and failing to offer a personalized access experience. Furthermore, Current dynamic Braille displays detect the position of the user's finger on the surface or Because it does not include a system that detects which area it is in contact with, it can touch the entire surface or a large area. Creating a raised area leads to unnecessary energy consumption and a physically complex tactile experience. 5 This causes the environment to be created. Another significant shortcoming of current technologies is their ability to take into account the environmental conditions of the user. and an access mode switching mechanism that takes privacy requirements into account The problem is its absence. The user, concerned about privacy in a crowded environment, chooses not to use the voice screen reader. When you want to turn it off, the existing systems automatically switch to haptic Braille mode. It does not do this; the user has to make this transition manually, which is particularly important. Accessibility for users with underdeveloped Braille reading skills or who cannot switch between modes quickly. This creates a difficulty. Ambient noise level, headphone connection status, location information, or Parameters such as user-defined privacy preferences are currently available. 15 not being taken into consideration in their systems, being context-sensitive, intelligent and This constitutes the most fundamental obstacle to an autonomous access experience. The current haptic feedback loop... Access solutions are also limited in the transmission of navigation and directional information; maps, Spatial data such as route, turn, and obstacle information is provided only through audio announcements or constant vibration. presented with patterns, tactile guidance such as linear relief or raised edges 20 These techniques are either absent or inadequately applied on existing dynamic surfaces. This situation makes it particularly difficult for visually impaired individuals to navigate open spaces or complex indoor environments. This directly affects independent mobility and the current navigation solutions. This results in inadequate tactile access. All these technical limitations... When they come together, privacy and personalization in mobile device use by visually impaired individuals, 25 There are serious shortcomings in terms of energy efficiency and contextual adaptability, currently technologies fail to fully meet user needs, and digital technologies are not available to visually impaired individuals. It is clear that technical barriers to equal access to the world persist. This invention solves all of these technical problems by integrating 30 components into the mobile device body. Dynamic texture-generating tactile surface, Braille output module, finger contact and pressure. the sensor, user haptic feedback profile memory, and ambient and privacy sensing units solving it through an adaptive decision algorithm that processes incoming data in real time The invention aims to reduce the pressure force applied by the user during finger contact. Sensor data that detects contact duration and reading speed, along with the user's haptic perception profile. 35 By considering your registered preferences and the privacy conditions in the environment together; Braille dots height, embossing stiffness, vibration support, and audible or haptic feedback mode can be dynamically adjusted. 4 by defining it as such, going beyond existing fixed and context-free access systems, It aims to provide a real-time and fully personalized access experience. Furthermore, the invention creates an energy bulge only in the active area where there is finger contact. The management unit optimizes energy consumption, and the navigation relief module provides spatial guidance. It transmits information using linear relief and vibration patterns, learning user behavior module 5 By analyzing the user's reading habits over time, it continuously adjusts access settings.

It is related. 10 Studies have shown that current technologies hinder visually impaired individuals' access to mobile devices. Primarily voice-activated screen readers, constant vibration feedback, and dynamic Braille displays. It is observed that they are grouped under three main categories: voice screen reader systems, It conveys the text and menu content on the screen to the user through synthetic voice synthesis, and this 15 systems in crowded environments, public transportation, or where privacy is important In public areas, the sound emitted from the device can be heard by people in the vicinity. due to the unauthorized use of the user's private information, message content, or personal data This leads to the disclosure of personal information and creates a serious privacy issue. Privacy In cases where the use of voice screen readers is restricted due to concerns, visually impaired 20 Users' access to their devices is significantly restricted or completely blocked. Dynamic Braille displays, on the other hand, use electronically controlled rising pins or similar devices. It is possible to physically create Braille characters through raised elements, The systems display Braille characters at a fixed height or a fixed frequency, depending on the content of the text being read. It produces a rigid and unchanging vibration profile; the user's individual tactile perception 25 according to its characteristics, finger sensitivity, reading speed, or the force of pressure it applies It does not make any adaptations. However, tactile feedback is available among visually impaired users. perception thresholds, fingertip sensitivity, Braille reading speed, and preferred braille height. There are significant individual differences in this regard; these differences are not limited by fixed parameters. The current dynamic Braille displays are not easily readable by some users, 30 This leads some users to perceive it as insufficient or excessive. Low For a user with tactile sensitivity, fixed and low-height Braille dots are sufficient. While it doesn't provide any visual perception, the same raised height is uncomfortable for a highly sensitive user. This can be distracting or slow down reading speed. Similarly, user finger contact The failure to detect the pressure force applied during this process or any adaptation of this data 35 not being used in the process, existing systems are completely passive against user behavior. This leads to it remaining stagnant and failing to offer a personalized access experience. Furthermore, 11 Current dynamic Braille displays detect the position of the user's finger on the surface or Because it does not include a system that detects which area it is in contact with, it can touch the entire surface or a large area. Creating a raised area leads to unnecessary energy consumption and a physically complex tactile experience. This leads to the creation of this environment. Another significant shortcoming in current technologies is... a 5 that takes into account the user's environmental conditions and privacy requirements The access mode is the absence of a switching mechanism; the user is in a crowded environment. When you want to turn off the voice screen reader due to privacy concerns, existing systems do so automatically. It does not switch to tactile Braille mode and this switch must be done manually. This needs to be done, especially for those who do not have developed Braille reading skills or who need to use a fast mode. This creates an accessibility challenge for users who cannot make the transition. The ambient noise level is 10. headphone connection status, location information, or user-defined privacy settings Parameters such as preferences are not taken into account in existing accessibility systems, The biggest obstacle to a context-sensitive, intelligent, and autonomous access experience for the user.

This allows the visually impaired to... privacy, personalization, energy efficiency and context in individuals' access to mobile devices From an adaptability perspective, it is a holistic and technological approach unlike any existing technology. A solution is offered. 35 12 Ultimately, the problems mentioned above, which cannot be solved with the current technology, are related to the technical aspects. This has made it necessary to make an innovation in the field.

The changes are implemented in the access format 15 without requiring any manual intervention from the user. This involves adapting it to environmental conditions, thus improving Braille reading skills in particular. Accessibility is being facilitated for users who are not advanced in their field or who cannot switch modes quickly. Another aim of the invention is to learn the user's reading behavior during use, thereby improving accessibility. The goal is to provide a system that continuously improves its settings. With the learning user behavior module, 20 The user's reading speed, pressure habits, and preferences are analyzed over time, and this Based on the data, access settings will be automatically optimized for subsequent uses. This ensures that the quality of user-specific customization improves as the system is used, and is long-lasting. This provides a more efficient access experience in the long run.
