Database is vastly growing and improving our way of living with keeping inventory counts for major businesses or helping doctors keep track of patients. While this is a significant impact on our modern ways of living, database is being used more to implement with the disabled and the elderly. Just like how the internet has to be compatible with all kinds of users from around the world, database for the future is definitely making an impact for all. In order to show the future designs of database affecting the disabled and elderly, there are three areas that will be discussed including teaching database to the visually impaired, using database to understand speech for people with special needs, and using database to work with elderly on improving their ways of living. Each of these topics are designs that should be implemented in the future of the world as we are growing.
Database modeling is quite a challenge to learn as a class subject, but one teacher managed to create a design to teach her visually impaired student. Her challenge was figuring a way to demonstrate the database modeling, so she decided to use a tactile method rather than an auditory one (Brookshire, 2006). The materials used were index cards representing the rectangles, plastic strips, a cardboard as a frame for the diagram, and pushpins to represent cardinality (Brookshire, 2006). Definitely this method allows people to understand how to create the relationship tables with entities and cardinalities. Just because a person has a disability, doesn’t mean the person cannot learn like normal students. At the end of the class, the student successfully demonstrated the method worked and was as equivalent with students not visually impaired.
Aside from using a different technique to help someone with a disability, database functionally is used to understand speech for people with special needs. Elderly and speech impaired people have a trouble with understanding speech related situations like knowing different emotions conveyed (Iida, Yasumura, Campbell 1998). The technique is creating a corpus of emotional speech that uses frequency from a user when they express their emotion and stores it in a database to recognize each person’s frequency pattern (Iida, Yasurmura, Campbell 1998). The frequency results were astonishing stating that sad: 40Hz, joy: 53 Hz, anger: 57 Hz and the pauses for sad were longer than joy and anger (Iida, Yasurmura, Campbell 1998). The higher it was showed more anger, the lower it was showed sadness and being just right was the way to measure joy. As a database, it will be able to remember this from the user intending to use this speech recognition for emotions. The user with any disability or elderly can now convey their emotions to their intended audience without having any miscommunications.
Database helps simplifies elderly because many people from the 20th century are becoming an aged society. Technology is becoming more advanced than ever even kids are able to understand how to use complicated devices, but the aging society is having more difficulty to learn how to use them. The process being used contains three key ingredients using perception, followed by recognition and then operation to create a system for adults to understand new devices (Ishimoto, Sawashima, Yoshioka 2002). The data being collected is the user’s life eyesight, sound, hearing ability, memory, attentiveness, finger size, skillfulness, and how easy it is to understand and then creating a way where the user can use the product in a simplified manner (Ishimoto, Sawashima, Yoshioka 2002). This data can be used to create devices that appeal to elderly with using the data interpreted and used in software to adjust devices toward all the individuals.
In conclusion there is a huge factor with database with the elderly and disabled. Database is useful amongst everyone and it provides useful methods for the people in need and it plays a role with how it is being taught to students too. By understanding every individual and their need, there can be a world where everyone can learn despite any handicap or age. There can be a world where there shouldn’t be any labels of any individual despite their condition with the use of database technology.
