The document describes a smart healthcare monitoring system for independent living. Some key points:
- The system collects data from sensors monitoring daily living activities, physiological signals, and the environment to determine a person's wellness and ability to live independently.
- Sensors are deployed throughout the home to monitor activities like using appliances, mobility, and vital signs. The data is analyzed to recognize patterns and forecast wellness.
- Wellness is determined based on indices measuring inactive time and excess usage of appliances. The indices are improved over time using dynamic thresholds.
- Patterns in sensor activity are analyzed to detect irregular behaviors that could indicate issues. Forecasting is used to predict daily activities and identify deviations.

IoT is a combination of hardware and software technology that produces trillions of data through connecting multiple devices and sensors with the cloud and making sense of data with intelligent tools
IoT in Healthcare is a heterogeneous computing, wirelessly communicating system of apps and devices that connects patients and health providers to diagnose, monitor, track and store vital statistics and medical information.
Healthcare focused IOT technology is expected to be a $117 billion market by 2020 (a mere 5 Years out). A remarkable projection that is attracting a lot of big vendor focus as well as startup activity.
The feedback from the HC professionals I interviewed for this talk was that IoT for healthcare has to happen, is already happening, and the scale will be exponential. It will be embraced by the Boomers and Medicare. However, as I’ll get to, there will also be significant resistance from many quarters.

Design and Development of Mental Health Monitoring System using Multiple Sens...ijtsrd
There has been a revolution in the use of mobile health devices for monitoring physical health. There is more recent interest in whether these devices can also be used for monitoring symptoms of mental illness. The paper discusses how mobile based system can be employed for detecting physiological signs of stress. Stress causes deviations in biometrics such as EDA, heart rate etc. measurement of these biometrics using a handheld device can allow patients to self monitor and clinicians to detect the early warning signs. The system developed is employing Arduino UNO to interface sensors like temperature sensor LM35, pulse oximeter MAX30102, pulse sensor, GSR sensor and LCD.

27. Limitations
• Seasonal variations such as day of the week,
weekly, monthly are not taken into
consideration therefore it is likely that more
false warning messages will be generated.
• The threshold value of wellness indices was
derived to 0.5 and has been considered as safe
limit beyond which a warning message is sent to
the elderly/healthcare provider regarding the
daily activity behaviour.

30. Advantages of Improved Wellness Functions:
• For linear wellness indices (β1 and β2) the
threshold value was kept at 0.5 for generating
irregular behaviour warning messages.
• The improved wellness index β1,new, β2,new allow
more time to generate warning messages for the

• It was also observed that at 50% of the time
period the new wellness functions indicates a
wellness of 62%, better than 50% of the
previous wellness indices.
31. Dynamic – Maximum Inactive Usage and
Excess Active Usage Durations (T, Tn):
• T = δ (C1t – C1t-1) + (1 −δ) Tt-1
C1t = α (xt) + (1 − α) (C1t-1+ Tt-1) + St
Tn = δ (C2t – C2t-1) + (1 −δ) Tnt-1
C2t = α (xt) + (1 − α) (C2t-1+ Tnt-1) + St
• T: Trend of the Maximum Inactive usage Durations,
• Tn: Trend of the Maximum excess active usage durations,
• C1t, C2t: Seasonal trends;
• xt is the object usage observation at the current time,
• s is the number of periods in one cycle (week) (i.e. s=7),
Tt=(1/s)((xs+1-x1)/s+ (xs+2-x2)/s+…. (x2s-xs)/s)
• α, δ are the smoothing parameters (0 to 1), selected by minimizing mean
square errors.
• St is the seasonal term (for spring =1, summer=2, monsoon=3, autumn=4,
winter=5, prevernal=6)

37. Sequence Pattern Analysis* of Data Mining
Sequence Pattern: A pattern (a set of items, subsequences,
substructures, etc.) that occurs frequently in a data set.
*First proposed by Agrawal, Imielinski, and Swami [AIS93] in the context of frequent
item sets and association rule mining.
Ex: Let Sensor_ID={FR,CR,R1,KT}
Let t1=(FR,CR),t2=(FR,CR,R1) and t3=(KT) be three sets of sizes 2,3 and 1.
A eq ence ‘ ’=<t1,t2,t3> = <(FR,CR),(FR,CR,R1),(KT)> e esents a
length |S|=6.
A Sequence S1=<(FR,CR),(FR,CR,R1),(FR,CR,KT),(CR),(CR,CR)>
supports S
A “Sequential Database” Expected Data Base(EDB) is derived from
Data Base(DB) by eliminating certain Sequences
38. • Algorithm:
Sensor Activity Pattern–Pruning (node n= 𝑠1, 𝑠2, 𝑠3, … . . 𝑠𝑙 , Sn)
1.EDB = ∅,Support=0
2. For each (i ∈ Sn)
If ( (𝑠1, 𝑠2, 𝑠3, … . . 𝑠𝑙, 𝑖 ) is frequent )
EDB = EDB ∪ 𝑖
3. For each (i ∈ EDB)
4. Sensor Activity Pattern-Pruning((𝑠1, 𝑠2, 𝑠3, … . . 𝑠𝑙, 𝑖 , EDB, all
e ements in EDB eate than ‘i’ and satisfies Support(EDB) //
Generating EDB at node i that satisfies Support for the SAP
Support (EDB): If SAP is infrequent, and in order for the SAP to
propagate to frequent then it should have a length at-least σ−1(SAP).
