We present further developments of our system that allows direction interaction between a camera-equipped hand-held device and a remote display. The essence of this system is the ability to estimate a planar projectivity between the remote display and the displayed image of that display on the handheld device. We describe how to achieve this by matching scale invariant SURF features across the ...

We describe a device that can display very high intensity (up to 400,000 cd/m2), high-resolution visual stimuli. The device is inexpensive, is easily controlled by a conventional computer and video card, and can be calibrated for use in vision research or clinical applications. The display is capable of presenting highly saturated, near spectral colors. Unlike Maxwellian view optical systems, o...

Electro-tactile display has simple mechanical structure and it can present tactile stimulus. However, electro-tactile display lacks of feedback corresponding to touching motion. In this research, we developed a device that combines an electro-tactile display and pressure distribution sensor. The device not only solves problem of unnatural electrical sensation, but also enables expression of hap...

San Lam(*) and Herbert De Smet(*,**) *Ghent University, department ELIS (TFCG Microsystems), Gent, Belgium ** IMEC vzw, division INTEC, Gent, Belgium 1. Abstract This paper investigates the frame resolution scalability of wavelet based passive matrix display addressing for mobile terminals. The wavelet-transform and the considered video codec architecture are both inherently resolution-scalable...

Dual-functioning displays, which can simultaneously transmit and receive information and energy through visible light, would enable enhanced user interfaces and device-to-device interactivity. We demonstrate that double heterojunctions designed into colloidal semiconductor nanorods allow both efficient photocurrent generation through a photovoltaic response and electroluminescence within a sing...

A high ambient-contrast-ratio (A-CR) and large aperture-ratio display is conceptually demonstrated and experimentally validated by stacking a normally black reflective liquid crystal display (NB-RLCD) and an organic light-emitting device (OLED). Such a tandem device can be switched between the NB-RLCD mode and the OLED mode under bright and dark ambient light, respectively. The normally black c...

Documents generated for different devices must each take into account the display constraints of the device for which it is tailored. This is especially true in the case of mobile devices, which typically have a small screen size constraint. In this paper, we present a platform for dynamically generating documents, tailoring the presentation for the user’s choice of display device, be it web br...

In this paper, we describe the AR Mask, a novel handheld Augmented Reality (AR) input and display device that not only provides support for a full range of traditional interaction techniques, but also facilitates new metaphors. Unlike other AR display and input technologies, our device consolidates input and output within a single piece of hardware. We demonstrate how this design provides a clo...

We describe the design and performance of a bright, full-color, video-input display monitor that can produce image luminances as high as 50,000 cd/m2 for images 15 x 10 deg in size. We have constructed this device by rearranging the components of a commercially available projection television. Our display device allows an experimenter to evaluate human visual responses to complex spectro-spatio...

Recently, according to the advanced hardware technology, the price of sensors in HMD (Head Mounted Display) is getting cheaper and calculation speed in smartphone is fast enough to express a plausible virtual reality. Users wear the HMD device on their head and it shows the virtual scenes in front of users. Users can enjoy a wide display without any restrictions in space. Based on this device, ...
