In the earlier experiments in our lab, it was observed that prediction mechanisms slows down the text entry speed of users. This project attempts to design a mechanism for text prediction for Marathi on Swarachakra keyboard for smart phones. The 2 important hypothesized reasons which account to cognitive load were: Interface requires users to shift attention constantlyPredictions are displayed in a prediction window which generally is on top of the keyboard. If intended prediction does not appear in the first go, user do incremental addition of characters and look for prediction. In this he/she constantly, shift his/her attention from keyboard to prediction window. This visual discontinuity is one of the reason for worse performance of current prediction systems. Users are unable to build a conceptual of the prediction system- Novices or Intermediate users have not built the conceptual model of predictions of predictive system. For them, the behaviour of the system is completely uncertain. If there is word which a predictive system won’t predict, these users still keep looking for it. This is another potential reason for worse performance of current predictive systems. In this project, I designed a new predictive interface for Swarachakra Marathi keyboard maintaining the design continuity with keyboard. Based on the hypothesis of the long time required for conceptual model creation of predictive system and the still the uncertainty about the predictions, corpus of the new predictive keyboard is thresholded to 1000 words which covers 47.33% of Swarachakra corpus. The project is an experiment to test whether these factors have an effect on cognitive load and in-turn on the performance of the predictive systems for Marathi. The project was evaluated with Swarachakra with prediction chakra and More corpus (Top 20,000 words which contributes to 79.88%) and Swarachakra without prediction. A within subject study was carried with 5 users. Questions like Will interface change bring a difference in performance of keyboard? Will thresholding a corpus help in fast and precise building of conceptual model of predictive system? Will prediction help at the first place in improving performance of the keyboard? were tried to answer in the evaluation. Swarachakra without prediction performed the best
