ENTRIES OPEN UNTIL THE 30th OF MARCH 2020:
Develop a wearable item that provides feedback to the user and / or support team about the consumer's health and/or safety, for example, number of steps, heart rate, if they are obstructed, if is the user is in darkness ...
Background and context of the challenge
Background and context of the challenge
Coaches and players in sport use activity monitoring devices to review player performance, health and fitness during training and games. This allows the coach to review each of the players and how training can be improved for future games. A player can review their own performance, and compare it to previous sessions and other players in the same team to gain an understanding of their fitness and health and see which areas need further development. Using an activity monitor in a rugby game allows the player to receive immediate feedback on their performance and allows the coach to monitor each player and make adjustments to the team. The data gathered during a game can be compared with training sessions to review each of the players and a team. An activity monitor that can track GPS will provide each player with their cluster location during a match and sprint duration / location.
A device you will all be familiar with is a Fitbit, this is used on a personal level for players who want to understand their own performance during exercise / games. This devices is worn as a watch and provides feedback on heart rate, steps, active minutes, pace, distance, stationary time, GPS and much more. All of these sensors provide feedback on a small screen on the watch which is worn by the user, this provides them instant feedback during their exercise. Once they have completed their exercise, they can upload the data to the app which allows the user to compare data gathered to previous sessions and against their friends on the app. This is very similar to a smart watch which provides similar feedback to the user during and after a sport activity. The device uses the following sensors in the device: 3-axis accelerometer, gyroscope, compass, light sensor, optical heartbeat sensor, an altimeter and Bluetooth for communicating with the phone when transmitting data.
Apex statsports is an activity monitor built for the sport market to monitor player performance during training / matches. This system uses a variety of devices that pulls data together to provide information on the player. Devices are used to measure specific aspects of the player and can be worn inside small pockets in the clothes. Most of these devices do not provide any direct feedback to the player. Only once the activity is complete can the user review their performance but their device allows live results during training or a match for the coach. The devices records a wider variety of information such as accelerations, decelerations, GPS player location which provides the software with additional information allowing it to calculate a wider variety of results on player performance. The device uses the following sensors in the device: 3-axis accelerometer, gyroscope, magnetometer, GPS module, heartbeat sensor, an altimeter and Bluetooth / wireless for transmitting data.
What could you use?
What could you use?
To help you on the start of your project, we are going to cover some devices which can provide feedback to the user and coach with a variety of built in / attached sensors
Crumble
Difficulty: Easy
A Crumble is a small device which has no built in sensors but you can add a variety of sensors to monitor the sporting activity. It also allows for a battery pack which allows portability. The external sensors the device can monitor are; accelerometer, compass, light, proximity and temperature. The device doesn’t have any built in Bluetooth / wireless for transmitting data, therefore it would only provide direct feedback to the user of the device using sparkles / digital display.
The device can only be programmed using a blocked based system.
Here you can find some examples of projects other people have done with a crumble:
BBC micro:bit
Difficulty: Easy / Moderate
A BBC micro:bit is a small device that can be powered by a battery pack, which makes it very portable if you are going to build a wearable device. It has several built in sensors; accelerometer, compass, light, proximity and temperature which can provide a variety of feedback to the user using the built in LEDs. This device also incorporates a Bluetooth / radio transmission which allows it to communicate with other such as a phone or another BBC micro:bit.
The device has an edge connector that allows you to connect external sensors / devices to monitor other aspects of the player performance. Some sensors that could be used to expand the analysis of the player are; ultrasonic distance sensors, switch, reed, proximity touch.
The device can be programmed by a blocked based system, java and python.
Here you can find some examples of projects other people have done with a BBC micro:bit:
· Accelerometer sensor / Simple accelerometer
· Radio to connect multiple micro:bits
Raspberry PI
Difficulty: Moderate / Hard
A Raspberry PI is a small device which will provide extra flexibility as it will allow a wider variety of sensor monitoring at the same time with live feedback to the support team and user. The device can be powered by an external battery pack for portability with Bluetooth and wireless data communication with other devices. All the sensors for this devices will be external, here is a list of some available sensors; accelerometer, compass, light, proximity, temperature, pressure, GPS and many more.
The device can be programmed using a variety of programming languages.
