(p=0,205)

User Tests (Debriefing)

Main challenges due to lack of knowledge

and fear to fail

Users didn’t know where to start

Users that use technology found the tasks

easy to complete

CONCLUSION

Conclusion

Interaction with close friends and family is

desired: PAELife is a solution to bring

people together

Users found interesting to have more

ways to interact with their families

Conclusion

Include the users in the development

process since the beginning

Known features for seniors are to be taken

into consideration

Keep tasks simple to avoid abandonment

Conclusion

Conclusions regarding the achievement of

the objectives are not as accurate as desired

Future Work

Explore more ways to visualize activity

Develop new ways to display groups and

contacts management

Find ways to test the solution with real

data
