The study discussed the combination of audio and haptic interfaces, and concluded that they together more than complemented each other. This is something that we should make note of, if we want to create a game to which blind children can easily adapt.

VBGhost: a Braille-Based Educational Smartphone Game for Children
The authors discuss their newly developed game for smartphones, VBGhost, bases on the game ghost in which players take turns adding letters to a word fragment. The letters are entered in braille, with a 3 by 2 braille cell presented on the screen. Players can raise or lower these dots by double tapping on them. If a dot is raised and a player taps on it, the phone vibrates. The app also includes a high contrast menu, meaning that people with low vision can also read the interface.

Virtual Mobile Science Learning for Blind People
This paper discusses AudioNature, an audio-based interface for pocketPC. It is designed to assist in science learning. The device uses an audio interface to transmit information to the user, and takes input in the form of buttons and a touch screen. One striking feature of this method is that it enables the user to use while moving. Many devices for blind people, the author notes, are made to be used in a static position. Focusing on mobility will help blind people to freer in their movements, and will ultimately lead to better integration with society.

MathMelodies: Inclusive Design of a Didactic Game to Practice Mathematics
With the introduction of tablets in an educational environment, a gaming or entertaining atmosphere can be created in which children learn new concepts. However, these games are mostly visually oriented. This paper describes a game which teaches basic arithmetic through sound. Most of the exercises are read out loud, and also how to answer them is explained. To keep the user entertained, a variety of sounds are added, a rating system based on the number of errors made and a storyline is added. The authors describe that teachers have reacted enthusiastically to this game.

Game-based Learning: Latest Evidence and Future Directions
This article describes the exact nature of game-based learning, and lists the evidence to support commonly made claims about it. It describes in a more abstract manner the principles which go behind game-based learning, and the mechanics with which it tries to adhere to these. Interesting is the following conclusion: “Don’t try to divorce decontextualized components of a game (such as badges, scores or leaderboards) from the fictional context and rules of the game (the ‘mechanics’). Using badges and medals can work for certain simple tasks, but actual game-based learning will require using those techniques in the context of rule-sets and role-playing.”

The Today and Tomorrow of Braille Learning
This article mainly elaborates on the decreasing literacy for people using braille due to the use of modern technology. The motivation to learn braille has decreased. It highlighted the problems with existing technology and provided ways in which the situation can be improved. The article was mainly based on interviews with blind people.

Students' attitude towards the use of educational video games to develop competencies
As the study suggests, described in this paper, students' positive attitude towards the use of educative games cannot be taken for granted. Four students' characteristics (perceived relevance, perceived confidence, media affinity, and perceived self-efficacy) influence their attitude towards the games. Relevance is not related only to the content being learned but also to the way the content is taught. Confidence is an important motivational driver which can influence learners' persistence and accomplishment. Media affinity is how, in this case, important games are for the students. Self-efficacy refers to an individual's belief on his/her ability to achieve a desired outcome.

BraillePlay: Educational Smartphone Games for Blind Children
The conclusion of this article was that children were not easily motivated in playing a simple game for an extended amount of time. The article described four different games like hangman and ghost. For children learning braille these games proved difficult due to their limited vocabulary. The games where apps running on a smartphone. The article also names a few ways in which braille can be displayed on a smartphone.

Design and Usability of a Braille-based Mobile Audio game Environment
This article describes multiple games that could be implemented for educational purposes. The games use a GBraille keyboard, which is a way to allow a user to type in braille on their smartphone. The interviews with teachers expressed a concern with the keyboard. Using the keyboard gives a wrong impression of braille since real braille uses raised dots instead of vibrations.

TDraw: A Computer-Based Tactile Drawing Tool for Blind People
The article provides a lot of information on the theory that blind people have the ability to create a mental 3D model of the world around them. This leads to the belief that blind people can draw provided the tools for it and for that reason the research is about a computer tool that would allow blind people to do drawings and graphical work.

Designing Haptic Graphics for Mathematics: Towards Accessible Math Education for Blind Students
In this design project haptic technologies are explored to evaluate their ability to communicate graphical aids used in mathematics. Unfortunately, performance of haptic identification with such technologies was poor. It would simply take too long to haptically identify a line drawing, while accuracy would also decrease drastically with increased complexity of the line drawing. Therefore, a new method for creating tactile drawings on the fly has been sought in 3D printing methods.
