Electrosmog is invisible, and we rely on detectors which show level of electrosmog in a abstract warning such as numbers. Our system is able to detect electrosmog level from number of Wi-Fi networks, connected cellular towers and strengths, and show in an intuitive representation by blurring the vision of the users wearing a Head-Mounted Display (HMD). The HMD displays in real-time the users' augmented surrounding environment with blurriness, as though the electrosmog actually clouds the environment. For demonstration, participants can walk in a video-see-through HMD and observe vision gradually blurred while approaching our prepared dense wireless network.

We have investigated how to adapt such HMD as Oculus Rift for an outdoor AR ski slope. Rather than setting physical obstacles such as poles, our system employs AR to render dynamic obstacles by different means. During the demo, skiers will wear a video-see-through HMD while trying to ski on a real ski slope where AR obstacles are rendered.

Previous studies indicated simultaneous music listening and performance is difficult for non-musicians, and that visual support for the task might be helpful. This paper presents results from a preliminary user study conducted to evaluate the effect of visual feedback on a musical tracking task. Participants generated a musical signal by manipulating a hand-held device with two dimensions of control over two parameters, pitch and density of note events, and were given the task of following a target pattern as closely as possible. The target pattern was a machine-generated musical signal comprising of variation over the same two parameters. Visual feedback provided participants with information about the control parameters of the musical signal generated by the machine. We measured the task performance under different visual feedback strategies. Results show that single parameter visualizations tend to improve the tracking performance with respect to the visualized parameter, but not the non-visualized parameter. Visualizing two independent parameters simultaneously decreases performance in both dimensions.
