This lesson serves as an introduction to creating mobile augmented reality applications. Augmented reality (AR) can be defined as the overlaying of digital content (images, video, text, sound, etc.) onto physical objects or locations, and it is typically experienced by looking through the camera lens of an electronic device such as a smartphone, tablet, or optical head-mounted display.

Touch Interaction

This paper proposes an interaction method to conveniently manipulate a virtual object by combining touch interaction and head movements for a head-mounted display (HMD), which provides mobile augmented reality (AR). A user can conveniently manipulate a virtual object with touch interaction recognized from the inertial measurement unit (IMU) attached to the index finger’s nail and head movements tracked by the IMU embedded in the HMD. We design two interactions that combine touch and head movements, to manipulate a virtual object on a mobile HMD. Each designed interaction method manipulates virtual objects by controlling ray casting and adjusting widgets. To evaluate the usability of the designed interaction methods, a user evaluation is performed in comparison with the hand interaction using Hololens. As a result, the designed interaction method receives positive feedback that virtual objects can be manipulated easily in a mobile AR environment.

Mobile Ar

Sophisticated vehicle ergonomics are a relevant factor for the success of a new vehicle model. To support the evaluation of vehicle ergonomics we have developed a mobile Augmented Reality (AR) testing platform in cooperation with Volkswagen commercial vehicle. The mobile AR-based testing platform consists of a Volkswagen Multivan, where roof, pillars, and dashboard have been removed. The missing parts are replaced by new virtual parts. A head mounted display presents the virtual parts to the user of the mobile AR testing platform, that way, enabling visibility analyses. The user can also interact with the virtual components of the vehicle to perform reachability analyses. To support these analyses the user’s hands are recognized by the system. In this paper we introduce a method for tracking the user’s hands in a mobile AR testing platform. Using image processing the hands of the user are detected by checking for the skin color or the color of a glove the user wears. From image processing data we compute the position of the user’s real hand and potential collisions between the hand and virtual vehicle components. We also utilize results from collision detection for the interaction with the virtual objects.
