Match the following : Codes : a b c d List – I List – II a. Tablet, Joystick i. Continuous devices b. Light Pen, Touch Screen ii. Direct devices c. Locator, Keyboard iii. Logical devices d. Data Globe, Sonic Pen iv. 3D interaction devices
i ii iii iv
Interactive graphics input devices are grouped by how they deliver input.
a. Tablet and joystick give a smoothly varying stream of positions as the stylus or stick moves, so they are continuous devices → i.
b. Light pen and touch screen let the user point at the displayed object on the screen itself, so they are direct devices → ii.
c. Locator and keyboard (string device) are among the logical input device classes (locator, stroke, string, valuator, choice, pick), defined by the kind of data they return rather than by hardware → iii.
d. Data glove and sonic pen sense hand/pen position in three-dimensional space, so they are 3D interaction devices → iv.
The matching is a–i, b–ii, c–iii, d–iv.
Hence, the answer is i ii iii iv.
