## UM RAFBÆKUR Á HEIMKAUP.IS

Bókahillan þín er þitt svæði og þar eru bækurnar þínar geymdar. Þú kemst í bókahilluna þína hvar og hvenær sem er í tölvu eða snjalltæki. Einfalt og þægilegt!**Þú kemst í bækurnar hvar sem er**

Þú getur nálgast allar raf(skóla)bækurnar þínar á einu augabragði, hvar og hvenær sem er í bókahillunni þinni. Engin taska, enginn kyndill og ekkert vesen (hvað þá yfirvigt).

**Auðvelt að fletta og leita**

Þú getur flakkað milli síðna og kafla eins og þér hentar best og farið beint í ákveðna kafla úr efnisyfirlitinu. Í leitinni finnur þú orð, kafla eða síður í einum smelli.

**Glósur og yfirstrikanir**

Þú getur auðkennt textabrot með mismunandi litum og skrifað glósur að vild í rafbókina. Þú getur jafnvel séð glósur og yfirstrikanir hjá bekkjarsystkinum og kennara ef þeir leyfa það. Allt á einum stað.

**Hvað viltu sjá? / Þú ræður hvernig síðan lítur út**

Þú lagar síðuna að þínum þörfum. Stækkaðu eða minnkaðu myndir og texta með multi-level zoom til að sjá síðuna eins og þér hentar best í þínu námi.

**Fleiri góðir kostir**

- Þú getur prentað síður úr bókinni (innan þeirra marka sem útgefandinn setur)

- Möguleiki á tengingu við annað stafrænt og gagnvirkt efni, svo sem myndbönd eða spurningar úr efninu

- Auðvelt að afrita og líma efni/texta fyrir t.d. heimaverkefni eða ritgerðir

- Styður tækni sem hjálpar nemendum með sjón- eða heyrnarskerðingu

**Eiginleikar**
