User Guide for Oral B Braun 5000 Toothbrush
The Oral B Braun 5000 SmartScreen Toothbrush is recommended for use by persons above the age of 3 years. It is recommended for use by persons who have reduced physical, sensory, and mental abilities. The user may not have the necessary experience or knowledge and as such may require to have been given supervision or instruction concerning the use of the appliance in a safe way. The user guide is keen to mention all the hazards involved to ensure maximum safety of the users. This Toothbrush has an extended feature beyond the electric brushing; it can connect to one’s smartphone. The connection to the phone requires communication via an application. It is recommended that the user deactivates the radio transmission after turning off the toothbrush. Turning off the Toothbrush is done by pressing the on/off button for a period of 3 seconds. The process of turning off the toothbrush causes the three indicator lights to flash simultaneously.
- To critically analyze and use complex decision making to research and determine the appropriate software engineering tools and methodologies to use in the case study.
- To critically analyze and develop artefacts to define processes for quality assurance, risk management and communication in large software development projects.
- To implement quality assurance activities in order to verify user requirements and validate design decisions.
- To develop a state transition diagram including both the toothbrush and the SmartScreen.
The toothbrush has a battery unit or charging unit which stores the power for use. It has a SmartScreen which allows the toothbrush to connect to the phone App. The smartphone App can run on iOS or Android Operating Systems. The App guides one through the entire Bluetooth pairing procedure. The radio connectivity is limited to Bluetooth wireless technology. The toothbrush is operated by turning it ON at the power mode selection point. The moment the toothbrush is turned ON it connects to the application on the Smartphone and starts sharing information. The toothbrush is comprised of:
- Power Mode selection (On/Off)
- Pressure Sensor light
- Charge Indicator light
- Low charge indicator light
- Charging unit which has the basic charger and brush head compartment with protective cover.
- Smartphone holder depending on the model
- Handle that is fitted with radio communication technology (Bluetooth Technology)
The Bluetooth 4.0 wireless technology is employed to enable connection with the iOS or Android based smartphone. The smartphone needs to be in a close proximity of about 5m distance. It is recommended to place the connecting smartphone safely in a dry place. The smartphone holder can hold your smartphone while using. Make sure your phone fits the stand and keeps stable. A user guide on the operation of the toothbrush is available on the smartphone app.
The smart guide instructs on the usage of the toothbrush as well as the different parts.
The smart guide provides an environmental notice. The product contains batteries and/or recyclable electric waste. For environment protection one must not dispose in the household waste, but for recycling one needs to take it to the electric waste collection point in the Country
State charts are used to model the behavior of autonomous and reactive systems. These are systems that are event driven, they react to internal- timeouts- and external stimuli. A reactive system is one which must continuously react to the external and internal stimuli. The state chart is given as,
?????????????????????????????????????=????????????????????−????????????????????????????????+
?????????????????(????????????????????????????????????????????)+?????????????????????????????????????????????????(????????????????????????????????????????????)+
???????????????????????????????????? ????????????????????????????????????????????????????
Mode of Operation
The state transition diagram is composed of the states and the transitions. The transitions from one state to another happen when the event that is labelled on the arc occurs and the conditions are true. The output of the state transition diagram can be associated with the transition. State charts extend the system with refinement, clustering and the use of logical controls such as AND, XOR decomposition of states. The next process seeks to validate the behavior of the state charts. This seeks to find out if the system works as intended.
Mode of Operation |
Description |
1. Daily clean mode |
It is the standard default brushing mode, which is used to daily cleaning the tooth and mouth. |
2. Deep Clean Mode |
It can extend the brushing time from default brushing time. In this mode, it will take 45 seconds for each quadrant and totally it takes 3 minutes brushing time, to clean the entire mouth. |
3. Sensitive Mode |
It helps to clean very sensitive areas of the mouth. It gives a feel of first-class fresh mouth. |
4. Whitening Mode |
It polishes the enamel gently, and it is possible to turn on this mode for either the daily use or for an occasional purpose. |
5. Gum care mode |
It helps to strengthen the gums by massaging smoothly. |
6. Tongue Cleaning Mode |
It cleanses the tongue gently, and it is possible to turn on this mode occasionally or for the daily use. |
The toothbrush is powered on after being setup. During the setup, the toothbrush is wet and toothpaste is applied on it. The timer is set to either the professional mode timer or the 2 minutes timer. When the toothbrush is all set up and the brush mode is selected, the toothbrush can now clean the 4 quadrants within 30 seconds each. If the user applies too much pressure while brushing, the toothbrush detects the increase pressure and warns the user using a red indicator light. After completing this, the brushing mode will be changed, the default brushing mode can be returned back by pressing and holding on the mode button, for some time. Even if the device is switched off, while brushing, the state of the previous brushing mode is saved. If the user forgets to resume the mode for more than 30 seconds or briefly pressing the mode button, it will automatically reset to daily clean mode.
The SmartScreen runs on the smartphone and seeks to provide instructions to the user while brushing their teeth. The App is started. It synchronizes with the toothbrush when powered on. It takes some few seconds to start and then it displays the brush modes and other instructions. After the user finishes brushing the app can be closed.
Tests are based around the conditions that could cause the user to err.
- Applying pressure while brushing – indicator turns RED.
- Power is less – indicator turns RED.
- Power is enough – indicator turns GREEN.
- Brushing mode – All the quadrants are covered after 30 seconds of brushing each.
Conclusion
In a nutshell, the system performed a black box test design technique in which the test cases were designed to execute both the valid and invalid states of the transition. There was a sequence of events that occurred and conditions that apply to those events. When the proper handling of a particular event/condition situation depends on the events and conditions that have occurred previously in the set conditions or in the past tests. The smart App records all the data on every time one brushes their teeth using the Oral-B Braun 5000 toothbrush for future analysis and trends. The information can be used by Dentists or any other medical personnel to track dental health.
