We present ZeRONE, a new indoor drone that does not use rotating blades for propulsion. The proposed device is a helium blimp type drone that uses the wind generated by the ultrasonic vibration of piezo elements for propulsion. Compared to normal drones with rotating propellers, the drone is much safer ...

We propose to equip smartphone-based HMDs (SbHMDs) with an additional touch pad. SbHMDs are a low cost approach to allowing users to experience virtual reality (VR). Current SbHMDs, however, provide poor input functionality and sometimes external devices are necessary to enhance the VR experience. Our proposal uses frustrated total internal ...

We present CamTrackPoint, a new input interface that can be controlled by finger gestures captured by front or rear cameras of a mobile device. CamTrackPoint mounts a 3D-printed ring on the camera's bezel, and it senses the movements of the user's finger by tracking the light passed through the finger. ...

Virtual reality (VR) using a head-mounted display (HMD) have been rapidly becoming popular. Lots of HMD products and various VR applications such as games, training tools and communication services have been released in recent years. However, there is a well-known problem that the user's face is covered by the HMD ...

We present a low-cost tracking technique for mobile virtual reality (VR) head-mounted displays (HMDs) that uses retro-reflective markers.Our technique allows the built-in cameras of existing smartphones to track real objects even if they are moving rapidly. The user simply attaches retro-reflective markers to the objects or creates unique objects (easily ...

We show ExtensionClip, a system that offers back-of-device touch interaction for a cardboard head-mounted display; it links the back of the smartphone to its touchscreen to greatly enhance the touch input area and usability. ExtensionClip sandwiches the smartphone between two magnets; the front magnet, which tracks the position of the ...

Touch sensing with multiple electrodes allows expressive touch interactions. The adaptability and flexibility of the sensor are important in efficiently prototyping touch based systems. The proposed technique uses capacitive touch sensing and simplifies the connections as the electrodes are connected in series via capacitors and the interface circuit is connected ...

This paper proposes a new approach to enhancing interaction with general applications on smartphones. Physical objects held on back surface of the smartphone, which can be captured by the rear camera with a mirror, work as input devices or controllers. It does not require any additional electronic devices but offers ...

Virtual reality (VR) using head-mounted displays (HMDs) is becoming popular. Smartphone-based HMDs (SbHMDs) are so low cost that users can easily experience VR. Unfortunately, their input modality is quite limited. We propose a real-time eye tracking technique that uses the built-in front facing camera to capture the user's eye. It ...

Head-mounted displays are rapidly becoming popular. Field-of-view is one of the key parameters of head-mounted displays, because a wider field-of-view gives higher presence and immersion in the virtual environment. However, wider field-of-view often increase device cost and weight because it needs complicated optics or expensive modules such as multi high-resolution ...

Depth sensing cameras that can acquire RGB and depth information are being widely used. They can expand and enhance various camera-based applications and are cheap but strong tools for computer human interaction. RGB and depth sensing cameras have quite different key parameters, such as exposure time. We focus on the ...
