Handheld device as pointing device on computer systems

The disclosed is a system that employs the existing input capabilities of a handheld electronic portable device as alternative pointing devices for a computer. The main idea is the use of a software layer between those systems to make the input capabilities from the former device available to the computer system.

Handheld devices (eg: PDA, Palmtops, SmartPhones) are known to provide several functionalities to ease the data input and interaction with the user:

An user interface that allows easy pointing and/or drawing (e.g: touchscreens, pen-sensible screens).

Ability to establish network connections with external devices and exchange data with other computer systems.

The disclosed system provides several additional functionalities to users:

Enables the user to remotely operate the computer

Enables handfree drawings, using the input capabilities of the handheld device and specific softwares available only on the remote computer;

Low cost solution. Handheld devices are available for mass consumer market. This avoids the need of acquiring, installing and configuring additional specialized and expensive hardware like pen or tablets on the computer.

A handheld device is already customized with user preferences, and the user does not need to learn how to handle new pointing devices.

Practical examples of use of the invention:

Drawing pictures. The easiest way to draw pictures is using a pen, a well-established input device

for handhelds.

Writing documents. Simplifies formatting and moving text boxes around.

Slide show presentation. The presenter employs his/her handheld device as a remote mouse.

Network meetings with shared presentation. During a talk, the presenter may need to add hand


Instant messengers. Allows easily sending handwritten messages without need of a tablet.

On video or computer games. Allows other input base on hand drawing, opening new

opportunities for gaming experiences.

On virtual worlds. Allow user to leave customized, handwritten messages and drawings. Also,

creates new opportunities for interactions with elements from the virtual world.

On interactive devices (like interactive TV menus). An alternative pointing device to existing

remote control.

For example, when using Bluetooth, the security will be guaranteed by using PIN codes, for wi-fi by using WEP and WPA and for internet connections a SSL layer can be used.

Scenario 1: The user owns a handheld device that is able to communicate directly with a computer system. Examples (wired): USB cable, serial cable, firewire, etc. Examples (wireless): infrared, bluethooth.

Software is executed on the handheld device to capture the user input and to provide visual feedback for each user action. The software uses a protocol to sent these input to the computer system. Another software is executed on the computer system to translate the protocol to pointing events suppor...
