ÜberPad II
Posted in netbook | March 6, 2009 2am

The Überpad is a low-powered tablet PC equipped with many sheets of e-paper, each of which can be removed, replaced or exchanged with sheets supporting more advanced capabilities such as colour, stylus input, touch sensitivity or even scanning.

The primary display (LED, OLED, LCD or whatever) is both used as a normal display and as a means of input, either by touch or by the use of a tilt and pressure sensitive stylus equipped with an eraser and a side switch or two. The tilt sensitivity is required for the stylus's tip to be accurately determined from the position of its magnetic pickup. The side switch is to perform the function usually assigned to the right mouse button on a desktop PC. When not in use, the stylus is stowed away in the "spine" of the book in the manner of a push-to-eject memory card.

Supporting Stylus IDs (as Wacom tablets do) would be a great bonus as it would allow two-player games to be easily played over a café table. For artist types, it would also allow painting tools to be assigned to different styluses.

Sheets of e-paper of equal capability are made identically and are addressed in a daisy chain from the electrodes on the book's back cover. Each sheet receives the address expressed by the electrodes on its lower surface, increments the address by one and expresses the incremented address on the electrodes on its upper surface for the sheet stacked on top of it. Any sheet knows its being addressed when zero, say, appears on the address bus. Ten bits should be enough. (This addressing mechanism is a more efficient form of the method used to address up to four Amiga floppy disc drives. Each drive in the chain rotates the four select wires by one.)

The electrodes will need to be resistant to dirt. Either inductive or capacitive coupling will do.

The sheets could be clamped in the manner or a three-ring binder. For more flexibility, the sheets could be fitted with ridges and grooves (to aid alignment) and pressed together and to the back cover by a clamp. Pages in the middle could then be removed or inserted directly.

A significant proportion of the time the Überpad would likely be used would be spent reading pages of text and thumbing albums of photos or drawings. Therefore it would make sense for the primary display (on the front cover) to be turned off when the book is open. Since e-paper requires no power to maintain a static display, battery life would be no problem.

Since being able to browsing the web from anywhere is so useful. a wi-fi antenna is provided. It is stowed in a similar manner to the stylus. A fully internal antenna might work, but efficiency (and therefore battery life) may be a concern.

The Überpad is designed for artist types to sketch, scribble notes and to annotate essays. With such a device, they can look especially cool while doing it, wherever they are.

Obfusocculter
Posted in netbook | November 4, 2008 1am

This device allows a user to enter a password in a public place wothout fear of anyone or anything looking over their shoulder watching the password being entered. The device produces an image that is visible with a few degrees from the axis normal to the display. Outside of the nominal viewing renge, a guidance image is displayed to direct the user to move his or head to the proper viewing position.

The private display can be used in a variety of ways, depensing on the application. One way is to display a jumbled array of numbers (or letters) that are mapped to the keys of the numeric cluster, say. Each time a character is entered, the display presents a new arrangement.

Another way is to (a) draw a conventional grid of characters in a manner of a high-score name entry interface of a coin-operated video game and (b) have the user select a character by moving graphical pointer or by manipulating the grid of characters beneath a static focus point. The focus, which begins in a random position for each character to be entred, may be moved in a wrap-around fashion with a mouse, keyboard. tablet or touchpad,

In principle, this device could work at the operating system level. No explicit support from any application is required.

Überpad
Posted in netbook | October 31, 2008 11pm

The Überbook allows reading (and thumbing through) of photo albums or pages of text. The hard front cover is used both as a colour display and a means of input via the pressure-sensitive stylus. The device is primary for artist types to sketch, scribble notes, annotate essays and to surf the web.
