Display system and position indicating device

A display system, comprising:

• a position indicating device;
• and
• an information processing apparatus having a display screen and a sensor that, in operation, detects a position indicated by the position indicating device,
• wherein the position indicating device includes:
• a casing,
• an interaction circuit disposed inside the casing, wherein the interaction circuit, in operation, exchanges a signal with the sensor of the information processing apparatus, and wherein the interaction circuit and the sensor of the information processing apparatus interact with each other through electromagnetic induction, and
• a securing member that, in operation, secures the casing to the display screen of the information processing apparatus, and
• wherein the information processing apparatus includes:
• a position detection circuit that, in operation, detects the position indicated by the position indicating device in a state of the casing being secured to the display screen through the securing member, based on the signal exchanged by the interaction circuit of the position indicating device with the sensor of the information processing apparatus, and
• a control circuit that, in operation, performs control to display a given display image on the display screen with the position indicated by the position indicating device and detected by the position detection circuit used as a reference.
