The Mood Monitor• Wearable Sensors– Heart rate monitor– Galvanic Skin Resistance Sensor– EEG, EOG, etc.• Attached to a wearable sensor board withBluetooth capability• Sensor readings are monitored by anapplication on the phone• Aural feedback is provided to user based onhis physical properties– Musing changes with mood *Idea/funding from Michael Reiser

NHS Themed Utility App• Personalinformation• Appointments• Notes• NHS relatedservices

…NHS Themed Utility App• Nearest services– Address– Walking/Drivingdirections

…NHS Themed Utility App• Fall Detector– Uses accelerometer to detect if the phone has„fallen‟– Starts a visual + audio alarm– If the alarm is not stopped manually, a messageis sent to the next of kin and/or emergencycontact containing personal information and lastknown location of the phone• Help request– One touch help request• Same message as above, only done manually by theuser

Summary• Smartphones– Are computationally powerful– Are interactive computing platforms– Have a variety of on-board sensors– Have different type of communication interfaces– Can integrate with server-side/remoteapplications– Are the closest, readily available and one of theeasiest to carry computing devices available tousers– Possibly lead the list of devices in terms of timespent nearest to a user over its lifetime.

WorkshopSlide Option 1• SA Characterisation• Requirements ranking & comments• Profiling, monitoring, information +• Social sharing -

Evaluation Objectives• Obtain feedback to inform early design concepts• Identify the most appropriate design elements to include• Check for usability problems and performance issues• Ensure user participation from the start• Assess use in practice – from pragmatic, user experience andclinical perspectives

Data collection• Cooperative Evaluation & post-taskinterviews– Observation notes, pictures, audiorecordings– Video– Logging usage profiles• User Self-reporting– Usage logs and diaries (electronic andpaper based)

Some initial areas for analysis• Learnability and ease of use• Efficiency• Errors• User satisfaction and experience• Effectiveness• Technical support needed

App Development• Android + HTC Desire• Interaction Logging• Exportable Databases• Harnessing Student Interest & BuildingExpertise
