Depending on the size of thetangible interface, the computing resource restrictions and theresolution required, there are different technological alternativesfor multi-touch screens such as camera based systems, capacity,resistive or pressure sensing systems or LED based systems. Thispaper presents a different alternative to deploy medium to largesize multi-touch screens with low computational requirements fortracking the user movements based on the Near FieldCommunication NFC technology. The paper makes a review ofthe main related technologies to create medium to large sizemulti-touch screens identifying their pros and cons and proposes a different design based on NFC tags and mobile readers. Amulti-touch algorithm is designed and implemented+-

A Java based desktop application will receive the NFC tag IDs and perform gesture and shape identification of each of the hands of the users and consequently control the projection system. NFC is an intuitive way of mobile communication that has achieved high level of consumer appreciation.
NFC operates in three modes, namely, Tag emulation, Read-Write and Peerto-peer.
However only one mode can be manually selected and work with at a time [1].
J2ME is the Java platform used in order to develop NFC application for mobile phones in most of the pre-commercial devices.
J2ME includes, among other configurations, CLDC which is supported by MIDP profile. Pre-commercial SDK’s widely used for NFC applications are Nokia 6131 NFC SDK 1.1 and Series 40 Nokia 6212 NFC SDK.
Both SDKs support Eclipse and NetBeans IDEs but the former contains additional Java packages which are implemented as stubs whereas the latter contains NFC Manager [2]. Among the APIs needed for NFC application is the Contactless Communication API (JSR 257).
This supports tag emulation...
