2 2 Human Attention & Environment Selectively attending to one aspect of the environment Study of joint attention for communication on objects Human factors in the context of environments Study of attention, workload, memory, stress, emotion and decision making Study of wayfinding systems, marketing concepts, usability of user interfaces and products
3 3 Wearable Eye Tracking Glasses HD camera

5 5 Human Factors Analysis, User Modeling, and Simulation Wearable Multimodal Sensing User Interaction & Human Factors Analysis User Model Attention Model Simulation in 3D Model Statistical Analysis 3D model
6 6 Motivation 3D Gaze Estimation Understanding behavior in task specific ambiente Localise Real Human Gaze in the 3D environment Saliency map on attended infrastructure Vrvis, JR, AIT, 2006
7 7 Previous Work on 3D Attention Mapping Munn et al. [ETRA, 2008] Introduced monocular eye-tracking and triangulation of 2D gaze positions of subsequent key frames within the scene video of the eyetracking system. Reconstructed only single 3D points without the reference to a complete 3D model achieving angular error of 3.8 (our: 0.6 ) Voßkühler et al. [ECEM 2009], Pirri et al. [CVPR 2011] Requires special, not mass marketed stereo rig that is required in addition to a commercial eye-tracking device. The achieved accuracy indoor is 3.6 cm at 2 m distance to the target (our: 0.9 cm) at the same distance of our proposed workflow. No reference to 3D model
8 8 Workflow: Recovery of 3D Gaze & Semantics
9 9 3D Model Generation: RGB-D based Map Building Depth assocation by means of stereo calibration pointcloud Pose trajectory on ground plane
10 10 3D Model Generation: Methodology Fully automated 3D model generation Grabbing RGB-D images of environment with Kinect Performing depth based visual SLAM using both image and depth information [*] Reconstruction of sparse point cloud consisting of 3D feature points Each feature point is attached to a SIFT descriptor for robust data association during pose estimation Pose estimation using sliding window bundle adjustment while minimizing reprojection error and depth discrepancy using 2D-3D correspondences [*] K.

11 11 3D Model Generation: Loop Closing Loop closure detection through vocabulary tree search query frame potential loop closing candidates returned by the vocabulary tree Returns a probability for each image in the map/tree Geometr. consistency check delivers candidate frame Low memory and fast computation time
12 12 3D Model Generation: Dense Model For human attention analysis and realistic surface reconstruction, a dense environment model is constructed afterwards Using probabilistic occupancy grid mapping Every depth image is inserted into the voxel space Using pyramidal approach presented in [*] Real-time performance using GPU implementation Surface reconstruction is handled by standard marching cubes algorithm [**] [*] K.

13 13 Result: 3D Model
14 14 Image based Pose Estimation: Matching Process matching point cloud matching Results in pose for every ETG frame
15 15 Image based Pose Estimation [**] Estimate the user s pose within previously reconstructed area Sparse three-dimensional point cloud and its SIFT keypoints build the matching model ETG 2D image descriptors are matched against those in the 3D point cloud (global/local) Pose estimation through perspective n-point algorithm [*] RANSAC is used to eliminate matching outlier [*] Lepetit V., Moreno-Noguer F. and Fua P.: EPnP: An Accurate O(n) Solution to the PnP Problem, International Journal of Computer Vision, pp , [**] Santner, K., Paletta, L., Fritz, G., Mayer, H., Visual Recovery of Saliency Maps from Human Attention in 3D Environments, Proc. ICRA 2013.
16 16 Image based Pose Estimation: Issues? point cloud? 200 out of 2200 poses could not be estimated (~90% coverage)! less image feature points (textureless area)! rapid head movements (motion blur)
