PoC (Push to Talk over Cellular) All answers
Delivers audio (voice) to the target group like walkie-talkies. It is not necessary to call every group member one-by-one to form a group.
Advantages
Immediate audio connection between group members. All group partners are allowed to activate a PoC connection. Supports excellent interpersonal communication and immediate sharing of pictures and other documents in a group. Is cost effective because of the use of GPRS connection.
Disadvantage
Is Half Duplex by nature. When one is speaking, others can only listen. Mobile phones must support the Session Initiated Protokol (SIP)
PoC as a Facilitator for mLearning
The potential to use PoC was evaluated in the ViCaDiS Project as follows:
- Push to Talk Communication in Teaching and Learning
- Immediate Sharing of Documents
The potential and probability of use is on reasonable high level in question 2 and in question 1 on moderate level. Lets spread the results in a normalised diagram (description) to see how answers are related to each others.
The first development activities should concentrate on:
- Immediate Sharing of Documents
Commenting/Discussion subjects
- What kind of features should be considered in educational use of PoC?
- Do you have positive/negative experiences related to educational use of PoC?
- What are the implications for ViCaDiS Work Packages?
