E-tree is an in-home Energy Consumption Display (ECD), which the user can use as both stationary and portable device. We explored E-tree to help the user understand their energy consumption at the home. Project phase two included three goals. First, we implemented a wireless measurement device, which uses an Infrastructure Mediated Sensing (IMS) system attached to the home power breaker. E-tree...

Public electronic displays can be used as an advertising medium when space is a scarce resource, and it is desirable to expose many advertisements to as wide an audience as possible. Although the efficiency of such advertising systems can be improved if the display is aware of the identity and interests of the audience, this knowledge is difficult to acquire when users are not actively interact...

Autostereoscopic displays provide 3D perception without the need for special glasses or other head gear. Three basic technologies exist to make such displays: spatial multiplex, multi-projector and time-sequential. These can be used to make two types of useful device: two-view, head-tracked displays; and multi-view displays. The former tend to be single-viewer systems while the latter can suppo...

A method is proposed to facilitate visually-driven interactions between two devices, which we call the client, such as a mobile phone or personal digital assistant (PDA), which must be equipped with a camera, and the server, such as a personal computer (PC) or intelligent display. The technique that we describe here requires a camera on the client to view the display on the server, such that ei...

We have designed, and are in the process of building, a visualisation device, the Cub-e. The Cub-e consists of six TFT screens, arranged in a perspex cube, with a StrongARM processor and batteries inside. It is a multipurpose device with applications including teleconferencing, interaction with virtual worlds, and games.

This paper proposes a channel-independent inverse characterization process based on the GOG model for a display device. The CIEXYZ values for each of RGB channel can estimated from nine channel-independent interpolation TRCs (Tone Response Curves), and the result of this characterization method is better than that from conventional three channel-independent interpolation TRCs. However inverse c...

Today’s viewers consume video content from a variety of connected devices, including smart phones, tablets, notebooks, TVs, and PCs. This imposes significant challenges for managing video traffic efficiently to ensure an acceptable quality-of-experience (QoE) for the end users as the perceptual quality of video content strongly depends on the properties of the display device and the viewing con...

In the past, tactile displays were of one of two kinds: they were either shape displays, or relied on distributed vibrotactile stimulation. A tactile display device is described in this paper which is distinguished by the fact that it relies exclusively on lateral skin stretch stimulation. It is constructed from an array of 64 closely packed piezoelectric actuators connected to a membrane. The ...
