Evaluating user experience based on biometric data:
1.EEG (Electroencephalography) EEG uses electrodes to capture brain activity in different regions of the brain. Based on brain studies and theories of functions of brain regions these data is associated to arousal, learning etc. can be used to see the effect of one tool or application on users.
This method is very interesting but seems too expensive and time consuming for simple and work related applications like our project.
2.Eye tracking

2.Eye tracking
I think eye tracking has a good potential to be used to evaluate both pragmatic and aesthetic features.
I have seen examples of usability and information architecture evaluation by eye tracking, and also as in the example of the paper provided, user's enjoyment and aesthetic fulfilment.
In our case this method can be used to see which parts of the page user looks most, where are the attentions focused parts, where eye is fixed and also the sequence of the eye movement. This information in our system is only useful if it follows an interview to ask the user for his reason for each action.
3.Skin Conductance
Change in skin conductance can be associated to different emotional states. For example when a person feels empathy his hand's skin conductance changes, by measuring this changes we can have estimation of user's emotional state or arousal.
This method similar to EEG seems to be best fit for evaluating emotions not usability. Our system is very practical and does not involve strong emotions.
My choice to evaluate our system will be eye-tracking combined with a post test interview.
