10. Swarachakra  Logically structured (based on the structure of the script)  All consonants visible  Wheel with vowel modifiers pops up around the consonants 10

11. Swarachakra 11

12. Three Designs – Disha  Also completely logical  Consonants displayed in groups –Most frequent character in the centre, accessed on tap –Other characters need a slide  Finger input possible – large area for each button 12

13. Swarachakra 13

14.  Independent variables –Age –Mobile phone experience –Education –Writing skills –Reading skills –Confidence of mobile phone task  First time usability test –19 words graded on difficulty –Speed, errors, confidence  Longitudinal test –10 short paragraphs typed over a period of 2 weeks in 10 sessions –Speed, errors, confidence Evaluations 14

37.  Simplify, un-sanskritise text – कळफलक सक्रीय  कुलुप काढले, विकल्प  पर्याय  Use explicit noun-verbs –Call (make call) = कॉल  फोन करा  Cool commands, metaphors are lost in translations –Go (where?) = जा  शॉर्टकट –Answer = उत्तर  फोन घ्या –Register = नोंद  आल्यागेल्या फोनच्या नोंदी  Don’t use English words where you don’t need them – अनलॉक  कुलुप काढा  Use English words where you need them –Loudspeaker = ध्व. क्षे.  स्पीकर –Contacts = संपर्क  डायरी, Edit number = संपर्क संपादन  नंबर बदला  Get the grammar right (sequence matters) –“ कॉल होत आहे निखिल ”  “ निखिल ला फोन होत आहे ” Principles of Good Localisation 37
