Development of an inexpensive Augmented Reality (AR) headset

We outline our work in developing an Augmented Reality (AR) headset with low purchase and maintenance costs. Similar to Google Cardboard, the headset uses a smartphone to provide the compute power, connectivity and display. Unlike Google Cardboard, our headset does not block the user's view of the world and is therefore suitable for AR applications. The headset uses the Pepper's Ghost illusion to display images from the phone's screen via a transparent sheet located in front of the user's eyes. During a pilot study, we confirmed that the headset is effective in settings with low to medium levels of ambient illumination: in these conditions we demonstrated the effectiveness of using a mobile phone's standard screen brightness settings to present a range of photos, 3D images, short texts and shapes

A Toolkit for Exploring Augmented Reality Through Construction with Children

International audienceAugmented Reality begins to be widely mainstream among children, due to some interactive successes in video games and social networks. Based on this interest, we present CartonEd, an open and complete toolkit suitable for children dedicated to the construction of an augmented reality headset device. The toolkit let the children play and explore augmented reality with and beyond handheld devices. Inspired by the Do-It-Yourself movement, the toolkit includes different components such as blueprints, tutorials, videos, mobile apps, a software development kit and an official website. Among the mobile applications, one is implemented to guide the children through the construction process while experiencing augmented reality. To validate our solution (in particular the construction process and the guiding app) and understand its effect on children in regard to their relation to the augmented reality, we conducted four construction sessions. Our study examines the usability of the guiding app and the construction process. We report in this paper the main components of the CartonEd toolkit and the results of an evaluation among 57 children and teenagers (ages 8-16), showing a positive outcome about their own constructed device (all functional), their feelings and wishes regarding the augmented reality

CARTON Project: Do-It-Yourself Approach to Turn a Smartphone into a Smart Eyewear

International audienceThis paper presents a tool to transform a smartphone into a smart eyewear, named "CARTON", following a Do-It-Yourself (DIY) approach. The hardware prototype is made with very simple materials and regular tools we could find anywhere. It also includes a Software Development Kit (SDK) with samples in order to easily adapt or develop new mobile app compatible with this kind of device. By providing everything open-source and open-hardware, we intend to solve the reachability of technologies related to smart eyewear and aim to accelerate research around it. Users experiments were conducted in which participants were asked to create, by themselves, the CARTON's hardware part and perform usability tests with their own creation. Qualitative user feedback and quantitative results prove that CARTON is functional and feasible by anyone, without specific skills
