RemoAct is a wearable depth sensing and projection system that enables interaction on many surfaces. It makes interaction with the environment more intuitive through sharing and sending data with surrounding devices by applying certain gestures. This system offers a mobile and intuitive solution for interacting using a projected surface on habitual flat surfaces. Every user has their public and private areas, where the user can create tiles on the fly and share it with others and these public tiles are shown to other users through augmented reality. Interaction is made through hand gestures, finger tracking and hand tracking. This gives the user more freedom in movement. Different experiments were conducted to calculate the accuracy and RemoAct ran against different conventional methods to compare its accuracy, time and user experience. RemoAct takes less time for two users to draw one chart. As the system enables the users to work simultaneously, it reduces the needed time, short compared to successive drawing. For gesture recognition, accuracy reached 90-95\%. Object recognition and face identification accuracy varied with the variation of light.

Abstract-In this paper we present an intuitive interaction technique for everyday objects. We propose a system that allows the user to interact with everyday objects, and use them to make smart scenarios. We enrich the objects with a portable projected interface that is supported by 3D accelerometer in order to build novel user object interaction scenarios. Moreover, we present double crossing as an interaction technique for manipulating finger interface. We conducted experiment to test the applicability of the proposed system with different applications. Our results showed that the proposed system has a lot of potentials to enrich different domains of applications like object data storage, education Montessori cubes and smart shopping goods.Index Terms-Object gestures, handheld projector, ubiquitous environments and portable interface interaction.

“…Researchers have explored interactions facilitated by body-worn projection systems (e.g., Blasko et al [2005] and Mistry et al [2009]), projectors integrated in phones and mobile computers (e.g., Hang et al [2008] and Kane et al [2009]), handheld and manually steered projectors (e.g., Cao et al [2007], Willis et al [2011], Molyneaux et al [2012], and Schmidt et al [2012]), and always-on projection sources situated in the user's environment [Huber et al 2012]. These works have in common that they embrace projection as a personal technology that provides users directly with novel ways of control and expression (for a survey of input and output concepts, see Rukzio et al [2012]).…”

Sensors, processors, and radios can be integrated invisibly into objects to make them smart and sensitive to user interaction, but feedback is often limited to beeps, blinks, or buzzes. We propose to redress this input-output imbalance by augmentation of smart objects with projected displays, that-unlike physical displays-allow seamless integration with the natural appearance of an object. In this article, we investigate how, in a ubiquitous computing world, smart objects can acquire and control a projection. We consider that projectors and cameras are ubiquitous in the environment, and we develop a novel conception and system that enables smart objects to spontaneously associate with projector-camera systems for cooperative augmentation. Projector-camera systems are conceived as generic, supporting standard computer vision methods for different appearance cues, and smart objects provide a model of their appearance for method selection at runtime, as well as sensor observations to constrain the visual detection process. Cooperative detection results in accurate location and pose of the object, which is then tracked for visual augmentation in response to display requests by the smart object. In this article, we define the conceptual framework underlying our approach; report on computer vision experiments that give original insight into natural appearance-based detection of everyday objects; show how object sensing can be used to increase speed and robustness of visual detection; describe and evaluate a fully implemented system; and describe two smart object applications to illustrate the system's cooperative augmentation process and the embodied interactions it enables with smart objects.
