The article addresses the problem of intersemiotic translation: translating images into words. The first part deals with the issue of image hermeneutics. Following this, eye tracking research is briefly described and museum audio description for the blind and visually impaired is introduced. A case study of Self-portrait of Dora Maar is carried out, highlighting the importance of sight in the artist’s work. The text tries to answer the following questions: Who and using which techniques and strategies should translate images into words for recipients with visual disabilities, so that the translation is satisfactory and adapted to their perception? How to provide a visually impaired person with an aesthetic experience without imposing our own perception of the image on them?

The Ideal

One of the ideal public transportation facilities for the visually impaired in daily activities is trains. To be used at maximum, there is a need for communicative media to support the independence of orientation and mobility for the visually impaired in the train station. The media plays a role in supporting visually impaired individuals to know where they are, where to go, and how to reach the destination. The previous result regarding visually impaired ability to identify pictorial form which is designed with Primadi Tabrani’s ancient visual language semiotic approach shows a great opportunity for a pictogram to be the solution. However, the challenge is how to make the visually impaired person understand the meaning description that has been designed into tactile pictogram by touch. Basic consideration in designing process is the clarity of visual form when being touched, which is influenced by the way the shape is drawn and the tactile height

Further Development

The rehabilitation of a visually impaired person (VIP) is a systematic process where the person is provided with tools that allow them to deal with the impairment to achieve personal autonomy and independence, such as training for the use of the long cane as a tool for orientation and mobility (O&M). This process must be trained personally by specialists, leading to a limitation of human, technological and structural resources in some regions, especially those with economical narrow circumstances. A system to obtain information about the motion of the long cane and the leg using low-cost inertial sensors was developed to provide an overview of quantitative parameters such as sweeping coverage and gait analysis, that are currently visually analyzed during rehabilitation. The system was tested with 10 blindfolded volunteers in laboratory conditions following constant contact, two points touch, and three points touch travel techniques. The results indicate that the quantification system is reliable for measuring grip rotation, safety zone, sweeping amplitude and hand position using orientation angles with an accuracy of around 97.62%. However, a new method or an improvement of hardware must be developed to improve gait parameters’ measurements, since the step length measurement presented a mean accuracy of 94.62%. The system requires further development to be used as an aid in the rehabilitation process of the VIP. Now, it is a simple and low-cost technological aid that has the potential to improve the current practice of O&M.

Visually Impaired Persons

Many visually impaired individuals are found to be too passive or too aggressive in their social interactions. Lack of assertive behavior is related to the concept of learned helplessness. Components of assertive behavior are described with suggestions for enabling the visually impaired person to develop these skills. The underlying concepts of assertion training are explained along with specific techniques to be utilized in the school or rehabilitative setting. With a structured intervention resulting in improved assertiveness skills, blind or partially sighted individuals can increase their effectiveness in communicating with others and can feel more in control of their lives.
