Touch sensing device, touch sensing unit, storage medium and touch sensing method

A touch sensing method comprising:

• receiving closed sense signals from a first contact and second contact provided at each of a plurality of keys, the first contact and second contact successively being closed in accordance with a key press operation;
• on the basis of the respective closed sense signals received from the first contact and the second contact, counting a first count value that indicates a duration from when the first contact is closed until the second contact is closed;
• counting a second count value that indicates a duration after the counting of the first count value ends;
• comparing the second count value with a pre-specified attainment duration value and, when a result of the comparison satisfies a predetermined condition, outputting a control signal;
• and,
• when the control signal is received, sending sound emission information instructing an emission of sound by a sound emission controller, the sound emission information including touch information based on the first count value.

A non-transitory computer readable storage medium having stored therein a program executable by a computer that causes the computer to execute steps comprising:

• a receiving step that receives closed sense signals from a first contact and second contact provided at each of a plurality of keys, the first contact and second contact successively being closed in accordance with a key press operation;
• a first counting step that, on the basis of the respective closed sense signals received from the first contact and the second contact, counts a first count value that indicates a duration from when the first contact is closed until the second contact is closed;
• a second counting step that counts a second count value that indicates a duration after the counting of the first count value ends;
• a comparing step that compares the second count value with a pre-specified attainment duration value and, when a result of the comparison satisfies a predetermined condition, outputs a control signal;
• and
• a controlling step that, when the control signal is received, sends sound emission information instructing an emission of sound by a sound emission controller, the sound emission information including touch information based on the first count value.
