Customers wanting a portable full-size keyboard might be in luck with the LG Rolly Keyboard (KBB-700), a self-descriptive device users can roll up into a "stick" for easy carrying in pockets or bags.

The Rolly Keyboard features a 17mm key pitch (most desktop keyboards have 18mm pitch) with "satisfying" tactile feedback. Construction is in polycarbonate and ABS plastic, and a pair of foldable arms smartphones and tablets in an upright position.

A company named Sensel presents what it claims is the first "pressure-sensitive multi-touch input device"-- the Morph, a device looking a bit like a giant version the Force Touch trackpad inside the latest Apple MacBooks.

The Morph carries 20000 pressure sensors allowing to detect and measure even the slightest of touches. It is non-capacitive, allowing one to use it with objects such as a paintbrush as well as their fingers.

Another interesting Morph features is Overlays-- thin and flexible sheets of material adding an extra layer of tactile feedback to the morph. Overlays can transform what is essentially an oversized trackpad into other peripherals, such as a QWERTY keyboard, piano keyboard, DJ controller or drum pad, among others. Magnetic codes allow the Morph to detect the the Overlay in place, and to automatically switch (or rather, "morph") to the required input modes.

Microsoft Applied Science presents prototype of an interesting tablet accessory-- the DisplayCover, a keyboard cover featuring an embedded eInk touchscreen handling app shortcuts and touch gestures.

As Microsoft puts it, tablets have admittedly limited screen sizes, and as such the addition of a display to the keyboard extends available display real estate. Thus the DisplayCover has a 1280x305 resolution touchscreen extending the screen area of a tablet with a 10.6-inch display by up to 8%.

Scientist at the Max Planck Institute and Saarland University reveal a means to turn the human body into a mobile device controller-- the iSkin, a sensor one can put on different body parts, such as fingers, forearms and even behind the ears.

The iSkin consists of biocompatible silicone rubber (specifically polydimethylsiloxane, aka PDMS) and conductive carbon black powder. It carries multiple pressure-sensitive sensors and is flexible enough to detect input pressure even when stretched by up to 30% or bent at a radius of 0.5cm.

So far the team has built prototypes in multiple shapes and sizes handling tasks such as answering calls alls, playing music and volume control. Another take on the technology involves a roll-up keyboard for smartwatch use.
