Paper Four: a Capacitive Touch Paper

Paper Four

Paper Four is a research project at FiberScience and Communications Network at Mid Sweden University, Sundsvall, Sweden. Sensing electrodes are printed on the paper using conductive ink. It is claimed that the printing process is done by normal inkjet printers.

Multi-touch... Are you sure?

Hand pressure map

Today, I read an Engadget post about another multi-touch enabled gadget. I don't want blame the concept but should point out that many people are confused when they are saying multi-touch. The Panasonic remote controller, at a first glance, doesn't have multi-touch sensor. It just has two touch pads in serial to emulate multi-touch zoom in/out gestures.

Actually, the term multi-touch now has two different meanings: 1) a system that detects multiple contact or pressure points simultaneously, and 2) a system that classifies gestures with two or more fingers (such as two finger pinching and rotation). Apple iPhone and MS Surface definitely have sensing systems to detect multiple touch points simultaneously. However, many other touch companies and gadgets, reportedly having multi-touch, just add software codes to classify more gesture inputs with standard single touch sensors.

As far as I know, only Cypress clearly defines differences between multi-touch sensors and multi-touch gestures in their TrueTouch solution page.

Laptop Makers Shy Away from Multitouch Technology


Objective opinion on multi-touch interfaces.

But there will be a "strong and unstoppable" trend towards a control interface for technology that is based on simple human gestures, rather than on indirect manipulation via physical objects such as a mouse, he predicts.

He says that revolution is three to five years off for mainstream business, but it's not too soon for business leaders to "suspend their natural scepticism" and start to think about how gestural computing might be used to address their organisations' most intractable user interface issues.

Leonardo, B., V. Cati, et al. (2006). TapTap: a haptic wearable for asynchronous distributed touch therapy. CHI '06 extended abstracts on Human factors in computing systems. Montreal, Quebec, Canada, ACM.

TapTap is a wearable haptic system that allows nurturing human touch to be recorded, broadcast and played back for emotional therapy. Haptic input/output modules in a convenient modular scarf provide affectionate touch that can be personalized. We present a working prototype informed by a pilot study.
