Abstract: Systems and methods are provided for generating signature ambient sounds and maps thereof to assist in navigation based on a start location, a destination location, start time and average walking speed. The maps are generated by concatenating two or more of the signature ambient sounds and two or more of voice based navigation guidance. The signature ambient sounds for up to all location coordinate pairs in a map, for up to all time ranges and for up to all walking speed ranges are generated and tagged to the corresponding location coordinate pair, the corresponding time range and the corresponding average walking speed. The signature ambient sounds are generated by applying digital signal processing techniques on ambient sounds recorded by client devices, that are filtered and outlier removed.

Abstract: A computer implemented system and method for image based location specific password construction and authentication is provided. The system helps users to recognize the password in terms of objects in an image rather than recalling the alphanumeric passwords. A graph walk generator present in the system guides a user to take unique pictures/images/photographs from user's geographical location which helps the user to recognize password easily in future. The system helps in creating and maintaining a strong password by using pseudorandom image presenter. It also allows a user to aid his photographic memory to get authenticated to the system. Every user generates certain number of images by capturing images in vicinity and select objects from an image to create a password. A user authentication module present in the system then authenticates the user based on sequence of the objects within the captured image to provide one-time image based authentication.

Abstract translation: 提供了一种用于基于图像的位置特定密码构造和认证的计算机实现的系统和方法。 该系统帮助用户根据图像中的对象识别密码，而不是调用字母数字密码。 存在于系统中的图形行走发生器引导用户从用户的地理位置拍摄独特的照片/图像/照片，这有助于用户日后轻松识别密码。 该系统通过使用伪随机映像呈现器来帮助创建和维护强密码。 它还允许用户帮助他的照相存储器获得对系统的认证。 每个用户通过捕获附近的图像并从图像中选择对象以创建密码来生成一定数量的图像。 存在于系统中的用户认证模块然后基于拍摄图像内的对象的顺序对用户进行认证，以提供一次性基于图像的认证。

Abstract: The use of gestures are increasing frequently. Normally these gestures are disconnected with each other. Therefore, various methods have been used for creating the gestural language. The existing methods for creating gestural language is difficult to learn and lacks design aesthetics. A method and system for creating aesthetic design language using a plurality of gestures is provided. The system takes in to account of aesthetics of the generated form of gestures and the user's constraints of movement—degrees of freedom. The system is using a socio-techno system which aids the machine assisted creation of aesthetic language for gestural interactions. A grammar has also been defined for creating the gestural language based on the domain. In the final stage of the system, the grammar and the form symbols are chosen/selected/published to present the interaction language to the user.
