To reduce traffic accidents at night driving, we introduce an augmented reality system using head-up display (HUD) in a vehicle and discuss the effectiveness and usefulness of the proposed system with representation strategy. The proposed system embraces recognition of dynamic object by radar-vision fusion, forward collision warning by threat assessment, and representation strategy using HUD. For...
A vehicle augmented reality system provides the warning, safety and route information which are registered on the real car or road or lane at the driver's range of vision for safety and convenience. This system helps the driver to drive safely by enhancing the perception of the driver. We have developed the vehicle augmented reality system which provides the forward situation awareness service and...
This study is to ensure the effects of an augmented-reality head-up display (AR-HUD) system on the perception of precautionary traffic situation. We performed the experiment in order to collect the drivers' response time as the perception on the objective precautionary situation. And the Driving Behavior Determinants questionnaire was used to collect the driver's psychological characteristics. As...
In this paper, we introduce a vehicle augmented reality (AR) system to present information of driving situation awareness in a vehicle. Today, manufacturers related with vehicles have been pointing to AR as a next-generation visualization technology for in-car driving displays. Such in-vehicle AR-based display systems are helpful in reducing driver distractions, thereby increasing driver safety, and...
Collision safety between humans and robots has drawn much attention because service robots are increasingly being used in human environments. The design of a service robot usually requires reliable collision analysis based on appropriate safety criterion. Previous safety criteria are too restrictive or generous with respect to collision injury. This paper proposes a new safety criterion for physical...
A safe robot arm can be achieved by either passive or active compliance. The passive compliance systems composed of purely mechanical elements often provide faster and more reliable responses for dynamic collision than the active ones involving sensors and actuators. Since both positioning accuracy and collision safety are important, a robot arm should exhibit very low stiffness when subjected to...
