| Title: | Complement the touch information given by the smartphone's capacitive screens with the information received by the accelerometer and gyroscope |
| Issue Date: | 2014-07-15 |
| Abstract: | Currently smartphones are the consumer electronic devices with higher growth rate. The wide variety of functionalities that they provide is what makes them so desirable. We can use them to play, to communicate, to take pictures, to guide us, to work, and more. For that to be possible the smartphones have several built-in sensors, which make them much more interesting. This project amis to use smartphone embeded sensors to complement the information given by the smartphones touch screen with information given by the accelerometer and gyroscope. In others words, using sensors like the accelerometers and gyroscopes,to provide new ways to characterize the touch. For that the accelerometer and gyroscope signals will be studied and several algorithms will be create, such as to detect touches using this two sensors, to determine the device position (hand or on surface), the hand and the finger used to touch on device and the touch force. |
| Description: | Currently it only is possible to obtain information about a tap on the smartphone's screen using the touch sensor. The goal of this project is to complement the information given by the smartphones touch screen with information given by the accelerometer and gyroscope and this way to extend the smartphone's touch capabilities with data such as tap strength, smartphone's holding position while taping (if it is on the users hands or laying on a hard surface) or which finger the touch was performed (thumb or index finger). Using sensors to detect touches is not a new idea, as there is already research which use the smartphone accelerometer to infer which keystrokes were made on a touch screen, and use the accelerometer information to know when there was a tap on the virtual keybord is made even before the touchscreen detects it, this project aims to use this information to other proposes, getting new information on a touch event and process that information in order to be useful to the user or developer party. |
