3. Reminder BodyPointer will give ability to people with physical
impairments to control the computer.
The project will be based on MindDesktop project,
which use Epoc headset in order to detect signals from
face movement and thought.
In addition to that signals, BodyPointer will interact with the Body Sensors System, called ProComp Infiniti, which covers a full range of objective physiological signals used in biofeedback.
With those two devices, the system can measure bodily and face signals and capture data in real time.

5. Prototype
The prototype is mainly related to the new functionality that is added by the body sensors.
In order to prove the concept, we applied the following tasks:
Connect to encoder
Get signals from encoder
Detect the body action preformed
Detect the sensor which sent the signal
Translate the body action into UI operation
Execute and use basic applications in Windows OS, using a
virtual keyboard

6. Prototype
The demo demonstrates navigation and execution of Windows applications, by putting body sensors on 3 different locations:
Respiration sensor – e.g. on the right hand
Respiration sensor – e.g. on the stomach
EMG sensor – e.g. on the left hand
Those locations define 3 basic actions: Left/Right, Up/Down and Click.
For example, by bending the left hand, the marker of the application will move up.

9. Prototype
While proving the concept with BodyPointer Demo we also focused on the following tasks:
Get familiar with the devices
Learn MindDesktop project
Integration between Procomp Infiniti and Epoc Headset
Integration between MindDesktop code and BodyPointer Demo
Analyze the main problems at MindDesktop project and suggest
solutions

10. Conclusions
Each user has different range of signal’s values that detected by
the sensors in each body location.
Thus, it is necessary to define accurate training phase that
promise reliable system.
Synchronizing between more than one body action simultaneous
is needed.
Testing the body actions from the perspective of disabled users
is essential.
