I am co-organising the CHI 2012 Workshop on Designing and Evaluating Text Entry Methods. If you are doing research related to text entry we want to hear about it! The format will be a friendly series of panel discussions on timely topics in text entry. Submission deadline is January 13, 2012. The workshop will be held on May 5, 2012 in Austin, Texas in conjunction with CHI 2012.

The University of St Andrews writes about our work on
using crowdsourcing and online web sources to create
better statistical language models for AAC devices. Twitter: it's good to talk.

We have released our Enron
mobile email dataset, a subset of the Enron
email dataset. It consists of genuine
mobile emails Enron executives wrote using their
BlackBerry devices. It is primarily intended to
increase the internal and external validity in
mobile text entry experiments. We have
added useful metadata for this purpose, such as sentence
memorability, full-sized keyboard entry and error
rates, and sentence category (business, personal,
Enron-specific). For further details see our MobileHCI

We have released the source code
for our new continuous recognition algorithm for
pen strokes and touch-screen gestures. It
enables interactive systems to eagerly process users'
input before users have completed their input
gestures. We used this algorithm to design two new visualisations. For further details see our SBIM 2011 paper.

Augmented and Alternative Communication (AAC) devices enable users with certain communication difficulties to engage in conversations, typically via a predictive text input interface. However, a problem is the lack of representative corpora, and as a result, well-performing language models. To help this situation we have just released an AAC corpus and associated language models for conversational language modelling. For further details see our EMNLP 2011 paper.

A free demonstrator of ShapeWriter is available for iPhone and iPhone Touch via the Apple Appstore! Click this link to reach the download page via iTunes.
This version uses the mobile phone optimized version of the ShapeWriter recognizer I developed and implemented when I was working Beijing. It was challenging since recognition accuracy had to be the same as the full-scale Tablet PC recognizer I developed at Linköping University and IBM Almaden Research Center in 2002-2003, while at the same time both recognition latency and memory space requirements needed to be trimmed by an order of magnitude (this paper presents the original ShapeWriter recognizer). The lexicon in the application has 60,000 words in it. So far there are 77 user reviews and an average score of 4/5. The majority of complaints stem from a couple of unfortunate bugs in the initial "writing pad" application part of the demonstrator. These bugs were fixed in V1.0.1. Try it!
- May 9, 2008 ShapeWriter, Inc. is one of the winners in the Google Android Developer Challenge Part I! Our entry featured a full-blown ShapeWriter recognizer capable of recognizing 60,000 words (U.S. English) in realtime on the Android Emulator. All our code was written in Java using the Google Android SDK.
