ABSTRACT

For the next generation two-radio device with multi-touch screen, when a user wants to switch channels and talkgroups, multiple steps are required to accomplish this, which is inconvenient for first responders who desires to quickly switch radio channels and select talkgroups. In this paper, a method is introduced to achieve this with reduced steps, which can provide the improved user experience.

PROBLEM

As the common practice for a touch screen device, when a user wants to talk temporarily with the talkgroup other than the current selected active talkgroup, he/she has to turn on the screen, unlock the screen, select the talkgroup, and press PTT (Push to Talk) to talk. These time-consuming steps become unacceptable for first responders, especially in the situation that the distressed or downed responder desires a quick response. PTT is the key feature for LMR public safety users, so the need exists to conveniently select the target talkgroup or the target user for PTT without lighting up the display.

 

SOLUTION

    In the recent release of Android device with the compatible hardware as reference 1), it supports double tap to wake feature. Essentially in this feature, the device has the capability to receive the touch input from the touch screen even the touch screen is in off state. Taking advantage of this technology, the radio can detect the number of the touch points without turning on the touch screen. So combining operations of touching a screen and pressing PTT provides a way to fast select talkgroups. To be more specific, the number of the touch points detected upon the detection of PTT press determines the call type and the target talkgroup/target user. For example, 1).if no touch point is detected upon the detection of PTT press, the selected home talkgroup is used for talking; 2).if one touch point is detected upon the detection of PTT press, the announcement or the patched supper talkgroup is selected for talking; 3).if two touch points are detected upon the detection of PTT press, the private call is selected to target to his/her supervisor; 4).if three touch points are detected upon the detection of PTT press, all call (the call is all users) is selected for talking.

When a user presses PTT, the number of the touch points de...
